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

While an uptick in benzene contract prices of about 40¢/gal was expected in November, these sources predicted that PS suppliers might opt to give up some margin due to high volumes of imported PS. According to PCW’s Barry, one resin distributor described the price gap between imported and domestic resin as “unsustainably large.”

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.

When, how, what and why to automate — leading robotics suppliers and forward-thinking moldmakers will share their insights on automating manufacturing at collocated event.

For the November-December timeframe, these sources noted signs that prices were bottoming out, with flat to slightly lower pricing expected. “I think we haves some visibility of a bottom forming with a little bit of further drop,” said Newell. Barry saw potential for further price reduction in the fourth quarter, noting that demand in the global PP market was down and China was becoming a regular exporter of PP, the latest competitor for U.S. suppliers.

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

Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.

A halt in the pricing plunge for PE, PP, and PS appeared to be shaping up going into November, owing primarily to suppliers reducing their swollen inventories by throttling back production rates and, in the case of PE, multiplying attractive offers for exports and the domestic spot market. Still, first-quarter 2023 looks to be a buyer’s market for all five major commodity resins.

Gifted with extraordinary technical know how and an authoritative yet plain English writing style, in this collection of articles Fattori offers his insights on a variety of molding-related topics that are bound to make your days on the production floor go a little bit better.

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.

While suppliers have throttled back production, these sources say there is a lot of material to be had and that heavily discounted spot deals were on the table. There was also substantial new capacity coming on stream, with ExxonMobil starting up its new plant and Heartland Polymers readying its PDH and PP units. Greenberg confirmed that some PP suppliers were offering deeply discounted railcars for higher volume orders as they aimed for better positioning in first-quarter 2023. He reported that there was good ongoing demand for packaged truckloads from processors that had drawn down their stocks and now required more material, and from others waiting for late railcars to arrive.

Both sources noted that falling PVC export prices have continued the downward pressure on domestic prices, along with increasing supplier inventories. However, Kallman reported that suppliers have exported a substantial volume of PVC and that Formosa had planned a shutdown of its Louisiana plant through November, which would perhaps result in a more balanced market. He noted that with the exception of wire and cable—the “most resilient market sector”—PVC demand is off in nearly all categories.

Multiple speakers at Molding 2023 will address the ways simulation can impact material substitution decisions, process profitability and simplification of mold design.

Polyethylene prices for October appeared to hold even and were expected to be generally flat for the last two months of the year, according to David Barry, PCW’s associate director for PE, PP, and PS; Robin Chesshier, RTi’s v.p. of PE, PS, and nylon 6 markets; and The Plastic Exchange’s Michael Greenberg. Reporting on one longtime market watcher’s projections, Barry noted, “Don’t expect any big price swings for several months.” Meanwhile, suppliers notified customers they were postponing their increases of 5-7¢/lb from October to November, though these sources saw this move as mainly an effort to halt any further decline.

After successfully introducing a combined conference for moldmakers and injection molders in 2022, Plastics Technology and MoldMaking Technology are once again joining forces for a tooling/molding two-for-one.

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.

RTi’s Chesshier ventured that PS tabs could remain flat this month but may rise if benzene prices move up again. Meanwhile, the implied styrene cost based on a 30/70 formula of spot ethylene/benzene fell by nearly 2¢/lb to 36.2¢/lb going into November. Implied styrene costs have been hovering in the mid-30s since late August, according to Barry.

According to the collaborators, the addition of aPHA to the Dongil straw was inspired due to the flow property improvements aPHA provided for processing, in addition to making flexibility easier to achieve. Apparently, the processing time for PLA-only based straws entails a long cycle time. The addition of aPHA improved processing time by 50% using Dongil’s technology. The value proposition was enhanced performance along with a positive impact on the bottom line. CJ Biomaterials aims to explore the value proposition encountered by Dongil to see if they can add value to other PLA-only straws to improve flow properties during manufacturing to improve overall cycle times and profitability

Beyond Plastic and partners have created a certified biodegradable PHA compound that can be injection molded into 38-mm closures in a sub 6-second cycle from a multicavity hot runner tool.

Polypropylene prices in October were on the way down by double-digits, as propylene monomer contracts were expected to settle 9¢/lb to 11¢/lb lower, along with an expected margin contraction of 4¢/lb to 5¢/lb, according to PCW’s Barry, Spartan Polymers’ Newell, and The Plastic Exchange’s Greenberg. The market was characterized as very well supplied, amid continued lackluster demand, despite suppliers throttling back plant operating rates to a low of 70%

Both PCW’s Barry and RTi’s Chesshier ventured that this relative stability might well be shaken up within the first quarter, due to the substantial new capacity being brought on stream by Shell and Baystar, the new 50/50 joint venture between Borealis and Total Energies. Combined production will represent a 10% increase in annual domestic capacity. Noting that early 2023 will remain a buyer’s market, Chesshier said that suppliers will face further challenges from lower global demand. As Barry put it, “The export packaging pipeline was viewed as a likely bottleneck for producer export sales in the coming months. Prices in Asia were softening as well-stocked Chinese producers lowered offers to stimulate demand and Southeast Asian markets followed the softer trend.”

Contract prices fell a total of about 11¢/lb in the third quarter, with more dramatic price drops in the spot market. As October approached, spot prices began to stabilize. Going into November, Greenberg put it this way: “Spot PE price were holding firm for three weeks in a row. Even as PE spot levels have seemingly found a floor, buyers continue to enjoy good availability for most grades near these yearly lows.” He did note that some more niche grades, such as injection molding LDPE, EVA, POE and rotomolding resins had been in tighter supply, and have good underlying demand if better supplies surface.
