PE
Polyethylene can be divided into high density polyethylene, low density polyethylene and linear low density polyethylene according to the polymerization method, molecular weight and chain structure.
LOW DENSITY POLYETHYLENE (LDPE), commonly known as high-pressure POLYETHYLENE, is mainly used in plastic bags and agricultural film due to its LOW DENSITY and the softest material.
HIGH DENSITY POLYETHYLENE (HDPE) is commonly known as low pressure POLYETHYLENE. Compared with LDPE and LLDPE, it has higher temperature resistance, oil resistance, steam permeability resistance and environmental stress cracking resistance. In addition, it has good electrical insulation, impact resistance and cold resistance, which is mainly used in blow molding and injection molding fields.
Linear Low Density Polyethylene (LLDPE) is a copolymer of ethylene and a small amount of advanced olefin in the presence of catalyst.LLDPE is similar to LDPE in appearance, with poor transparency and good surface gloss. LLDPE has the advantages of low temperature toughness, high modulus, bending resistance and stress cracking resistance, and good impact strength at low temperature.
