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.

EPDM

−45 °C to +140 °C

The choice wherever water, steam, weather or ozone are involved. EPDM ages outdoors almost indefinitely and handles hot water and low-pressure steam that would destroy nitrile.

Neoprene (CR)

−35 °C to +120 °C

The balanced all-rounder. Moderate oil resistance combined with genuine weather resistance and inherent flame retardance — no other single compound covers that spread as cheaply.

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.
