XPE foam is produced by compounding PE with some special padding and foaming material, then cross-linking by foaming. The XPE foam is a kind of polymer material with good and independent obturator foramen, and smoothly surface and good elasticity, meanwhile it is also full of high mechanics intensity and good heat
insulation, good waterproof, well resistant to aging, to high temperature, to chemical corrosion and different
environments. The XPE foam can be processed, easy and complex ones are both ok, or it also can
becompounded with some other material to conglutinate.
