產(chǎn)品說明:
Medium-viscosity, unreinforced polyether ether ketone
VESTAKEEP 2000G is a medium-viscosity, unreinforced polyether ether ketone for injection molding.
The semi-crystalline polymer features superior thermal and chemical resistance. Parts made from VESTAKEEP 2000G are self-extinguishing.
VESTAKEEP 2000G can be processed by common injection molding machines for thermoplastics.
We recommend a melt temperature between 360°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.
