Medium Density Polyethylene (MDPE) is produced in a low pressure rector and is defined as having a density between 0.930 and 0.940 g/cm3. MDPE offers a good balance of strength, stiffness, and toughness and is most often used for rotational molding. MDPE grades for rotational molding will normally contain additional anti-oxidants and UV stabilizers in their formulation. Common rotational molded applications include playground equipment, storage tanks, large bins, portable barriers, carts, toys and sporting goods.
