VESTAKEEP® 3300G
聚醚醚酮
Evonik Industries AG
產(chǎn)品說明:
VESTAKEEP 3300G is a
medium-viscosity, unreinforced polyether ether ketone for injection molding and
extrusion.
The semi-crystalline polymer features superior thermal and chemical resistance.
Parts made from VESTAKEEP 3300G are self-extinguishing.
VESTAKEEP 3300G can be processed by common 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.
