PET board or PET-P board, poly terephthalic acid type plastic, polyester board for short. It is mainly made of polyester raw materials through high temperature extruder.Extrusion, through different caliber grinding tool mouth extrusion and get different thickness of the plate. Ingredients mainly include PET and PBT resin. Poly terephthalate ethylene glycol ester is commonly known as polyester resin, commonly known as polyester resin. It is a polycondensation of terephthalic acid and ethylene glycol, and imported PET board PBT together collectively known as thermoplastic polyester, or saturated polyester. At present PET and PBT together as thermoplastic polyester, become one of the five major engineering plastics.
