PET foam material, or polyester resin, is a recyclable thermoplastic polymer foam characterized by a closed-cell structure. It possesses an array of superior qualities such as thermal insulation, smoke prevention, and non-toxicity. Furthermore, it exhibits exceptional mechanical strength and fatigue resistance, chemical stability, UV resistance, and low water absorption. Applications include: packaging boxes, packaging liners, lunch boxes, plates, cosmetic trays, replacing PU polyurethane and fiberglass as the core material in laminated boards for use in car ceilings or home decor wall and floor panels, automotive glass packaging, wind turbine blade filling, aluminum composite panel cores, steel composite panel cores, steel coil transportation packaging, tote boxes, and more.
