On market, almost all of the plastic pallet is PP (polypropylene) and PE (polyethylene) to carry on the processing of raw materials production, the primary difference between PP and PE plastic pallet is the low temperature brittleness, PP material of the plastic pallet prone to fracture in low temperature, and PE material because of its material hard for plastic pallet, Fracture is less likely to occur at low temperatures. PP is not cold resistant, PE is not fall resistant.Shandong Liyang Plastic Molding Co., Ltd. plastic pallet HDPE (high density polyethylene) adopted by the material in ordinary PE material on the basis of improving the raw material of cold resistant, good low temperature resistance, resistance to impact, so that produce plastic pallet is on the market longer service life of ordinary plastic pallet, but absolutely, green environmental protection, economical and practical.
