UHMW is ultra high molecular weight polyethylene that has exceptionally high abrasion and impact resistance properties. It will outwear all other materials, including metals, nylons, urethanes and fluoroplastics in some applications. In corrosion resistance, it has the same qualities of other polyethylene plastics. a very tough material, with the highest impact strength of any thermoplastic presently made. It is highly resistant to corrosive chemicals, with exception of oxidizing acids. It has extremely low moisture absorption, has a very low coefficient of friction, is self-lubricating, and is highly resistant to abrasion (15 times more resistant to abrasion than carbon steel). Its coefficient of friction is significantly lower than that of acetal. It is odorless, tasteless, and nontoxic.
