Physical and chemical properties of sealing material NBR

Nitrile butadiene rubber is a copolymer of acrylonitrile ACN and butadiene. The overall performance of nitrile rubber on the whole relies upon on its ACN composition (generally 18% - 50%). The higher the ACN content, the better the oil resistance, but the lower the low temperature resistance

In a word, nitrile rubber has fantastic oil resistance and non-polar solvent resistance, as properly as precise mechanical homes and air tightness. It is appropriate for aliphatic hydrocarbon (propane, hexane, mineral oil and grease, gasoline oil), vegetable oil and animal oil, silicone oil, silicone grease, chemical furnace extinguishing agent, acid base salt answer diluted at low temperature, and water under one hundred ℃.

However, it has bad resistance to fragrant solvents, halohydrocarbon, ketone, ester solvents, and sturdy acids and sturdy bases. The climate resistance and ozone resistance of nitrile rubber are not strong either, however this hassle can be solved by way of mixing it with different materials.

Temperature range of Rubber NBR O Ring

General level: - 40~100 ℃

Low temperature resistance: - 55~100 ℃

High temperature resistance: - 30~125 ℃ (air) - 30~150 ℃ (oil)

Hardness range of sealing material NBR:

Shore A 40 °to 90 °

Color of NBR

Black, brown, green, white, red, yellow, blue, orange, gray, or colors designated by customers.

Application of sealing material NBR

Nitrile butadiene rubber is widely used in various oil resistant occasions. Fuel injector parts, electronic injection in automobiles, hydraulic and pneumatic industry, nuclear industry, etc.

Others: carboxyl nitrile rubber (XNBR)

Carboxylic nitrile rubber is comparable to nitrile rubber, however the primary section of the polymer is chemically modified by way of carboxylic acid group, ensuing in higher put on resistance and tear resistance than nitrile rubber. Therefore, XNBR is regularly used in environments the place put on resistance and oil resistance are demanding. But its low temperature flexibility, water resistance and compression deformation are poor, and the mixing security is now not high.

Temperature range: - 20 ℃~100 ℃ (125 ℃ in a short time).

Hardness range: Shore A50 ° to 90 °.
