What are EPE, EPP, EPS and EPO materials respectively?
1, EPE, it refers to foamed polyethylene, which is often referred to as pearl cotton. It is a new type of environmentally friendly packaging materials. It consists of polyethylene resin by physical foaming to produce numerous bubbles. It can be extruded or foamed, and can be made into sheets or plates or tubes, and then pressed and cut and bonded into shape, good toughness, not easy to break, good buffering performance.
2, EPP, a high crystalline polymeric material with good performance, special and superior performance has become a fast-growing new environmental protection anti-pressure cushioning and heat insulation material. epp products have excellent shock absorption performance, high recovery rate after deformation, good heat resistance, chemical resistance, oil resistance and heat insulation. In addition, they are light in weight and can greatly reduce the weight of items.
3, EPS foam machinery, polystyrene, is made by the process of prefermentation, maturation, molding, drying and cutting. It can be made into foam products of different densities and shapes, and can also produce a variety of different thicknesses of foam sheets. It is widely used in construction, insulation, packaging, refrigeration, daily necessities, industrial casting and other fields.
4, EPO, expanded polystyrene polyethylene blend, it is a special polymerization process to produce a “copolymer”, the composition and structure is unique, composed of 30% polyethylene and 70% polystyrene.
