产品说明:
High-viscosity, unreinforced
polyether ether ketone
VESTAKEEP 5000G is a high-viscosity, unreinforced polyether ether ketone for
injection molding and extrusion.
The semi-crystalline polymer features superior thermal and chemical resistance.
Parts made from VESTAKEEP 5000G are selfextinguishing.
VESTAKEEP 5000G 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.
