Reported Todd in late November, “A market pundit changed its prediction for November prices from down 2¢/lb to 1¢/lb. This was a bit of a surprise to some market watchers, who pointed out that spot ethylene prices had started November at 21.25¢/lb and then dropped by 3¢/lb to 18.25¢/lb at midmonth.” She also noted that Formosa Taiwan dropped its export prices a total of $140/mt in the October-November time frame, resulting in domestic suppliers having to drop their export prices.

Polyethylene prices were largely expected to drop by 3¢/lb within November-December, which would nix the September 3¢/lb increase, which brought the total increases this year to 12¢/lb. This according to PCW’s David Barry, The Plastic Exchange’s CEO Michael Greenberg and resin pricing expert Robin Chesshier. As for this month, these sources would not be surprised to see suppliers issuing a new increase as is typical at year’s end, but note that barring any major adverse production event, such an increase would likely take a couple of months to implement.

Prices of volume resins were all heading downward by year’s end, and projections for at least the first month of first quarter 2024 are generally for flat or lower pricing, particularly for the five commodity resins as new year contract negotiations were underway. All this, with the caveat there are no major production disruptions caused by inclement weather or other unplanned feedstock, and/or resin shutdowns.
I’ve developed a list of plastics that I know could possibly react with one another. My bet is there are others that I do not know about. If you know of any others, please let me know.
Polystyrene prices dropped by 4¢/lb in November, having risen by a total of 10¢/lb between July and October, driven by higher benzene prices, according to PCW’s Barry and resin pricing expert Robin Chesshier.

Says PCW’s Barry, “There has been a lot of nonmarket adjustments being made so that most processors did not incur the full 12¢/lb. It has been a challenging market as buyers need to stay alert and not rely on published industry indices.” Chesshier notes that for November, the indices showed flat pricing for at least November. Moreover, all three industry pros note that in 2024 resin pricing contract negotiations, the buyers are definitely in the driver’s seat. Barry and Greenberg noted that suppliers have dropped export prices in order to move material, which contributed to the bearish sentiment. Adds Barry, “Exports are improving since the September-October time frame and that is due to domestic suppliers lowering prices. As an example, blow molding PE was selling at 33¢/lb to 35¢/lb in early November, from the previous 38¢/lb to 39¢/lb.”
Nylon 66 prices remained relatively static in most of the fourth quarter, though some decreases in nylon 66 compounds took place. This after a total decline of about 20¢/lb or more earlier in 2023, according to RTi’s Kallman. Depending on raw material price movements, he ventures a drop of 4¢/lb to 5¢/lb in January, as a result of new contract negotiations. The domestic market continues to be well supplied, including well-priced imports.
Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

You will hear true stories of hoppers being blown to and through roofs, endcaps blown through walls, etc. The gases produced upon resin decomposition generate extreme pressures, which can and do blow injection molding machine barrels into shrapnel. The accompanying photo shows the front zone of a machine barrel that blew into pieces. Imagine the damage if it had hit someone! This may not happen often, but it does occur, and you need to be aware its possibility.
Barry and Greenberg venture that PP prices could remain flat through December and possibly this month, noting that while monomer supply issues appear to have improved going into the last two months of the year, it was not yet evident on the market. They are more likely seeing January 2024 as the time for monomer price correction. Newell ventures there is potential to see a price drop in PP in December and perhaps more so this month. All three note that PP inventories are quite tight as suppliers have done a good job to throttle back production due to lackluster domestic demand.

ABS prices appeared to remain largely flat throughout the fourth quarter, despite one major supplier’s attempt to push through an increase. This after dropping a total of 15¢ to 27¢/lb in the previous three quarters, according to RTi’s Kallman. He notes that raw material prices peaked in October, and attractively-priced Asian imports continued to play a role in the market. For January, Kallman ventures ABS prices would decline as 2024 contract negotiations favored buyers.
Of course, safety in injection molding extends beyond material compatibility. High temperatures and pressures of 20,000 to 45,000 psi are needed to melt and inject plastic into complex shapes. While these machines are built robustly to handle these temperatures and pressures, it’s best take a serious look at the equipment on a regular basis and not assume all is OK. Do you review the machine/mold upon startup or during production to make sure these pressures and temperatures do not reach out and touch you or a coworker? For example, does the nozzle tip mate properly with the sprue bushing? Is a temperature zone overriding?

While the major correction in PP prices was finally underway, generally stable pricing was anticipated for the other four commodity resins.
Greenberg characterized the spot market as having ample PE grades across-the-board and reported that despite suppliers aiming for a November increase of 3¢/lb in November, the market has lost its upward momentum and larger buyers have been clamoring for a decrease. “We think that PE contracts will roll flat at best and would not be surprised to actually see 3¢/lb peel off.”

In fact, total demand for PP in 2023 appeared to be slightly positive, all owed to some exports activity. Says Barry, “PP suppliers are facing some challenges as a large number of PP imports are coming through in December from places like the Middle East and China.” These sources also note that some downward PP resin price adjustment is likely as ‘new kid on-the-block’ Heartland Polymers — as well as capacity increases from Invista and Formosa in second quarter — will make it a more competitive market. But, adds Greenberg, “Keep in mind though, any further upstream production issues could easily sway this market again since PP inventories throughout the supply chain are still considered tight.”

This is an issue whenever you change jobs to a new mold with a different resin. Are the two resins compatible or do they react with one another? No matter how hard you try to purge the previous resin from the system, small amounts will remain on the screw flights. Purging compound may help, but even a small residual amount of the previous resin can provide a catalytic effect. For example, if you accidently mix acetal (POM) with PVC, you and the rest of the people on the shop floor will have an extremely unpleasant emotional and physical experience. Small amounts of either of these two resins catalyzes the decomposition of the other polymer to gases.

PVC prices were expected to drop by 1¢/lb to 2¢/lb within November-December, after remaining flat in October, according to Paul Pavlov, RTi’s v.p. of PP and PVC, and PCW’s senior editor Donna Todd. Pavlov notes that suppliers’ margins and domestic sales across-the-board on PVC market sectors in 2023 decreased in comparison to both 2022 and 2021. He ventures that January prices are likely to be flat and perhaps a bit up depending on some market recovery, noting that suppliers’ plant operating rates were in the low-to-mid 80s percentile with inventory days at 16, versus a more typical 12-13 days.

Resin drying is a crucial, but often-misunderstood area. This collection includes details on why and what you need to dry, how to specify a dryer, and best practices.
In general, 2023 was ending with processors having more leverage than resin suppliers, with the latter having had a year of profit margin compression. Key factors included a drop in feedstock prices, with exceptions such as propylene monomer and benzene; though price corrections were underway for both as availability recovers. An overall underwhelming demand for all resins characterized most of last year, this despite resin suppliers’ efforts to throttle back production, in some cases significantly. Lowered export prices were also underway by fourth quarter due to slowed global demand which indirectly influenced unpublished market discounts domestically.
Polycarbonate prices also appeared to remain flat through part of the third quarter and into the fourth. This after falling a total of 10¢-to- 17¢/lb earlier in the year, according to RTi’s Kallman. He ventures that prices for January would be lower, again as 2024 contract negotiations were underway, with buyers having the leverage. “Demand has been overall static and there is not much optimism for an uptick in demand within first quarter of 2024. Supply has been relatively ample and includes well-priced PC imports.
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.

Because of the growth of the plastics industry, there has been an uptick in number of new hires for processing plastics over the last few years. With new employees comes the challenge of training—not only on company policies and processing duties, but on safety. With that in mind, this column will focus on a topic I feel does not get sufficient attention. In fact, it is a topic on which most of us do not have all the details needed. In my experience, searches on the internet certainly proved inadequate. That topic is the mixing of different resins in the barrel, hot runners, and hot tips.
Exhibitors and presenters at the plastics show emphasized 3D printing as a complement and aid to more traditional production processes.
Polypropylene prices in November moved up once again by 5¢/lb in step with propylene monomer, according to PCW’s Barry, Spartan Polymers’ Newell, and The Plastic Exchange’s Greenberg. As for the December-January time frame, these experts somewhat differed slightly in their predictions, all of which was based on how quickly monomer supplies recovered. All, however, project that barring a major disruption event, that some correction was underway for propylene monomer.
