<span styl

ORK Heat Resistant Nitrile Rubber O Ring Seal 70±5 Shore Hardness Free Sample
 
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°F to +120°F) 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.

 

Temperature Range
Standard Compound: -30° to +120°

Hardness (Shore A): 40 to 90.

Features: Comprised of the copolymer butadiene and acrylonitrile, in varying proportions. Compounds can be formulated for service temperature ranging from -30° to +120°. Use of Carboxylated Nitrile can have superior abrasion resistance, while still having improved oil resistance.

Limitations: Nitrile compounds are attached by small amounts of Ozone. Phthalate type plasticizers are commonly used in compounding Nitrile Rubber. These plasticizers can migrate out and cause problems with certain plastics. Also, new regulations on certain phthalates have limited their use.
