VESTAKEEP® 4000 GF30 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 are of low flammability.
VESTAKEEP® 4000 GF30 can be processed on common injection molding machines for thermoplastics.
We recommend a melt temperature of 380°C to 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® 4000 GF30 is supplied as cylindrical pellets in 25kg 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 the values.
