VESTAKEEP® 5000 G

Chemical Family: Polyether Ether Ketone (PEEK)

VESTAKEEP® 5000 G is a high-viscosity, unreinforced polyether ether ketone suitable for injection molding and extrusion. It is a semi-crystalline polymer with superior thermal and chemical resistance. Parts made from VESTAKEEP® 5000 G have low flammability and can be processed using standard machines for thermoplastics.

Processing: VESTAKEEP® 5000 G 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. VESTAKEEP® 5000 G possesses an impact strength that is about 20 percent higher than any previously used PEEK grade and can therefore be used even where other PEEK grades fail.
Shelf LIfe: 2 years
Flame Rating: IEC 60695-11-10 V0
Technology: Plastics
Packaging Type: Boxes
Benefits: VESTAKEEP® 5000 G are suitable for convoluted and corrugated tubes. The high temperature resistant PEEK is inherently flame retardant, has a high LOI, a low smoke density, and releases no toxic gasses in case of fire.. Evonik's high-performance polymers VESTAKEEP® 5000 G can be used as liners for down- hole tubing in injection and production wells under demanding conditions that include High Pressure High Temperature (HPHT) and chemical resistance.
