The Plate is made from UHMWPE (Ultra-High Molecular Weight Polyethylene), a very tough material with the highest impact strength of any thermoplastic currently produced. Our UHMW tape protects surfaces from abrasion and creates a "slip plane" effect to allow contact without wear. The tape reduces squeaks, rattles and other noises that can occur with movement of touching surfaces. HDPE (High Density Polyethylene) has a somewhat lower tensile strength than UHMW. It possesses excellent chemical resistance and low moisture absorption. HDPE is used in a variety of applications and industries where impact resistance, high tensile strength, low moisture absorption and chemical and corrosion resistance properties are required.
