High Density Polyethylene (HDPE) is a machinable thermoplastic known for its high strength-to-density ratio, long term durability and light weight. Its toughness and flexibility make it one of the most commonly used plastics in the United States today.
HDPE's versatility and high tolerance to many substances and environments alongside a very competitive price make it an outstanding material for a wide variety of applications. HDPE has a low coefficient of friction and can be easily cut, machined, welded, and thermoformed for easy fabrication. HDPE will not splinter, rot or absorb harmful bacteria, and is extremely resistant to cleaning agents.
HDPE is also known by brand names including King Starboard®, King Starlite®, ColorCore®, Proteus®, PE2Print®, Corrtec®, Playboard® and Designboard®.
