We’ve been reporting on rising prices of all commodity resins, including engineering resins ABS, PC, nylons 6 and 66, as well as key additives through first quarter. Generally, higher energy and raw material prices have been cited as the key contributing factors. Still, the nuances of the high-volume PE and PP markets make the pricing movements of these resins particularly intriguing, if not vexing.

Checking in with our sources at Houston-based PetroChemWire (PCW) as March comes to a close, we get an interesting scenario of how things might shape up in April and the second quarter, overall. Here’s where things are these days:

One day before the conference kicked off, Scientific Molding expert, and PT columnist, John Bozzelli held a special sold-out training event at the Polymers Center of Excellence in Charlotte. Using a mold and material supplied by John McDonnell and Nexeo Solutions. Assisting Bozzelli at the press was the Polymers Center’s Amanda Hurd.

Always challenging his students, Bozzelli offered praise (tossing candy underhand for correct answers) and used data to debunk some molding misconceptions. By the second half of the class, and after a tour of the center, Bozzelli’s tie came off as he pressed the class through the lesson.

Two companies have just unveiled their latest developments in high-performance materials for additive manufacturing and, as we reported recently, the materials continue to evolve and impress.

DuPont Performance Materials: At the recent 2017 Additive Manufacturers User Group (AMUG) conference and expo in Chicago (March 19-23), showcased new high-performance materials in filament forms of Zytel nylons, Surlyn ionomers and Hytrel thermoplastic elastomers. They are designed for the FFS (fused filament fabricaton) process, also referred to as FDM (fused deposition modeling).

Within this first quarter, we’ve been reporting on price increases underway for virtually all commodity resins, including commodity engineering resins ABS, PC, nylons 6 and 66 (as well as price increases in plastics additives). In many of these cases, the key factor cited has been increases in raw materials.

We are now alerted to price increases of some specialty engineered resins underway for second quarter, including polyacetals (POM), for which key applications include high-performance engineering components such as small gear wheels, eyeglass frames, ball bearings, ski bindings, fasteners, guns, knife handles, and lock systems.
