At present, the main forming foams on the market mainly include EPS, XPS and EPP, but many people do not understand the difference between them. Today Dongguan Foam Factory takes you to understand the difference between EPS, XPS and EPP:
1. EPS molding foam, also known as polystyrene foam, has the special effects of light weight, heat insulation, sound absorption and shock absorption. Mainly used in packaging industry and external wall insulation industry.
2. XPS foam is also called extruded polystyrene foam. Compared with EPS foam, XPS foam has the characteristics of high density, high compression performance, small thermal conductivity, low water absorption, and small water vapor permeability coefficient. In the long-term high humidity or immersion environment, XPS board can still maintain its excellent thermal insulation performance. Among various commonly used thermal insulation materials, it is currently the only thermal resistance retention rate that is still above 80% after 70% relative humidity for two years. Insulation material. The disadvantage is that it is not easy to paste, and the price is higher than EPS foam.
3. EPP foam, also known as expanded polypropylene foam, is titled as a new molded foam. EPP has light specific gravity, good elasticity, strong shock and compression resistance, high deformation recovery rate, good absorption performance, oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, no water absorption, insulation, and heat resistance. EPP is mainly used in the automotive industry and packaging industry.
