UHMWPE

UHMWPE stands for Ultra-high-molecular-weight polyethylene, also known as high-modulus polyethylene, (HMPE).

It is highly resistant to corrosive chemicals except oxidizing acids; has extremely low moisture absorption and a very low coefficient of friction; is self-lubricating (see boundary lubrication); and is highly resistant to abrasion, in some forms being 15 times more resistant to abrasion than carbon steel.
