Expanded polyolefin foams used in interior soft trim applications

摘要

Polyurethane foams have traditionally dominated the automotive interiors market for both their energy-absorbing characteristics and ability to achieve a soft feel acceptable to occupants. Interest in EPP, EPE, and hybrid polyolefin's for interiors has grown given the increasing demands for occupant safety, lower cost, lower mass, and recyclability. In many cases, the density of the Polyolefin Foam that provides the energy-absorbing characteristics that are being evaluated are considered to be too stiff for occupant comfort.
