What materials are EPP, EPE, EPS and EPO?

1. EPE, which refers to expanded polyethylene, is also commonly known as pearl cotton. It is a new type of environmentally friendly packaging material. It is composed of low-density polyethylene grease that is physically foamed to produce countless independent bubbles. It can be extruded or foamed, and can be made into plates, sheets, or pipes, and then stamped, cut, and bonded to form. It has good toughness, is not easy to break, and has good cushioning properties. ?

2. EPP, polypropylene plastic foam material, is a highly crystalline polymer material with excellent performance. Its unique and superior performance has become the fastest growing new environmentally friendly pressure-resistant buffer insulation material. . EPP products have excellent shock-resistant energy-absorbing properties, high recovery rate after deformation, good heat resistance, chemical resistance, oil resistance and heat insulation. In addition, their light weight can greatly reduce the weight of items. ?

3. EPS, polystyrene, is made through processes such as pre-expansion, curing, shaping, drying and cutting. It can not only make foam plastic products of different densities and shapes, but also produce foam boards of various thicknesses. It is widely used in construction, insulation, packaging, refrigeration, daily necessities, industrial casting and other fields. ?

4. EPO, a mixture of expanded polystyrene and polyethylene. It is a "unpolymer" produced by a special polymerization process. It has a unique composition and structure and is composed of 30% polyethylene. Made of 70% polystyrene.

Extended information:

EPE features: low density, good flexibility, high recovery rate; shock-proof performance is better than polystyrene plastic; it has an independent bubble structure and low surface water absorption ; Good anti-penetration performance; resistant to acid, alkali, salt, oil and other organic solvent corrosion, and 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, wood products, glass ceramics, building waterproofing, carpet interlayers, sound insulation, travel luggage, precision spare parts, various pipe insulation and other fields.

EPP application fields are becoming more and more extensive. IT products, electronic communication equipment, liquid crystal displays, plasma color TVs, precision electronic components, precision instruments, etc. have begun to use EPP as packaging materials in large quantities. Another particularly important area of ??application is the numerous applications in the automotive industry: car bumpers.

Car side shock-proof cores, car door shock-proof cores, advanced safety car seats, child safety seats, tool boxes, trunks, armrests, bottom pads, sun visors, instrument panels, etc. (according to statistical data Reflection: Currently, each car uses an average of 100~130kg of plastic, of which about 4~6kg is EPP plastic).
