News in long-fiber thermoplastics at NPE.

At NPE next month, at least two materials suppliers will be featuring new developments in long-fiber thermoplastic (LFT) compounds. PolyOne Corp. of Cleveland has just launched its first products of this type, called OnForce LFT (photo). The company says they are optimized for surface finish, stiffness, and toughness to provide better performance and aesthetics than competing LFT compounds.

OnForce LFT is currently based on PP, nylon 66, and TPU with glass or carbon fibers. PPA and PPS grades are in development for higher-heat applications. OnForce LFT can be supplied with customized fiber loadings, stabilization, colors, and additive packages.

Meanwhile, SABIC Innovative Plastics, Pittsfield, Mass., will be highlighting its Stamax long-glass PP compounds for automotive uses. SABIC, returning to NPE after the absence of its predecessor, GE Plastics, from the last show in 2003, had produced Stamax only in Europe but introduced it here last September. Now, SABIC has secured U.S. production of Stamax by acquiring the RheMax product line from RheTech, Inc. of Whitmore Lake, Mich. RheTech has been licensed since 2005 to use proprietary Owens Corning technology to produce RheMax, while SABIC was licensed to use the same technology to produce Stamax in Europe. Now, RheTech will be the domestic toll producer of Stamax for SABIC.

Other news from SABIC at the show will include new LNP compounds reinforced with natural fibers; new Ultem polyetherimide (PEI) resins, films, and fiber/foam composites; new HDPE natural and black precompounded resins for pressure pipe, and new PC blends that can eliminate some hard-coating steps.

And PolyOne will also introduce at the show GLS TPEs with "universal" nylon overmolding capabilities. GLS Thermoplastic Elastomers, McHenry, Ill., a PolyOne business, just received a patent on "universal polyamide overmolding TPEs" based on GLS's Versaflex alloy technology, which encompasses three chemistries--styrenic block copolymers, olefinic TPVs, and TPUs. The new TPEs are said to bond consistently to any type of nylon, regardless of additives such as glass fiber.
