Evonik VESTAKEEP® 1000 G Polyetheretherketone (PEEK)
Categories:	Polymer; Thermoplastic; Polyketone; Polyetheretherketone (PEEK)
Material Notes:	Low- viscosity, unreinforced polyether ether ketone VESTAKEEP® 1000G is a low-viscosity, unreinforced polyether ether ketone for injection molding. The semi-crystalline polymer features superior, thermal and chemical resistance. Parts made from VESTAKEEP® 1000G are self-extinguishing. VESTAKEEP® 1000G can be processed by common injection machines for thermoplastics. VESTAKEEP® 1000G is supplied as granules in 25 kg boxes with moisture-proof polyethylene liners. Property data for dry samples. Information provided by Evonik.
Vendors:	Ensinger TECAPEEK™ shapes are manufactured exclusively with Victrex™ PEEK polymer. The Ensinger process and Victrex resins ensure reliability, consistency, dimensional stability, and high temperature mechanical performance.
