Addressing hot-runner benefits, improvements, and everyday issues from the perspective of decades of experience with probably every brand on the market. Part 1 of 2.

ICP- and IDP-based compounds promise to remedy all these shortcomings. They typically create a more uniform and complete conductive network than do dispersions of discrete particles of carbon black or even stainless-steel fibers. ICPs and IDPs often work at lower loadings, detract less from matrix-resin properties, and are more colorable than conventional products. IDPs even allow formulating transparent or translucent ESD products.

Take a deep dive into all of the various aspects of part quoting to ensure you’ve got all the bases—as in costs—covered before preparing your customer’s quote for services.

Ticona recently introduced an ESD acetal grade for auto fuel-line parts. Celcon CF802 uses novel compatibilizer technology to bond reinforcing fiber to the matrix. That is said to minimize mechanical property tradeoffs and increase resistance to attack by fuels.

While the major correction in PP prices was finally underway, generally stable pricing was anticipated for the other four commodity resins.

LNP’s Ultra-Clean Stat-Kon slate of ESD materials for high-purity applications uses nano-tubes in PEEK and PEI compounds for wafer-carrier and disk-drive components. Ionic contamination is said to be 65% to 90% lower than in carbon-fiber compounds.

When determining the best ejection option for a tool, molders must consider the ejector’s surface area, location and style.

Neil Hardwick, Noveon's marketing manager, says a recent initiative is tri-layer HIPS sandwich structures that optimize IDP cost-effectiveness in thermoformable sheets. For instance, one structure puts carbon-filled HIPS at the core (providing good volume resistivity and EMI shielding) while the skin layers include an IDP/HIPS compound to eliminate slough ing while ensuring excellent surface dissipation.

One of the difficulties with carbon black is that small changes in concentration in a plastic compound can produce large leaps in conductivity. The “smoother” ESD performance curve offered by ICP-based compounds is a big advantage, Dahman says. It is far easier to tailor performance for a specific end-use and thereby optimize cost-performance. ICP compounds are priced at an intermediate point between carbon-black and carbon-fiber compounds.

Bayer has concluded that blends of various carbon-based conductive additives, including Hyperion’s nano-tubes are a cost-effective way to tackle e-painting needs. Indeed, compatibilized blends of carbon additives are employed in new 30%-glass nylon 6 and TP polyester molding compounds that reportedly provide superior surface smoothness in door handles, fuel flaps, and large exterior auto parts.

Stainless-steel fibers are the key ingredient in the Faradex line of EMI shielding compounds that LNP recently acquired from DSM. They are aimed more at consumer electronics and business machines, namely thin-wall housings for cell phones and computer equipment. Unlike carbon additives, stainless steel does not limit colorability, but the fibers are easily damaged in melt processing. LNP uses a special compounding technique to retain fiber length for good shielding.

A novel pitch-based carbon fiber developed by Conoco Cevolution will be manufactured at a 4-million-lb/yr plant in Ponca City, Okla., due to come on stream in the second quarter of this year. Samples are already available. Eduardo Romero, industry manager for electrical/electronics, says Cevolution’s mesophase pitch fiber offers an order of magnitude higher electrical conductivity than PAN-type carbon fibers and significantly greater stiffness as well. The stiffness can be tailored to specific end-uses. Other benefits are outstanding purity and high thermal conductivity. These fibers will be priced to compete with PAN fibers in some applications. Romero sees potential in ESD, EMI shielding, e-paintable auto parts, and fuel-cell plates.

Sustainability continues to dominate new additives technology, but upping performance is also evident. Most of the new additives have been targeted to commodity resins and particularly polyolefins.

LNP’s Stat-Loy family uses an IDP to impart permanent antistatic and ESD properties (109 to 1012 ohm/sq) to a variety of resins, including PC/ABS and a transparent ABS.

Although users will still have to get molds made to use the machine, the ability to pop out a small run of plastic objects without waiting multiple hours for a desktop 3D printer to finish a single print could make the LNS Technologies’ offering a useful tool for trial runs of products or offer greater capacity to small manufacturers and colleges.From the Kickstarter page:So what our machine offers is a way for individuals, small businesses or even large companies to use low cost aluminum molds to produce their own prototype partsff.  Or they can even make moderate production runs of a custom plastic product.

Designing a thermoplastic compound to conduct an electrical charge is difficult and costly, since most polymers are naturally ill suited to the task. Plastics generally have surface resistivities of 1012 ohm/sq or higher, which puts them at the insulative end of the electrical spectrum (see graph). That is advantageous in many uses, but is a liability in others. Indeed, some degree of electrical conductivity is critical to a growing number of plastics applications.

EMI protection is another area of major growth potential for conductive plastics in automotive. Stimulating factors are increased use of sensitive electronic gadgetry in cars, a pending shift to 42-volt battery power, and the need to preserve space under the hood, according to David Riffer, electrical-electronics market manager for EMS-Grivory. His company has long put carbon and stainless steel into ESD versions of its nylon 6, 66, and 12 compounds for automotive fuel-line and under-hood applications. Now, the company is moving into nylon EMI-shielding compounds using stainless steel as the conductive ingredient. These are aimed at automotive electronics as well as business-machine housings and coaxial-cable connectors.

Pat Collins, Hyperion’s marketing manager, says fibril-based compounds can cover the full electrical spectrum at loadings at least 50% lower than would be needed with carbon fibers (which are gigantic in physical size compared with fibrils). Retention of toughness and ductility with the nano-tubes reportedly far exceeds that for the best conventional conductive compounds. Viscosity is minimally affected, Hyperion says, so its fibrils are highly suitable for thin-wall molding and provide excellent surface quality in appearance parts. There is less differential shrinkage and part warpage than with conventional filled compounds.

RTP offers ICP compounds based on PP, PS, PE, and PC/ABS. These provide permanent ESD, accept 25% recycle content, and have a wide range of colorability. The compounds have potential in industrial packaging and containers, material-handling boxes and totes, and shelves and racks for electronics. RTP is working to stretch ICP compound performance into the EMI-shielding range (10 to 100 ohm/sq).

Additive manufacturing (AM) is great for plenty of applications, but it does have some disadvantages when it comes to certain areas. Industrial 3D printers may be able to build enough parts in one batch, thanks to a large build envelope, to make mass manufacturing worthwhile, but desktop AM systems are less useful for such applications.

Baystar's Borstar technology is helping customers deliver better, more reliable production methods to greenhouse agriculture.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

Processors with sustainability goals or mandates have a number of ways to reach their goals. Biopolymers are among them.

Ticona offers conductive PPS grades that utilize an unconventional carbon-based conductive. The novel ingredient is said to offer many of the benefits of nano-tubes at considerably lower cost. This additive and proprietary compounding technique are said to ensure precise “tuneability” of ESD performance. The materials are also described as clean—non-sloughing and low in ionic contamination and outgassing—making them viable for use in liquid-crystal displays, electronic storage media, and microelectronic carrier trays.

Because of its low cost, traditional carbon black is still the workhorse in conductive plastics. However, carbon black makes it difficult for compounders to hit a specific level of conductivity. It also imposes severe property tradeoffs and limitations on colorability. What's more, "sloughing" of conductive particles can damage microelectronic devices.

Jeff Frankish, director of global market development at PolyOne’s Compounds & Colors unit, says OEM users of conductive compounds are “raising the performance bar” for these materials. “Multi-functionality” is increasingly being built into formulations, he says. As examples, he cites ESD and EMI grades from PolyOne that are also lubricated, based partly on recycled resins, or modified to process on specific equipment.

Hyperion’s initial slate of nylon 6 and 66, PBT, and PC masterbatches has recently been broadened to include PEEK, PEI (GE’s Ultem polyetherimide), PPS, nylon 12, and PS. Coming next are PP, PET, and EVA masterbatches. Current uses include a nylon 12 that replaces metal in automotive fuel lines. It combines excellent ESD performance plus elevated toughness, which translates into the added safety benefit of increased rupture resistance. E-paintable compounds based on nano-tubes impart the necessary conductivity at just 2-3% loadings while offering a Class A surface quality.

In this collection of articles, two of the industry’s foremost authorities on screw design — Jim Frankand and Mark Spalding — offer their sage advice on screw design...what works, what doesn’t, and what to look for when things start going wrong.

There are even emerging applications for plastics to be nearly as conductive as pure carbon—such as bipolar plates and end plates for fuel cells.

Another advance is a novel class of vapor-grown carbon nano-tubes and nano-fibers. These impart a broad range of conductivity to plastics at far lower loadings than conventional carbon-based additives, while simultaneously providing reinforcement and enhanced thermal conductivity. However, the potential of these nano-carbon products is currently limited by their $50/lb or higher price tags. This compares with $15/lb for pitch carbon fiber and stainless steel, $8/lb for PAN carbon fiber, and less than $2/lb for carbon-black powder. Greater near-term potential is seen for a developmental low-cost pitch carbon fiber that boasts improvements in both conductive and reinforcing properties.

Automotive fuel delivery systems are a focus of interest for makers of ESD compounds. Parts subject to swift or turbulent gas flow (e.g., filler-line pockets or line connectors) require conductivity to thwart static build-up and the risk of sparks and explosion. That is a major reason why large-volume applications like fuel filler lines, chassis pipes, and fuel-pump housings are still overwhelmingly made of steel.

GE is also focusing on fuel filler doors, 78% of which are made of steel and painted on-line with other steel parts. GE sources believe that conversion of this application to plastics requires on-line e-paintable compounds. GE is proposing a nylon-modified PPO (Noryl GTX) made electrically conductive with carbon black.

Nano-tube-based compounds offering 104 to 109 ohm/sq surface resistivity at 4-7% loadings are offered by RTP. Scott Koberna, RTP product manager for conductive compounds, says RTP’s NTC-series compounds minimize occurrence of hot and cold spots and are suitable for high-purity ESD and e-paintable compounds. RTP puts nano-tubes into HIPS, acetal, and other engineering resins. NTC grades are priced 25% to 100% higher than comparable PAN-fiber compounds.

Suppliers of nano-carbons include Hyperion Catalysis, the sole commercial supplier in North America; Japan's Mitsui and Showa Denko; and an Applied Sciences affiliate, Pyrograf Products. The latter's developmental graphite nano-fiber is 100-200 nm in diam. x 100 microns long, giving it a 500-1000:1 aspect ratio. It's available in sample quantities at $70/lb. (A semi-works plant is being built.) At loadings of 0.5% to 5% by volume, Pyrograf's PF24 carbon nano-fiber boosts stiffness of plastics by 500% and drops their surface resistivity to the range of 1 to 1010 ohm/sq.

In recent years, others have introduced compounds based on IDPs comparable to (but different from) Noveon’s. New players include LNP, RTP, Lati USA, and DSM Engineering Plastics. DSM has just diversified its carbon-based ElectraFil line by adding IDP-based products.

Additive technology creates air pockets in film during orientation, cutting down on the amount of resin needed while boosting opacity, mechanical properties and recyclability.

While the melting process does not provide perfect mixing, this study shows that mixing is indeed initiated during melting.

DuPont is one firm working to broaden plastics’ opportunities in these applications. DuPont has developed a pair of acetal compounds for injection molding. Delrin 300AS and 300AT utilize carbon fiber to provide ESD capability (106 ohm/sq) and enhanced stiffness. Delrin 300AT has twice the toughness of a standard acetal. It is aimed at fuel-tank caps and filler pockets. Delrin 300AS exhibits 300% higher stiffness than standard acetals and is aimed at uses inside the tank—such as a support flange on sender modules (a device that primes the fuel pump). DuPont has also launched nylon 66 ESD grades, some of them glass-filled, and plans to launch ESD versions of its Zytel HTN high-temperature nylon.

Plastics Technology’s Tech Days is back! Every Tuesday in October, a series of five online presentations will be given by industry supplier around the following topics:  Injection Molding — New Technologies, Efficiencies Film Extrusion — New Technologies, Efficiencies Upstream/Downstream Operations Injection Molding — Sustainability Extrusion — Compounding Coming out of NPE2024, PT identified a variety of topics, technologies and trends that are driving and shaping the evolution of plastic products manufacturing — from recycling/recyclability and energy optimization to AI-based process control and automation implementation. PT Tech Days is designed to provide a robust, curated, accessible platform through which plastics professionals can explore these trends, have direct access to subject-matter experts and develop strategies for applying solutions in their operations.

The Plastics Industry Association (PLASTICS) has released final figures for NPE2024: The Plastics Show (May 6-10; Orlando) that officially make it the largest ever NPE in several key metrics.

Another driver is the trend toward electrostatic spray painting of automotive and industrial parts. This method, in which paint drops are positively charged and the parts are grounded (negatively charged), is generating a flood of "e-paintable" compounds whose conductivity is tailored to optimize painting efficiency. E-painting is said to reduce overspray by up to 50%, thereby cutting both cost and volatile emissions.

Hyperion's multi-wall graphite nano-tubes have 10-nm OD and are 10 to 100 microns long, for at least a 1000:1 aspect ratio. The small size and curvilinear shape of these “fibrils” makes them difficult to disperse in plastics. To ensure satisfactory dispersion, Hyperion supplies the fibrils in pelletized masterbatches containing 15-20% fibrils, which can be let down to as little as 0.5% by weight.

New conductive technologies are emerging, one being a class of polymers intrinsically able to carry a current along their polymer chains. Inherently Conductive Polymers and Inherently Dissipative Polymers (ICPs and IDPs) differ in the range of conductivity they impart and the mechanism involved. Both categories are now melt-processable and thus highly efficient at creating conductive networks when alloyed with a thermoplastic matrix polymer.

Cost is the major limit on nano-tube use, as Hyperion’s fibrils are priced at around $50/lb. Over the long haul, Collins argues, the start-up of world-scale plants will bring prices down.

Noveon (formerly part of BFGoodrich) has developed an IDP that works in the 106 to 1011 ohm/sq surface resistivity range, offering permanent static control. Noveon uses this IDP exclusively in its own Stat-Rite compounds for injection molding and extrusion. IDPs are generally elastomers (Noveon's is a TP urethane) that contain "charge-carrying blocks" able to conduct current, but in a more restricted part of the antistatic and ESD spectrum than is covered by ICPs. In some cases, the hydrophilic nature of an IDP helps boost conductivity at the part surface. In the past, thermal-stability limits confined IDP use to low-temperature matrix resins like HIPS, PETG, ABS, and TPU, but Noveon has recently expanded its Stat-Rite line to include PP and TPU/PC compounds.

Teknor Apex's Plastics Div. recently launched a family of flexible vinyl compounds designed for consistent ESD and EMI performance. Carbon-black-filled Vidux PVCs offer 100 to 108 ohm-cm volume resistivity in cable jackets, flooring, grounding mats, shielding, and other items used in cleanrooms, hospitals, and factories. At under $2/lb, they are said to be more cost-effective than alternatives based on carbon or steel fibers.

"Nano-carbons may prove to be in the 21st century what aluminum was in the 20th," declares Max Lake, president of Applied Sciences, an advanced-materials R&D firm in Cedarsville, Ohio. Like aluminum, he says, the miniscule, high-aspect-ratio nano-particles impart extraordinary strength and light weight. In plastics, nano-carbons can also significantly enhance both electrical and thermal conductivity.

It's no surprise, then, that underlying demand for conductive plastic compounds in North America is forecasted to grow 8-10%/yr from a current base of around 450 million lb.

Ultradent's entry of its Umbrella cheek retractor took home the awards for Technical Sophistication and Achievement in Economics and Efficiency at PTXPO.

A particular strength of ICPs is their ability to drain off static charge in a highly exact and reproducible way, says Sam Dahman, product development engineer at RTP Co. RTP holds exclusive North American rights to develop ESD compounds based on the only commercial polyaniline ICP, a product supplied by Panipol of Finland. A recent breakthrough by RTP and Panipol maintains thermal stability and ensures uniform dispersion of polyaniline during melt processing.Conventional carbon black tends to suffer twin deficits when used to impart ESD protection: It dissipates across a wide range of surface conductivities, while disparities in voltage also tend to persist on the part surface in the form of “hot” and “cold” spots. RTP data, for instance, show that a part made of one carbon-black-filled PP has a surface resistivity ranging from 105 to 1012 ohm/sq. A comparable ICP-based part consistently hits a narrow range of 106 to 107 ohm/sq.

Across the show, sustainability ruled in new materials technology, from polyolefins and engineering resins to biobased materials.

EMS-Grivory is also compounding nickel and zinc ferrite powders into nylon 12 and high-temperature nylons for use in “soft” magnets. These molded devices become magnetized in the presence of a current, thereby providing EMI protection for air-bag connectors and other sensitive control elements. Polymer magnets are more durable than the sintered magnets they replace, and also offer greater design freedom and the potential for lower-cost manufacture and assembly. Polymer magnets could also provide EMI protection to computers and appliances, Riffer says.

Implementing a production monitoring system as the foundation of a ‘smart factory’ is about integrating people with new technology as much as it is about integrating machines and computers. Here are tips from a company that has gone through the process.

“Today, there are more reasons and better tools than ever for making electrically active compounds,” declares Mark Kaptur, product marketing manager for conductive compounds at LNP Engineering Plastics. One reason is more intensive use of electronics in cars, portable consumer devices, and appliances—plus their on-going miniaturization. Both trends increase the need to protect parts from ESD and EMI.

Improvements in nozzle design in recent years overcome some of the limitations of previous filter, mixing, and shut-off nozzles.

Electrostatic paintability without need for a conductive primer is another property that makes conductive plastics attractive to auto makers. GE Plastics is taking a new tack in formulating Noryl PPO alloys for e-paintable auto parts. Five years ago, GE was one of the first to adopt Hyperion’s carbon nano-tubes in Noryl 990E, used in mirror housings. That grade has been discontinued for unstated reasons, but cost certainly played a role in the decision.

Mixed in among thought leaders from leading suppliers to injection molders and mold makers at the 2023 Molding and MoldMaking conferences will be molders and toolmakers themselves.
