anti-UV hardness hdpe pad for ballistic laminate
anti-UV hardness hdpe pad for ballistic laminate
HDPE is a non polar thermoplastic plastic with high crystallinity and perfect electrical properties,especially the high insulation dielectric strengh.This polymer is non-hygroscopic which can be used to packing with good waterproof steam.HDPE with Middle to high molecure weight have good impact resistance at normal temperature even in the zero 40 degree Celisius.

main properties:
•high insulation dielectric strength
•perfect impact resistance
•good heat /cold endurance
•no toxic
•excellent chemical resistance
•low water absorption
•good temperature properties
