| High-viscosity, unreinforced polyether ether ketone VESTAKEEP 5000G is a high-viscosity, unreinforced polyether ether ketone for injection molding and extrusion. The semi-crystalline polymer features superior thermal and chemical resistance. Parts made from VESTAKEEP 5000G are selfextinguishing. VESTAKEEP 5000G can be processed by common machines for thermoplastics. We recommend 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.&& |
