Ultra High Molecular Weight Polyethylene (UHMWPE) and High-Density Polyethylene (HDPE) are both extremely tough plastics with high wear and abrasion resistance. UHMWPE is a very hard-wearing and low-cost material. With it's resistance to corrosive materials and high impact strength, it's well-suited to wet environments and is an excellent choice of base material for a variety of industries, including energy production. Often used for simple things like chain tensioner blocks and other mechanical wear components, these physical properties make the material ideal for many sealing applications.
