Differences Between HDPE and UHMW

HDPE (high density polyethylene) is a durable, versatile, low-cost, abrasion- and chemical-resistant plastic material. HDPE is easy to fabricate and weld using thermoplastic welding equipment. It is an excellent choice for fabricated water tanks and chemical tanks.

UHMW (ultra high molecular weight polyethylene) is an extremely tough, abrasion-resistant, low-cost plastic, used for a wide range of wear applications. UHMW is a popular plastic for countless industrial applications that require durability, low friction, and chemical resistance. Applications include UHMW wear strips, chain guides, and marine dock fender pads.
