Product Description
Ultra-high-molecular-weight polyethylene (UHMWPE, UHM) board is a very tough material, with the highest impact strength of any thermoplastic presently made.
UHMWPE board is odorless. tasteless, and nontoxic. It embodies all the characteristics of high-density polyethylene (HDPE) with the added traits of being resistant to concentrated acids and alkalis, as well as numerous organic solvents.
UHMWPE board is highly resistant to corrosive chemicals; has extremely low moisture absorption and a very low coefficient of friction; is self-lubricating and is highly resistant to abrasion, in some forms being 15 times more resistant to abrasion than carbon steel. Its coefficient of friction is significantly lower than that of nylon and is comparable to that of (PTFE, Teflon), but UHMWPE has better abrasion resistance than PTFE.
