Low Coefficient of Friction
UHMWPE has a very low coefficient of friction and is self-lubricating. Its coefficient of friction is significantly lower than that of nylon and polyacetal, and is comparable to that of PTFE (Teflon), but UHMWPE has better abrasion resistance than PTFE (Teflon).
Coefficient of Friction
UHMWPE pipes have smooth interior surfaces which assure low friction loss and high flow rate. Because UHMWPE pipe do not rust, pit, scale, or corrode, the high flow rate continues for the life of the piping system.
