1 EPE， It refers to foamed polyethylene, commonly known as pearl cotton. It is a new type of environmentally friendly packaging material. It is composed of countless independent bubbles generated by physical foaming of low-density polyethylene grease. It can be extruded or foamed into shape, and can be made into sheets or pipes, which can then be stamped, cut, and bonded into shape. It has good toughness, is not easy to break, and has good cushioning performance.
2 EPP， Polypropylene plastic foam material is a highly crystalline polymer material with excellent performance, and its unique and superior properties have become the fastest growing environmentally friendly new type of compression buffering and thermal insulation material. EPP products have excellent seismic and energy absorption performance, high recovery rate after deformation, good heat resistance, chemical resistance, oil resistance, and thermal insulation. In addition, their lightweight can significantly reduce the weight of items.
3 EPS， Polystyrene is made through processes such as pre development, curing, molding, drying, and cutting. It can not only be made into foam plastic products with different densities and shapes, but also produce foam plates with different thicknesses. Widely used in construction, insulation, packaging, refrigeration, daily necessities, industrial casting and other fields.
4 EPO， Expanded polystyrene polyethylene mixture is a "copolymer" produced by a special polymerization process, with a unique composition and structure, consisting of 30% polyethylene and 70% polystyrene.
Additional Information:
EPE features: low density, good flexibility, high recovery rate; Better shock resistance than polystyrene plastic; Having an independent bubble structure and low surface water absorption rate; Good anti-seepage performance; Acid, alkali, salt, oil and other organic solvents corrosion resistance, excellent aging resistance.
It does not flow at high temperatures and does not crack at low temperatures. b. Applications: High end furniture, household appliances, instruments and meters, craft gifts, wooden products, glass ceramics, building waterproofing, carpet interlayers, sound insulation, travel bags, precision spare parts, various pipeline insulation and other fields.
The application fields of EPP are becoming increasingly widespread. EPP has been widely used as packaging material for IT products, electronic communication equipment, LCD displays, plasma TVs, precision electronic components, and precision instruments and meters. Another particularly important application area is the extensive use in the automotive industry: car bumpers.
Car side shock absorbers, car door shock absorbers, advanced safety car seats, child safety seats, toolboxes, trunk, armrests, floor mats, sun visors, instrument panels, etc. (According to statistical data, the average plastic used in each car is 100-130kg, of which about 4-6kg is EPP plastic).
