EPP (Expanded polyproplene)

Is a high-performance crystalline polymer / gas composite materials, with its unique and superior performance as environmental protection is currently the fastest growing new compression buffer insulating material. EPP products have a very excellent shock absorbing properties, deformation after the response rate, good heat resistance, chemical resistance, oil resistance and heat resistance, in addition, its light weight, can significantly reduce the weight of items. EPP is an environmentally friendly material, not only recyclable, and can naturally degrade and will not cause white pollution.

1.EPP performance characteristics
⑴ energy absorption: As the EPP foam products have a special structure, through the foam in the gas stagnation and compression effect to absorb the energy dissipation, has excellent compression energy absorption performance. Widely used in automotive bumper energy processing systems and other anti-collision energy-absorbing components.
⑵ size shape recovery Stability: EPP products by successive deflection after impact and restore the original shape immediately, without causing deformation, has a "memory" capability.
⑶ strong heat resistance: EPP products with temperature up to 130 ℃.
⑷ good low temperature properties: EPP products even at -30 ℃, also showed good performance. Therefore be used as a high thermal insulation material.
⑸ suitable for repeated use: EPP products, flexibility, and can be used repeatedly, not broken.
⑹ light weight: EPP products have a very light quality can greatly reduce the weight, can be used in aircraft, automobiles and other important parts.
⑺ has a good surface protection: EPP products are semi-rigid shape, with moderate hardness, softness, no scratches, bumps in contact with objects, with good surface protection.
⑻ good insulation: EPP products, independent cell structure, showing a low thermal conductivity, it has excellent.
⑼ permeability is small, the buoyancy is good: As the EPP's closed-cell structure, its products have excellent long-term floating and the water permeability is small, or even placed in salt water does not diminish its buoyancy.
⑽ oil, good chemical resistance: chemically inert because of EPP, making its products oil resistance, good chemical resistance.
⑾ reusable eco-friendly materials: easy recycling, decomposition, product does not contain harmful toxic ingredients, combustion does not produce toxic substances.
⑿ good stability in different environments: EPP products have excellent durability, such as UV exposure, physical damage, extreme temperatures (-30 ℃ ~ 130 ℃), abrasion and other harsh environments!
