產(chǎn)品說明

Rulon® W2 is a black PTFE-based material developed for use in fresh-water applications. It exhibits low friction and excellent wear characteristics (one of the lowest wear rates in fresh water) as well as good thermal dissipation, preventing shaft distress. Its properties are enhanced when wet.

Rulon® W2 is DWGV (European) certified for applications in contact with drinking water.

It is compatible with most metal substrates and soft mating surfaces. Rulon W2 is a good alternative to Rulon J when superior chemical resistance is needed. However, it should not be used on very soft mating surfaces or where electrical insulation is desired.
