Ultra-high-molecular weight polyethylene(UHMWPE) has extremely long chains which serve to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made.

UHMWPE has extremely low moisture absorption and a very low coefficient of friction; It is self-lubricating, and is highly resistant to abrasion. In some forms, it's 15 times more resistant to abrasion than carbon steel. Its coefficient of friction is significantly lower than that of nylon and acetal and is comparable to that of polytetrafluoroethylene(PTFE, Teflon), but UHMWPE has better abrasion resistance than PTFE.
