Descriptions of Compounds

Common Names:
Nitrile, Buna N®, NBR

Description:

Compounds of these polymers are the backbone of the O-Ring line. Polymers vary from 18 percent to 50 percent acrylonitrile content. Resistance to petroleum products increases as acrylonitrile increases; conversely, low temperature flexibility decreases. Government specifications require low acrylonitrile.

Nitrile Compounds can exhibit excellent compression set, tear and abrasion resistance. Unless especially compounded, they do not have good resistance to ozone, sunlight, or weather. They should not be stored near motors or other ozone generating electrical equipment. They should be kept from direct sunlight.

Recommended Temperature Range:
Compounds from nitrile rubber can exhibit a temperature range of -65°F to +300°F, although no one formulation may exhibit the total range.

Common Names:
Fluorocarbon, FPM, FKM, Viton®

Description:

Compounds of these polymers exhibit excellent resistance to petroleum products, low compression set and high temperature resistance. The low temperature capability is somewhat restricted, however, in some case the flow temperature sealing capability may be increased by specific design parameters. These materials meet the stringent requirements of Military Specifications Mil-R83248 and Aerospace Specifications AMS 7278, AMS 7279, and AMS 7280. They are especially good for hard vacuum service and low gas permeability.

Recommended Temperature Range:

The normal temperature service range in fluorocarbon is -20°F to +400°F / + 450°F, although no one formulation may exhibit the total range.

Common Names:
Ethylene Propylene, EP, EPDM

Description:

This material was introduced in 1961 and found broad acceptance in applications requiring excellent resistance to Skydrol and other phosphate ester fluids at higher temperatures. In addition, compounds of this material exhibit excellent resistance to automotive brake fluids and steam.

Recommended Temperature Range:
The temperature service range for these compounds is -65°F to +300°F, although no one formulation may exhibit the total range.

Common Names:
Silicone, VMQ

Description:

Silicones are noted for their excellent heat resistance, and are utilized in applications which expose seals to high temperature dry heat. They are not recommended for dynamic applications due to their relatively poor tensile and tear strength. They exhibit the best low temperature flexibility of all elastomers and can be used in static applications to -150°F. Silicones should be considered to be non-petroleum resistant, but can be used in specific high aniline point petroleum oils.

Recommended Temperature Range:
The temperature service range for silicone compounds is -80°F to 450°F (All silicone formulations do not exhibit the capability of this entire range).

Common Names:
Hydrogenated Nitrile, HNBR

Description:

HNBR was created to resist air and meet higher temperatures than nitrile rubber. In HNBR, the nitrile is hydrogenating which helps the material withstand higher temperatures and resist oxidation. HNBR is used in place of Nitrile, Ethylene Propylene, and Fluorocarbon elastomers in applications involving high temperatures and petroleum-based oils. HNBR is also suitable for dynamic applications.

Recommended Temperature Range:
The temperature service range for these compounds is -40°F to +300°F, although no one formulation may exhibit the total range.

Common Names:
Neoprene, Chloroprene, CR

Description:

​This was the earliest of the volume American synthetic rubbers. Compounds from neoprene exhibit fair oil resistance, good ozone and weather resistance. Due to the excellent resistance to refrigerants such as Freon, neoprene compounds are used in refrigeration systems. 

Recommended Temperature Range:
The sealing temperature service range for these compounds is -65°F to +250/300°F, although no one formulation may exhibit the total range.
