SBR is a good economical grade of all purpose rubber. It has no unique chemical resistance properties. It can be readily substituted for natural rubber. It is a staple in the HVAC and construction industries, as it is versatile, tough and stands up.

Buna-N is good general purpose compound that has excellent elastomeric properties. It is resistant to petroleum based products and is rated up to 212°F.

Fabric-Reinforced Neoprene handles a good balance of oil, flame, and weather resistance. The reinforcement makes it ideal for stress applications such as gaskets and diaphragm packings.

Silicone handles a wide temperature range of -65 to +400°F. It has superior water resistance and makes an excellent electrical insulator.

EPDM has excellent resistance to weather and ozone. It is commonly used for outdoor applications.

This FDA compliant Buna-N material is typically used in food processing applications.

Viton is well known for its excellent heat resistance (up to 400°F), fuel resistance and chemical resistance.

Neoprene is an all purpose elastomer that can provide ozone and weather resistance as well as oil and chemical resistance. It is not the best elastomer for any of these things but if you need something middle of the road, this is it.

SBR is a good economical grade of all purpose rubber. It has no unique chemical resistance properties. It can be readily substituted for natural rubber. It is a staple in the HVAC and construction industries, as it is versatile, tough and stands up.

Natural gum rubber is for applications requiring a soft rubber seal. It can conform to irregular flanges with bolt heads. It is non-marking, has exellent tear strength and is abrasion resistant.
