NBR Rubber Products Use

Nitrile rubber is made by and by the emulsion polymerization of acrylonitrile, butadiene nitrile rubber is mainly produced by emulsion polymerization at low temperature, excellent oil resistance, high wear resistance, good heat resistance, strong adhesive relay. Its disadvantages are low temperature tolerance, poor ozone resistance, low electrical performance and slightly lower elasticity. Butyronitrile rubber is mainly used in the manufacture of oil-resistant rubber products. A synthetic rubber made from butadiene and acrylonitrile. It is a synthetic rubber that is resistant to oil (especially paraffin oil) and is resistant to aging. The acrylonitrile content (%) in the acrylonitrile rubber is 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30, 18 ~ 24, etc. The more acrylonitrile content, the better the oil resistance, but the cold tolerance decreases accordingly. It can be 120 ℃ 120 ℃ in air or in the oil medium and long term use. In addition, it also has good water resistance, air tightness and good bond performance. Is widely used in various oil resistant rubber products, a variety of oil resistant gaskets, gasket, casing, flexible packaging, soft hose, printing and dyeing, plastic roller, plastic cable materials, etc., in automotive industry, aviation, petroleum, photocopying etc become indispensable in the elastic material.

Basic performance

The nitrile rubber has excellent oil resistance, which is second only to polysulfide rubber and fluoro rubber, and has the abrasion resistance and air tightness. The disadvantage of the rubber is that it is not resistant to ozone and aromatic, halogenated hydrocarbon, ketone and ester solvents.

The main purpose

Nitrile rubber is used mainly for oil products, such as tubing, adhesive tape, rubber diaphragm and large oil capsule, etc., are often used to make all kinds of oil resistant moulded products, such as o-ring, oil seal, cup, diaphragm valve, corrugated pipe, etc., are used to make plastic board and wear-resistant parts.


(synthetic high molecular compound) is the main raw material of chlorobutadiene, which is obtained by means of polymerization or a small amount of other monomers. For example, anti-tensile strength, heat resistance, light resistance, good aging resistance and oil resistance are better than natural rubber, styrene butadiene rubber and shunt-butylene rubber. It has a strong flammability and excellent resistance to extensibility. It has high chemical stability and good water resistance. The disadvantages of chloroprene rubber are electrical insulating properties, poor cold resistance and unstable storage. Neoprene USES a wide range of applications, such as the preparation of belts and belts for transport, the wrapping of wires and cables, the manufacturing of oil-resistant rubber pipes, washers and chemical corrosion-resistant equipment lining.

Chloroprene rubber is made from 2-chlor-1, 3-butadiene monomers through emulsion polymerization, which can be modified by sulfur and 2, 3-dichloro-1, 3-butadiene (ACR).

Chloroprene rubber can be used in different technical fields, mainly in the field of rubber industry (61%). But it is also very important as the raw material of adhesives, and has different applications (6 %), such as impregnating products (such as gloves), molding foam material, asphalt modification, etc.

Applications in elastomers are very wide, such as moulded products, cables, belts, conveyors, profiles, etc.

Neoprene does not have a particularly outstanding performance, but its comprehensive performance in synthetic rubber is unique. It has:

1, excellent mechanical strength 2 high ozone resistance and weatherability good aging resistance low flammability 4 5 6 moderate oil resistance good chemical resistance and flame resistance 7 can stick repeatedly on many substrates

Chloroprene rubber can be vulcanized by using different catalytic systems to allow it to be vulcanized within a wider range of temperatures.
