O-rings made of NBR rubber have high swelling resistance to benzenes, oils and fats, work at high temperatures - this is the main material for the production of O-rings, they are used in fields with relevant requirements, such as hydraulics, engine building, mechanical engineering, oil industry, apparatus building.

RubberNBR(or nitrile acrylic rubber) - one of the most commonly used types of rubber in industry, has a high resistance to the aliphatic series of hydrocarbon oils and burning substances. There are various classifications of nitrile rubber depending on its manufacturer. The more NBR contains acrylic acid nitrile (AAN), the higher its oil resistance, but the elasticity of NBR at low temperature decreases.

PropertiesNBR

NBR has high elasticity and wear resistance, resistance to weathering and aromatic oil. Nitrile rubber can be used down to -30°C, but special grades of NBR can also be used at lower temperatures. The following is a list of NBR properties:

Nitrile rubber belongs to the group of unsaturated copolymers of acrylonitrile and butadiene.
The physical and chemical properties of nitrile rubber vary depending on the acrylonitrile polymer composition.
Various grades of NBR are available. The higher the content of acrylonitrile, the higher its oil resistance.
It has good resistance to combustible fuels and other chemicals.
Can withstand a wide range of temperatures.
Nitrile rubber is also resistant to aliphatic hydrocarbons (propane, butane, gasoline, mineral oils (lubricating oil, hydraulic oils groups H, H - L, H - LP)
It has less resistance to ozone, aromatic hydrocarbons (ARC), esters of keto acids, aldehydes.
NBR has high elasticity and wear resistance.
Nitrile rubber can be used down to -30°C, but special grades of NBR can also be used at lower temperatures

ApplicationNBR

NBR synthetic nitrile rubber is the most reliable agent in use in automatic and industrial installations.

In the automotive industry, NBR is used as a material for drainage mechanisms, hoses, pipes, hydraulic sleeves of mechanisms that work with combustible fuels and oil. Also, as a material for mechanical seals, bushings, insulating bushings for wires. With a temperature range from -40°C to +125°C, NBR can be used in automation. This form of synthetic rubber, due to its excellent wear resistance, is suitable for single-use laboratory cleaning and the production of examination gloves.

Use of Industrial NBR

Industrial nitrile rubber is used to make a number of different products:

Shaft cover
Hydraulic hoses - hoses for water supply
Conveyor belt (conveyor belt, conveyor belt, belt conveyor, conveyor belt)
Graphics, polygraphy, engraving
Hydraulic Collar, Packer for Oil Industry
Seals for all types of laying work (laying pipes, mechanisms, etc.)
Injection or transfer into molded articles/formed articles.
Pressing pipes or laying pipelines (tubing).
Calendered sheets and plates (car mats, etc., industrial belts)
Various sponges
Helmets
Seals /seals /mechanical seals
O-rings
Diaphragms for carburetors, fuel pumps: gasoline pumps, fuel pumps, fuel dispenser, oil pump, fuel pump, gasoline pump, gasoline pump, liquid fuel pump)
