LDPE (High Pressure Low Density Polyethylene): Its products have the advantages of low density, good transparency and good insulation. They are mainly used in agricultural film (shed film, mulch film), heavy packaging film, shrink film, transparent film, insulating material and cable. The production of the sheath can also be used in the fields of injection molding, extrusion, foaming and the like.
Physical and chemical properties of the product: non-toxic, odorless, surface-glossy milky white cylindrical particles with good elongation, electrical insulation, crystallinity 55-65%, crystalline melting point 108-126 °C.
HDPE (low pressure high density polyethylene): physical and chemical properties of the product: non-toxic, odorless, odorless white particles, melting point of about 130 ° C, relative density of 0.941 - 0.965. Has good heat resistance and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, dielectric properties, and environmental stress crack resistance.
LLDPE (Linear Low Density Polyethylene): Physical and chemical properties of the product: non-toxic, odorless, odorless milky white particles with a relative density of 0.918-0.939. Compared with LDPE, it has the advantages of high strength, good toughness, strong rigidity, heat resistance and cold resistance. It also has good resistance to environmental stress cracking and tear strength, and is resistant to acids, alkalis and organic solvents.
