Introduction of nitrile rubber
Nitrile rubber is a copolymer obtained by polymerizing butadiene and acrylonitrile monomers. The English name is Nitirle-Butadene Rubber, or NBR for short. It is one of the general raw materials for oil-resistant rubber products, and is widely used in the manufacture of oil-resistant gaskets, gaskets, rubber hoses, aircraft mailboxes, flexible packaging, printing and dyeing rubber rollers, cable materials and adhesives, etc. Many countries in the world are able to produce various grades of nitrile rubber. In addition to excellent oil resistance, nitrile rubber also has the characteristics of aging resistance, wear resistance, low air permeability and high cohesion, so its application fields are various.
Application of nitrile rubber
Thermal insulation foam material
Nitrile rubber foam is a relatively common thermal insulation and shockproof material. Nitrile rubber foam has excellent waterproof, moisture-proof, thermal insulation, heat insulation, cushioning and shockproof, sound absorption, sound insulation, sealing, flame retardant and other characteristics.
Sealing products
Nitrile rubber sealing ring is suitable for use in petroleum hydraulic oil, glycol hydraulic oil, diester lubricating oil, gasoline, water, silicone grease, silicone oil and other media. It is the rubber seal with the widest application and the lowest cost at present. . However, it is not suitable for polar solvents such as ketones, ozone, nitrohydrocarbons, methyl ethyl ketone and chloroform.
Hose, Tape Products
Mechanical hydraulic hose, hydraulic hose is composed of inner rubber layer, reinforced layer and outer rubber layer. The inner rubber layer is directly in contact with oil, so it is required that it should not be corroded by fluid under long-term working conditions and can prevent leakage. It can withstand a certain pressure under the action of the reinforcement layer. Therefore, nitrile rubber should be used.
Industrial Rubber Roller
The characteristics of nitrile rubber rollers are as follows: ①Excellent wear resistance; ②Oil resistance is 30%-50% higher than natural rubber; ③Heat resistance is better, but not resistant to ozone; ④For non-polar and weak polar oils and Excellent resistance to solvents, but poor resistance to aromatic and chlorinated hydrocarbon oils.
