In modern manufacturing and packaging, there are several common foam materials that play an important role in their respective fields of application. This article will introduce the characteristics and applications of materials such as EPP, EPE, EPS, EPO and ETPU.

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

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 compression buffer and heat 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, molding, 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. EPE, which refers to expanded polyethylene, also 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, which can then be stamped, cut, and bonded to form. It has good toughness, is not easy to break, and has good cushioning properties.

5. ETPU is a thermoplastic elastomer material with soft texture, excellent elasticity, wear resistance, tear resistance and anti-slip properties. It is widely used in the field of shoe materials. It is not only suitable for making midsoles and insoles of sports shoes, but also It is suitable for use in many fields such as repeated impact resistance, sports protection, damping, household products, low-load pneumatic tires, etc.

Notice: EPP machines can make EPS, EPP, EPO, and EPE; they cannot make ETPU. ETPU machines can make products made of all other materials.
