EPP, extruded polypropylene, features excellent heat resistance, dimensional stability, buffer performance, cryogenic property, oil resistance, and chemical resistance. It is also recyclable. These small and black particles of EPP have gone deep into our daily life. They have been utilized in making insoles, food cases, incubators, packages, and so on. Today let’s talk about their particular use in the panels of car parts.
Firstly, the EPP panel is 40%-50% lighter than the polyurethane foam panel in achieving the same effect of energy absorption. It is thus more suitable for car side panels, knee panels, seat frames, and other bumper parts required to be lightweight with high impact resistance.
Secondly, polypropylene foam performs better in heat resistance. It helps a lot in sun visor panels, dashboard panels, and door panels where the temperature tends to rise rapidly.
Besides lightweight and heat resistant, the EPP foam panel is easy for heat welding. It makes the carports, car doors, car roof panels, carpet supports, sound insulation panels, door liners, and luggage racks easy to install. Its good thermal processing property enables its use in central control boxes and shock-proof panels.
With the maturity of EPP technology and the continuous solution of raw material problems, the price of EPP is gradually decreasing. For other applications in various fields, EPP is also believed to have superior performance!
