PET foam core material has good shear properties, so it is often used as a shear-resistant filler in shell structures. The cost of PET raw materials is lower than that of common core foam materials. PET is environmentally friendly.
PET can withstand a temperature of about 150°C for a short time during the processing. Its highest long-term working temperature is 100°C.
