EPP (foamed polypropylene) and ordinary PP materials contrast

EPP (foamed polypropylene) is a lot of advantages compared to ordinary foamed plastic and polypropylene foam material.:
1) the rigidity of polypropylene (PP) is better than that of PE, and the bending modulus of PP is about 1.52Gpa, the PE is only 207Mpa, and the chemical resistance is similar with PE..
2) the glass temperature of polypropylene is lower than that of room temperature, the impact resistance is better than that of PS, and it is hard to recover the PS foam, and the polypropylene foam is a kind of environmentally friendly material..
3) polypropylene has high thermal deformation temperature, and can be applied in some high temperature fields.. High temperature foamed polypropylene usually 130 degrees, than the maximum use temperature of 80 DEG C higher polyethylene foam. The thermal conductivity of a closed cell structure can not be affected by moisture, so it can be used as heat preservation material..
4) good low temperature characteristics: the product can show good performance even at -30.
5) energy absorption: because the PP foam products have good absorption energy, and have excellent compressive energy absorption properties. Widely used in automotive bumper energy handling systems and other anti - impact energy - absorbing components.
6) the size of the shape recovery stability: PP foam products by repeatedly impact and bending deformation will soon resume the original shape, without permanent deformation.
7) the quality of light and can be used repeatedly: PP foam density can achieve very low level, so it can greatly reduce the weight, and PP foam products, good flexibility, can be used repeatedly, not easily broken; easily recyclable, easy to decompose. Products not containing the poisonous and harmful composition of human body, combustion does not produce toxic substances.
8) with good surface protection and sound insulation performance: PP foam products is semi hard forming, with moderate hardness, softness, no scratches, bumps in contact with objects, with good surface protective.
