XPE stands for chemically crosslinked polyethylene foaming material. With high pressure and low density polyethylene resin plus crosslinking agent and foaming agent through high temperature continuous foaming, compared with EPE (physical foamed polyethylene, commonly known as pearl cotton), the tensile strength is higher, the bubble hole is thinner. XPE foaming material is a kind of high-density foaming, surface crust, airtight bubble structure, low water absorption, low thermal conductivity, can do sound insulation, shock absorption, waterproof, mildew proof, suitable for all kinds of wet environment. XPE chemical stability, not easy to decompose, odorless, good elasticity, is the manufacturing of crawling mat, sound insulation layer, heat insulation layer, car floor MATS preferred material. XPE is also an ideal material for automobiles, air conditioners and heat insulation. In recent years, it has developed rapidly in the sports and leisure products market, such as surfboards, karate MATS, yoga MATS and so on. XPE foam, as a new material, also has a certain use in construction. It can be used as floor insulation and shock absorption pad, pipe insulation and noise reduction anticorrosive material, floor heating insulation and sound insulation pad, leakproof and moisture-proof building material, and reflective insulation material for roof and wall. It has a wide range of uses.
