…corrosive chemicals except some oxidizing acids. It has extremely low moisture absorption and a very low coefficient of friction; is self-lubricating (see boundary lubrication); and is highly resistant to abrasion. Its coefficient of friction is significantly lower than that of nylon and acetal and is comparable to that of…
