PE shrink film properties and uses of raw materials introduced

1. LDPE (high-pressure low-density polyethylene): its products with low density, good transparency, good insulation, etc., mainly used for plastic sheeting (film, film), heavy packaging film, shrink film, Materials and cable sheathing production, can also be used for injection molding, extrusion, foam and other processing areas.
Product physical and chemical properties: non-toxic, tasteless, surface sheen of milky white cylindrical particles, with good elongation, electrical insulation, the degree of 55-65% crystallinity, crystal melting point of 108-126 ℃.
2. HDPE (low-pressure high-density polyethylene):
Product physical and chemical properties: non-toxic, tasteless, odorless white particles, the melting point of about 130 ℃, the relative density of 0.941-0.965. Has good heat resistance and cold resistance. Chemical stability, high rigidity and toughness, good mechanical strength, dielectric properties, resistance to environmental stress cracking performance is also good.
3. LLDPE (Linear Low Density Polyethylene):
Product physical and chemical properties: non-toxic, tasteless, odorless milky white particles, the relative density of 0.918-0.939. Compared with LDPE has high strength, good toughness, rigidity, heat, cold, etc., also has good resistance to environmental stress cracking, tear strength and other properties, and acid, alkali, organic solvents.
