HDPE (High Density Polyethylene) has a continuous use temperature range of -50° F (-46° C) to 180° F (82° C). It is a standard material, and offers high impact strength, high chemical resistance, and very low water absorption. HDPE offers strength and rigidity for many applications requiring basic engineering plastic performance. In all its forms, HDPE is highly processable and can be worked by cutting, drilling and routing. Common brands include Proteus, Densetec, Prime and Polystone.
