Evonik VESTAKEEP® L 4000 G PEEK
Categories:	Polymer; Thermoplastic; Polyketone; Polyetheretherketone (PEEK); Polyetheretherketone, PEEK, Unreinforced
Material Notes:	VESTAKEEP® L 4000 G is a high viscosity, unreinforced lubricated polyether ether ketone for injection molding and extrusion. The semi-crystalline polymer features superior, thermal and chemical resistance. Parts made from VESTAKEEP® L4000G are of low flammability. VESTAKEEP® L 4000 G can be processed by common machines for thermoplastics. The additional lubrication agent improves the feeding process. The manufacturer recommends a melt temperature between 370°C and 380°C during the injection molding process. The mold temperature should be within a range of 160°C to 200°C, preferably 180°C. VESTAKEEP® L 4000 G is supplied as granules in 25 kg boxes with moisture-proof polyethylene liners. Inside the original and undamaged packaging, the product has a shelf life of at least 2 years when stored in dry rooms at temperatures not exceeding 30°C. Pigmentation may affect values. Dry properties listed below Industrial Sector: Automotive and Mobility, Energy, Oil and Gas Processing: Injection molding, Extrusion Delivery form: Pellets, Granules Conformity: Food contact Additives: Unfilled Applications: Electrical and Electronical Processing: Film extrusion, Profile extrusion Information provided by Evonik.
