VESTAKEEP® L4000G
聚醚醚酮
High-viscosity, unreinforced polyether ether ketone
VESTAKEEP L4000G is a high-viscosity, unreinforced lubricated polyether ether ketone for injection molding and extrusion.
The semi-crystalline polymer features superior thermal and chemical resistance. Parts made from VESTAKEEP L4000G are self extinguishing.
VESTAKEEP L4000G can be processed by common machines for thermoplastics.
The additional lubrication agent improves the feeding process.
