WEB EXCLUSIVE: Evonik Industries (U.S. office in Parsippany, N.J.) is developing a new engineering polymer that surpasses the performance of existing PEEK materials in high temperatures and extreme environments. Through a joint collaboration with Greene, Tweed of Kulpsville, Pa., this effort combines Evonik’s expertise in materials development with Green, Tweed’s proficiency in manufacturing custom polymeric stock shapes and components for demanding applications.

Built on Evonik’s Vestakeep PEEK platform, the new material is said to have significantly improved mechanical properties above 350 F and 15,000 psi, with chemical resistance comparable to standard PEEK. Enhanced creep and extrusion resistance over existing thermoplastic is also claimed. Dynamic Mechanical Analysis (DMA) results show superior mechanical property retention at temperatures from 350 F to 600 F. In extrusion testing at 35,000 psi and 555 F, it outperforms other filled and unfilled PEEK compounds.

    Though often criticized, MFR is a very good gauge of the relative average molecular weight of the polymer. Since molecular weight (MW) is the driving force behind performance in polymers, it turns out to be a very useful number.
