Coloured High Temperature NBR O Ring

Coloured High Temperature NBR O Ring Water Resistant Strong Cohesive Force
Advantage: excellent resistant to gasoline and Fat hydrocarbon oil, second only to TR, ACM and FKM, better than other general rubber. Good heat resistance, good air tightness, abrasion resistance and water resistance, strong cohesive force.
Disadvantage: poor cold resistance and ozone resistance, low strength and bad flexibility, poor acid resistance, bad electrical insulation and polar solvents resistance.
Operating Temperature: about -30°C~+120°C.
Application: mainly used in manufacturing all kinds of oil-resistant products, such as rubber hoses and seals, etc.

 Standard O-Ring Material Applications


 Nitrile (Buna-N) is the most widely used elastomer due to its excellent resistance to petroleum products, operating temperature range (-30° to +120°) and one of the best performance-to-cost values. It's an ideal material for aerospace, automotive, propane and natural gas applications. Special Hydrogenated Nitrile (HNBR) compounds can improve resistance to direct ozone, sunlight, and weather exposure while increasing temperature range to +300°F


ASTM D1418 Designation: NBR


ASTM D2000/SAE J200 Type, Class: BF, BG, BK, CH


ORK Compound Designation: BN


Standard Color: Black


Description: Presently the seal industry's most widely used and economical elastomer, Nitrile combines excellent resistance to petroleum-based oils and fuels, silicone greases, hydraulic fluids, water and alcohols, with a good balance of such desirable working properties as low compression set, high tensile strength, and high abrasion resistance.


Key Use(s): Oil resistant applications of all types. Low temperature military uses. Off-road equipment. Automotive, marine, aircraft fuel systems. Can be compounded for FDA applications.
