Resist wear foam pyramid microwave absorber for anechoic chamber
Good thermo stability. EPE has the temperature resistance of 70-80℃, EPS is less than 80℃, while EPP can withstand over 120℃. Moreover, EPP has less than 2% shrinkage at 120℃ over 22h. Good mechanical property. EPP with density of 0.035g/cm 3 has tensile strength of 0.56MPa and 0.38MPa at longitudinal direction and transverse direction, respectively. Good environmental friendly. Compare with PU, EPP doesn’t yield harmful isocyanate residue and the base material can be recyclable. Compare with EPS and EPE, EPP doesn’t use hydrochlorofluorocarbon (HCFC) or butane in foaming process, so that the material has no bad effect on environment after degradation.
