Material notes

Nitrile (NBR)

−30 °C to +110 °C

The workhorse oil-resistant elastomer. Excellent resistance to petroleum oils, hydraulic fluids, greases and diesel, with good abrasion and compression-set behaviour at a modest cost.

PTFE / Teflon

−200 °C to +260 °C

Not an elastomer but a fluoropolymer, used as a bonded facing over a rubber backing. It gives a chemically inert working face while the rubber underneath supplies the flex.
