PE generally refers to polyethylene, which is a thermoplastic resin prepared by polymerization of ethylene.
2. Differences in characteristics
EPE has many advantages, such as waterproof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance and so on, and also has good chemical resistance.
PE has excellent low temperature resistance (the lowest service temperature can reach-100 ~-70 C), good chemical stability and resistance to most acids and bases (not to oxidizing acids). Insoluble in general solvents at room temperature, with low water absorption and excellent electrical insulation.
3, the difference in application
EPE is widely used in automobile cushions, pillows, electronic appliances, instruments, computers, stereos, medical devices, industrial control cabinets, hardware lighting, handicrafts, glass, ceramics, household appliances, spraying, furniture, wine and resin and other high-end fragile gift packaging, hardware products, toys, melons and fruits, leather shoes, daily necessities and other products packaging, as well as express packaging.
PE is suitable for product labels with high water resistance, oil resistance, chemicals resistance, etc. Hanyuan Printing often applies this material to cosmetics, shampoo, washing and other daily chemical labels with moisture resistance and extrusion resistance requirements during use. Polyethylene can be processed by blow molding, extrusion and injection molding, and is widely used in the manufacture of films, hollow products, fibers and daily necessities.
