Solenoid valve sealing materials,NBR nitrile rubber

There are currently three most commonly used sealing materials for solenoid valves.
NBR nitrile rubber
It is produced by emulsion polymerization of butadiene and acrylonitrile. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor electrical properties, and slightly lower elasticity.
In addition, it has good water resistance, air tightness and excellent bonding properties. It is widely used in the production of various oil-resistant rubber products, various oil-resistant gaskets, gaskets, sleeves, flexible packaging, soft hoses, printing and dyeing rubber rollers, cable rubber materials, etc. It has become indispensable in the automobile, aviation, petroleum, copying and other industries. elastic material.
Nitrile rubber has excellent oil resistance, its oil resistance is second only to polysulfide rubber and fluororubber, and it has excellent wear resistance and air tightness. The disadvantage of nitrile rubber is that it is not resistant to ozone and aromatic, halogenated hydrocarbons, ketones and ester solvents, and is not suitable for use as insulation materials.
The main purpose
Nitrile rubber is mainly used to make oil-resistant products, such as oil-resistant pipes, tapes, rubber diaphragms, and large oil bladders. It is often used to make various oil-resistant molded products, such as O-rings, oil seals, leather bowls, diaphragms, valves, and bellows. etc., also used to make rubber sheets and wear-resistant parts.
