Nitrile butadiene rubber

It is also called NBR.

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 and good heat resistance. 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. 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 fluorine rubber, 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.

Main uses

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

Introduction to EPDM rubber

EPDM rubber is a terpolymer of ethylene, propylene and non-conjugated dienes. It was commercialized in 1963 chemical production. Annual world consumption is 800,000 tons. The most important characteristic of EPDM is its superior resistance to oxidation, ozone and corrosion. Since EPDM rubber belongs to the polyolefin family, it has excellent vulcanization properties. Among all rubbers, EPDM has the lowest specific gravity. It can absorb large amounts of fillers and oils with little effect on properties. Thus a cost-effective rubber compound can be produced.

Viton (fluorocarbon rubber) is a synthetic rubber containing fluorine atoms. Fluorocarbon rubber has the characteristics of high temperature resistance, oil resistance and resistance to various chemicals. It is an important material for modern aviation, missiles, rockets, aerospace navigation, etc. An indispensable material for cutting-edge science and technology. In recent years, as the automotive industry's requirements for reliability and safety continue to increase, the use of fluorocarbon rubber in automobiles has also grown rapidly.
