Product Description

Oil Resistant Rubber Strip,Nitrile Rubber Strip  is a copolymer formed by polymerization of acrylonitrile and butadiene monomers. It is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance, and adhesion. The relay is strong. The disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity.

Nitrile rubber is mainly used to make oil-resistant rubber products. The acrylonitrile content (%) in nitrile rubber has five types: 42-46, 36-41, 31-35, 25-30, 18-24. The more acrylonitrile content, the better the oil resistance, but the cold resistance decreases accordingly. It can be used for a long time in the air at 120°C or in oil at 150°C. 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.

 

Performance of Nitrile Rubber Strip 

NBR has excellent oil resistance. Butadiene monomers can be copolymerized into three different chain structures: cis, trans and 1,2-alkylene groups. In a typical NBR structure, the trans form accounts for about 78%. Because NBR contains cyano groups in its molecular chain structure, its oil resistance (such as mineral oil, liquid fuel, animal and vegetable oil and solvent resistance) is better than natural rubber, neoprene rubber and styrene butadiene rubber. Compared with other rubbers, NBR has a wider range of use temperature. Its long-term use temperature is 120oC. At the same time, NBR has good low temperature resistance, and the lowest glass transition temperature can reach -55oC.

NBR has good chemical resistance and good processing performance. With the content of propionitrile in its structure, its relative density increases, vulcanization speed increases, and tensile strength performance increases, but its resilience performance decreases and cold resistance deteriorates. Since the cyano group in NBR is easily polarized by the electric field, the dielectric performance is reduced, and it is a semiconducting rubber. NBR can be divided into five categories: ultra-high, high, medium-high, medium and low acrylonitrile according to the level of ACN content. There are two production methods: continuous and batch polymerization. The continuous polymerization method is usually used for small variety and large-volume production with low consumption. The batch polymerization method is suitable for multi-variety and small batch production. The number of polymerization tickets is small and the construction consumption is high. So far, there is no trend of mutual substitution.

Although nitrile rubber has excellent physical and mechanical properties and processing properties, it is not as good as fluorine-like rubber and acrylic rubber in long-term use in sour gasoline and high temperature (150oC) environments. For this reason, German companies, Canadian companies and Japanese companies Developed hydrogenated nitrile rubber (HNBR) with excellent performance. In addition, it has also developed extremely super cold resistance and high purity nitrile rubber and shuttle-based nitrile rubber (XNBR).

 

The Main Purpose

Because of its excellent oil resistance and physical and mechanical properties, NBR is widely used in the manufacture of various oil-resistant rubber products, such as O-rings, gaskets, hoses, fuel tank lining rubber, printing rollers, oil tank linings, insulating floor boards, oil resistance Shoe soles, hard rubber parts, fabric coatings, pipe thread protection layers, pump impellers and wire wraps, adhesives, food packaging films, rubber gloves, etc. In 2014, there were more than 30 countries producing NBR in the world. The largest consumption area was the production of oil-resistant hose products and flame-retardant conveyor belts. The consumption of ft accounted for about 53% of the total consumption of NBR. Using nylon sandwich and chlorinated butyl rubber (am) as the inner and outer layer structure, it can produce a new type of hose that can prevent the seepage of Freon gas; using HNBR as the inner layer of rubber, nylon 66 as the reinforcing layer, and using CSM as the extension Manufactured cars. Power steering can withstand 4 million pulses at 12°C. In addition, nitrile rubber is also an ideal material for automobile Asahi continuously variable transmission tape, tire belt, automobile and aircraft fuel. Rubber is mainly used in the military, automobile , and aviation industries. It is mainly used in oil-resistant parts such as fuel tanks and slabs. It is also used in seals, transmission belts, hoses and plastic modified materials. The amount is increasing year by year. Almost all of them are stored. NBR is used more or less in rubber hose factories and miscellaneous goods factories. The second largest application field of nitrile rubber is sealing rubber products, which are widely used in aerospace devices, transformers, liquefied petroleum gas pipelines, gas fcl cover sinkers, and cars. Among them, automobile seals account for about 50% of the total consumption of seal inspection products. The annual nitrile inspection rubber used for wire and cable product s in China is about 1000t. The use of dynamic vulcanization technology and compatibilization technology can produce NBR /PP, NBR/PS, NBR/PVC> NBR/PA, NBR/ACR, NBR/CSM, NBR/EPDM, NBR/BR and other new alloy materials, which have good market prospects. NBR is also used to make oil-resistant adhesives Plates, printed rubber sticks, coal mine flame-retardant hydraulic hoses, oil tanks, fuel tanks, oil containers, oil-resistant rubber shoes, etc. 

It is mainly used in aviation, automobile, printing, textile and machinery manufacturing industries abroad. Due to the development of NBR modified varieties, the application prospect of nitrile rubber has been expanded. In summary, the main functions are: manufacturing flexible tanks, fuel oil pipes, oil limb cloths, oil seals, refueling pipes, oil-resistant rubber parts and various products in contact with them. Nitrile rubber has good compatibility with PVC and acid resin, so it is often blended with resin for material modification. In general , PVC is used to improve processing performance and impact resistance; aldehyde resin is used to obtain fertile materials to manufacture fluid materials after asphalt mixing.

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