Common Rubber Elastomers

Carboxylated Nitrile (CBNR)

Has excellent water, oil, and fuel resistance of conventional NBR. It has superior abrasion resistance and load bearing capabilities. It retains good physical properties over a useful temperature range of -40°F to 300°F.

Ethylene-Propylene (EPDM) (EPR)

Has outstanding resistance to oxygen, ozone, and sunlight. It is resistant to popular materials such as Phosphate Esters, many ketones, and alcohol. It has good electrical properties, low temperature flexibility, and excellent heat, water, and steam resistance. Its resistance to petroleum products is poor. Useful temperature range is 58°F to 300°F.

Fluoroelastomer (VITON) (FLUOREL)

Has good resistance to most chemicals and commercial fluids. It has an outside ability to retain strength at elevated temperatures an to withstand embrittlement during long-term hear aging. It has outstanding compression set with abilty to recover following deflection at up to 450°F. The temperature range is -22°F to 450°F, but will withstand temperatures up to 600°F  for short periods of time.

Hypalon (CSM)

Has outstanding oxygen, ozone, and weather resistance. It has excellent resistance to corrosive chemicals as well as oil and grease. It has excellent abrasion resistance and excellent tensile and elongation. Useful temperature range is -67°F to 320°F.

Natural Rubber (NR) (GUM)

Has excellent mechanical properties. It has excellent tensile, elongation, tear resistance, and resilience. It has good abrasion resistance and excellent low-temperature flexibility. Without additional additives, it has poor resistance to ozone, oxygen, sunlight, and heat. It has poor resistance to solvents and petroleum products. Useful temperature range is -67°F to 180°F.

Neoprene/Chloroprene (CR)

Has excellent physical propoerties. It is moderately resistant to petroleum products, sunglight, ozone, and heat. It is flame resistant and will not support combustion. Useful temperature range is -40°F to 275°F.

Nitrile/Buna N (HYCAR) (CHEMIGUM)

Has excellent physical properties, however its claim to fame is based on its resistance to water, petroleum products, and fuels. When compounded properly, it has good low temperature properties as well as good heat resistance. It does not have good ozone, oxygen, or sunlight resistance without the addition of special additives. Useful temperature range is -40°F to 275°F.


Has outstanding resistance to temperature extremes. It has excellent vibration dampening, and reasonable physical properties such as tensile and elongation. Tear and abrasions resistance are generally poor. Useful temperature range is -148°F to 600°F.

Styrene Butadiene (SBR) (BUNA-S) (GRS)

Has similar properties to Natural Rubber. Its resistance to solvents and petroleum products are about the same as Natural Rubber. Without special additives it is vulnerable to ozone, oxygen, and sunlight. Useful temperature range is -67°F to 180°F.
