We often use the EPP, EPS and EPE in the packaging. But, what’s the difference between eps,epp and epe?

EPP: polypropylene foam material is a kind of high performance and high crystalline polymer materials, special and superior performance to become the fastest growing environmental protection new compression buffer insulation materials. EPP products has very excellent seismic energy absorption performance, high response rates after deformation, good heat resistance, chemical resistance, oil resistance, insulating and stays in addition, the quality is light, can significantly reduce weight.

EPS, due to its good buffer performance and vibration absorption performance to become the modern use of buffer material. EPS has light weight, easy processing and good protection performance, the advantages of the wide adaptability, quality and cheap, but there are not natural weathering, large volume, waste incineration will produce harmful gases, etc. In serious pollution of the environment and natural resources under the condition of EPS aroused people's great attention to the harm of environment. So the foam will gradually be replaced by other environmental buffer materials.

EPE pearl cotton is a foam cushion, aseismic capacity of environmental protection materials, it is soft, light, flexible, can bend to absorb and disperse the external impact force, overcome the ordinary Styrofoam fragile, deformation, the poor resilience. At the same time, EPE has the thermal insulation, moisture-proof, sound insulation, friction, anti-aging, corrosion resistance and a series of the use of superior features. To join the special material, EPE pearl cotton, has significant antistatic performance. It is also a kind of environment-friendly materials can be recycled. Pearl cotton protection of edge horn is widely used in construction, mechanical and electrical engineering, high-grade furniture, household appliances, instruments and meters, craft gifts, wood products, glass ceramics, carpet mezzanine, travel bags, packaging and insulation in areas such as precision spare parts.

Actually used by three kinds of materials are packaging materials, the main difference is the different chemical composition.
