Application 

Cummings

There are three most commonly used sealing materials for solenoid valves.


Nitrite rubber

It is produced by emulsion polymerization of butane and acrylamide. Nitrite 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 also has good water resistance, air tightness and excellent bonding properties. Widely used in the manufacture of various oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, casings, flexible packaging, flexible hoses, printing and dyeing rubber rollers, cable rubber materials, etc., becoming indispensable in industries such as automobiles, aviation, petroleum, and copying The elastic material.


Nitrite rubber has excellent oil resistance, its oil resistance is second only to poly sulfide rubber and fluorine rubber, and has abrasion resistance and air tightness. The disadvantage of nitrile rubber is that it is not resistant to ozone and aromatics, hydrogenated hydrocarbons, ketones and ester solvents, and is not suitable for insulating materials.


The main purpose

Nitrite rubber is mainly used to make oil-resistant products, such as oil-resistant pipes, tapes, rubber diaphragms and large oil sacs, etc. It is often used to make various oil-resistant molded products, such as O-rings, oil seals, cups, diaphragms, valves, bellows, etc. It is also used to make rubber sheets and wear-resistant parts.


EPDM rubber

EPDM rubber is a terpolymer of ethylene, polypropylene and non-conjugated diene. Commercial production began in 1963. The annual world consumption is 800,000 tons. The main feature of EPDM is its superior resistance to oxidation, ozone and corrosion. As EPDM belongs to the polyolefin family, it has excellent vulcanization properties. Among all rubbers, EPDM has the lowest specific gravity. It can absorb a large amount of filler and oil without affecting the characteristics. Therefore, low-cost rubber compounds can be produced.


Molecular structure and characteristics: EPDM is a polymer of ethylene, polypropylene and non-conjugated diene. Diene has a special structure, and only one of the two bonds can be polymerized, and the unsaturated double bond is mainly used as a cross-chain. The other unsaturated one will not become the main polymer chain, only the side chain. The main polymer chain of EPDM is fully saturated. This feature makes EPDM resistant to heat, light, oxygen, and especially ozone. EPDM is essentially non-polar, has resistance to polar solutions and chemicals, has low water absorption, and has good insulation properties.

Fluororubber

The fluorine-containing rubber in the molecule has various types depending on the fluorine content, that is, the monomer structure; the fluorine hexafluoride rubber has better high temperature resistance than silicone rubber, chemical resistance, and resistance to most oils and solvents (ketones, esters) Except for class), weather resistance, ozone resistance are good, but cold resistance is poor; generally widely used in automobile, motorcycle, B and other products, chemical plant seals, the use temperature range of -20 ℃ ~ 260 ℃, when used at low temperature requirements There is a low temperature resistant type that can be applied to -40℃, but the price is higher.
