Character: Nontoxic, low-temperature resistance, chemical stability, water absorption, electric insulation. As one of engineering plastic, HDPE is well know for their marked thermal-stability, excellent mechanical properties.
Application: It can be used as the material of food machine components, insulation and soundproof materials, or be used to make the accessories for the anti-erode machines.
