Higher-performance and easier processing PE film resins for packaging, a one-pass crosslinked PE for photovoltaic (PV) wire and cable, several higher-performing nylons and TPEs, “greener” plastics, and enhanced styrenic and PC resins are among the new materials that made their debut at the big show in Orlando, Fla., last month.

Last fall’s K 2010 fair in Germany drew dozens of materials suppliers to show off hundreds of new products, aimed especially at packaging,medical, automotive, and electrical/electronics.

This first of two articles on directions in TPE development focuses on styrenic, copolyester, polyamide, and TP urethane elastomers. The following article covers olefinics—TPOs, TPVs, and POEs.

Nylon producer Ems-Grivory America in Sumter, S.C., is reaching beyond its traditional product range to bring out new partially aromatic nylons that bridge the gap between standard engineering thermoplastics and high-performance specialty polymers.

 Higher flow, higher heat, higher barrier, higher clarity, higher stiffness, lower durometer, lower smoke, lower odor—materials exhibits at the recent K 2004 show in Dusseldorf were stretching the bounds of processing and performance properties in all directions.

Usage of polyamides in U.S. under-hood parts could double in the next decade if nylon 6 and 66 follow European trends toward large panels that not only protect but beautify the engine compartment.

NPE 2000 saw the debut of many new nylons, ranging from 6 and 66 types that are tougher, easier to process, and lower in density to a brand-new class of branched nylons with outstanding physical and rheological properties and a long-carbon-fiber grade that combines high electrical shielding with flame retardance.Also new at the show were extrusion-grade and reinforced PPS, new PPS alloys, and new sources of high-heat, reinforced polyphthalamide, PEEK, and syndiotactic polystyrene compounds.

New materials at NPE 2003 target automotive, appliance, and packaging sectors. Engineering thermoplasticsdominate the news, but there were also severalnew TPEs and a few polypropylene introductions.

Thermoplastic polymer-bonded magnets are exerting a stronger pull on designers of motors, valves, sensors, and other electronic devices used in cars, telecommunications devices, and large appliances. The attraction is strongest in applications demanding greater design freedom than is offered by conventional magnets sintered from 100% metal powder.
