Evonik VESTAKEEP® 4000 GF30 black Glass Fiber Reinforced PEEK
Categories:	Polymer; Thermoplastic; Polyketone; Polyetheretherketone (PEEK); Polyetheretherketone, PEEK, Glass Fiber Filled
Material Notes:	VESTAKEEP® 4000 GF30 black is a glass fiber reinforced (30%) polyether ether ketone for injection molding. The semi-crystalline polymer features superior mechanical, thermal, and chemical resistance. Parts made from VESTAKEEP® 4000 GF30 black are self-extinguishing. VESTAKEEP® 4000 GF30 black can be processed on common injection molding machines for thermoplastics. VESTAKEEP® 4000 GF30 black is supplied as cylindrical pellets in 25kg boxes with moisture-proof polyethylene liners. Pigmentation may affect the values. 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.
