Nitrile Butadiene Rubber (NBR) Seat Butterfly Valve, Good compressibility

Nitrile Butadiene Rubber (NBR)

Nitrile Rubber is composed of acrylonitrile and butadiene. The content of acrylonitrile ranges from 18% to 50%. The higher content of acrylonitrile, the better resistance to hydrocarbon fuel oil of petrochemical oil, while worse performance in low temperature. Generally using temperature is - 25 ~ 100 degree. Nitrile rubber is one of the most commonly used rubbers for oil seal and o-ring.

Advantages:

Good oil resistance, water resistance, solvent resistance and high pressure oil resistance, it has good compressibility, wear resistance and elongation.

Disadvantages:

Not suitable for using in a polar solvent, such as ketones, ozone, nitro hydrocarbon, MEK and chloroform.

Application:

Used to produce fuel tank, lubrication oil tank and the rubber parts using in the fluid medium like hydraulic oil, gas, water, silicone oil, diester lubricating oil, etc., especially the sealing parts. As it were the most widely used and the lowest cost of rubber seals.

Material Quick Selection Table:

Material	Suitable Temp.	Characteristics
NBR	-35℃~100℃ Instant -40℃~125℃	Nitrile rubber has good self-expanding properties, abrasion resistance and hydrocarbon-resistant properties. It can be used as a general material for water, vacuum, acid, salt, alkali, grease, oil, butter, hydraulic oil, glycol, etc. Can not be used in places such as acetone, ketone, nitrate, and fluorinated hydrocarbons.
EPDM	-40℃~135℃ Instant -50℃~150℃	Ethylene-propylene rubber is a good general-purpose synthetic rubber that can be used in hot water systems, beverages, dairy products, ketones, alcohols, nitrates, and glycerin, but not in hydrocarbon-based oils, inorganics, or solvents.
CR	-35℃~100℃ Instant -40℃~125℃	Neoprene is used in media such as acids, oils, fats, butters and solvents and has good resistance to attack.
FKM	-20℃~180℃	Fluororubber is a good hydrocarbon-resistant base oil, fluorinated hydrocarbon rubber for oily gas and other petroleum products. It is suitable for water, oil, air, acid and other media, but it can not be used for steam, hot water or thicker than 82 °C. Alkali system.
SR	-70℃~200℃	Silicone rubber is resistant to high temperature, low temperature and stable chemical properties, and is widely used in industries such as strong acid, weak alkali and food.
Special materials: carboxylated nitrile rubber, hydrogenated nitrile rubber, corrosion-resistant ethylene-propylene rubber, steam-resistant fluoroelastomer, chlorosulfonated polyethylene
