Ultra High Molecular Weight Polyethylene Plastics

Introduction of the product Classification of Polyethylene Polyethylene can be classified into high-density polyethylene (HDPE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE) and ultra-high molecular weight polyethylene (UHMWPE) according to the method of polymerization, molecular weight and chain structure. LDPE Properties: tasteless, odorless, non-toxic, non-glossy surface, milky white waxy particles, density of about 0.920 g/cm3, melting point 108 ℃ ~ 126 ℃. Insoluble in water, slightly soluble in hydrocarbons and so on. It is resistant to the erosion of most acids and alkalis, with small water absorption, and can still maintain softness at low temperature, with high electric insulation. Production process: there are mainly two kinds of high-pressure tube method and kettle method. In order to reduce the reaction temperature and pressure, the tube method process is commonly used in low-temperature, high-activity initiator initiated polymerization s…
