Product Texts
Glass fiber-reinforced (30%), medium viscosity polyether ether ketone
VESTAKEEP®2000 GF30 is a medium-viscosity, 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® 2000 GF30 are of low flammability.
VESTAKEEP® 2000 GF30 can be processed by common injection-molding machines for thermoplastics.
We recommend a melt temperature between 380°C and 400°C during the injection molding process. The mold temperature should be within a range of 160°C to 200°C, preferably 180°C.
VESTAKEEP® 2000 GF30 is supplied as cylindrical pellets in 25kg boxes with moisture-proof polyethylene liners.
Pigmentation may affect values.
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.
For information about processing of VESTAKEEP 2000 GF30, please follow the general recommendations in our brochure “VESTAKEEP® PEEK Processing Guidelines“.
