Product Description

Sealing material broadcast EDITOR There are three most commonly used sealing materials for solenoid valves. NBR nitrile rubber
Made of butadiene and acrylonitrile by emulsion polymerization, nitrile rubber is mainly produced by low temperature emulsion polymerization, 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 also has good water resistance, air tightness and excellent bonding properties. Widely used in the production of a variety of oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, bushings, flexible packaging, soft hose, printing and dyeing roller, cable rubber materials, etc., in the automotive, aviation, petroleum, copying and other industries to become an essential elastic material.Nitrile rubber has excellent oil resistance, its oil resistance is second only to polysulfide rubber and fluorine rubber, and has 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 insulating materials.Main useNitrile rubber is mainly used in the production of oil-resistant products, such as tubing, tape, rubber diaphragm and large oil capsule, etc., often used in the production of various oil-resistant molded products, such as O-rings, oil seals, leather bowls, diaphragms, valves, bellows, etc., and also used in the production of rubber plates and wear-resistant parts.

EPDM ethylene propylene diene rubber Ethylene propylene diene (EPDM) rubber is a terpolymer of ethylene, propylene and non-conjugated diolefin, which began commercial production in 1963. Worldwide consumption is 800,000 tons per year. The most important characteristic of EPDM is its superior oxidation resistance, ozone resistance and erosion resistance. Epdm rubber belongs to the polyolefin family, it has excellent vulcanization characteristics. Among all rubbers, EPDM has the lowest specific gravity. It can absorb a lot of fillers and oil without affecting the characteristics. This makes it possible to make rubber compounds at low cost.Molecular structure and properties: EPDM is a terpolymer of ethylene, propylene and unconjugated diolefin. Diolefin has a special structure, only one of the two bonds can copolymerize, and the unsaturated double bond is mainly used as the cross-chain. The other unsaturated one will not become the main chain of the polymerization, it will only become the side chain. The main polymer chain of EPDM is completely saturated. This property makes EPDM resistant to heat, light, oxygen, and especially ozone. Epdm is essentially non-polar, resistant to polar solutions and chemicals, has low water absorption, and has good insulation properties.
