Analysis of impact resistance of EPP foam

There are many kinds of EPP foam products, including EPP toys, EPP heat insulation panels, EPP car bumpers, EPP car seats and so on. Especially in the automobile industry and packaging industry, there are high requirements for the strength and impact resistance of materials. Why can foamed polypropylene be widely used in these two industries? Let's take a look at the impact resistance advantage analysis of foamed polypropylene.

EPP has high compressive strength and can withstand 42.7kpa, higher than graphite EPS (20kpa) and rubber foam (25kpa). The elastic modulus of 0.45MPa is higher than that of polyethylene crosslinked foam and rubber plastic foam, and is better in all foam materials. In the packaging industry, the protection effect is excellent. It is not afraid that the goods will be squeezed during transportation and cause product damage.

The compressive creep of EPP is only 0.6%, which means that when it is subjected to large pressure and impact, the expanded polypropylene will only deform slightly. However, commonly used materials such as polystyrene 55%, polyethylene crosslinking, rubber and plastic 20%, and expanded polypropylene have better deformation and impact resistance than all materials. It will return to its original state after continuous impact. Used in cars can effectively protect passengers and pedestrians.

EPP has good elasticity, high compressive strength and safer use. Especially in the automotive industry, it also has a good protective effect on the packaging and preservation of goods.

EPP can achieve different functions through different production processes and additives, and anti-static packaging is one of them. Generally, EPP anti-static packaging is used for electrical and electronic products to prevent damage to electronic components. EPP anti-static packaging is mostly black. The functions and effects of EPP products can be distinguished by color.

Compared with ordinary foamed plastics, EPP products can achieve the effect of antistatic. In addition to antistatic, other properties such as anti-collision and anti falling are better than other types of materials. EPP products have obvious advantages in packaging protection of electronic appliances and other precision components. The advantages of physical and chemical protection performance and unique degradable environmental protection advantages make EPP anti-static protection become the mainstream of electronic product packaging.

Anti static packaging is mostly used in various precision products such as electronic appliances. Some high-precision instruments such as cameras and measuring instruments have high requirements for static electricity. In order to prevent the damage of static electricity to components, EPP anti-static packaging is adopted, which has high anti-static protection and obvious effect.
