LOW DENSITY POLYETHYLENE (LDPE), commonly known as high-pressure POLYETHYLENE, is mainly used in plastic bags and agriculturalfilm 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 lowntemperature toughness, high modulus, bending resistance and stress cracking resistance, and good impact strength at low temperature.
High density polyethylene resin can be injected, extrusion, blow molding and rotary molding methods to form plastic products. Various types of containers, industrial accessories, medical supplies, toys, shells, stoppers and shields can be formed by injection molding. Various hollow containers and ultra-thin films can be formed by blow molding. Using extrusion molding molding pipe, stretch strip, binding tape, monofilament, wire and cable sheath.
In addition, it can also form decorative panels, blinds, synthetic wood, synthetic paper, synthetic film and formed calcium-plastic products.
