Due to its excellent oil resistance, heat resistance and physical and mechanical properties,
nitrile rubber has become the standard elastomer for oil-resistant rubber products, and is widely used in automotive, aerospace,
oil exploration, petrochemical, textile, wire and cable, printing and food packaging and other fields. At present, the domestic production is insufficient,
and the annual import volume is about 40,000 tons. In 2001, the global total annual production capacity of nitrile rubber was about 650,000 tons,
distributed in 17 countries and regions. Among them, the annual production capacity of China’s surrounding areas is about 270,000 tons,
accounting for 40% of the world’s total annual production capacity. Except for India, China is the main source of imports.
The largest use of nitrile rubber is the production of oil-resistant hoses and flame-retardant conveyor belts,
and its consumption accounts for about 50% of the total consumption; followed by sealing products,
about half of which are automotive sealing products; in wire and cable, adhesives, printing and luggage Products and other aspects also have applications.
In addition, the blending and modification of nitrile rubber and other materials has become a research hotspot. Using dynamic vulcanization technology and other technologies,
it is possible to prepare nitrile rubber/polyvinyl chloride, nitrile rubber/polypropylene, nitrile rubber/ethylene propylene rubber, nitrile rubber/polystyrene,
nitrile rubber/chlorosulfonated polyethylene, Nitrile rubber/polyamide, nitrile rubber/butyl rubber and other blended products,
of which nitrile rubber/polyvinyl chloride blend is the most widely used, mainly used in the wire and cable industry.
With the rapid development of the communication industry, it has strong competitiveness in the field of ethylene propylene rubber/polypropylene in the field of submarine cables.
At present, there are nearly 10,000 wire and cable enterprises in China, and the annual consumption of nitrile rubber/polyvinyl chloride is very large.
In addition, the blended adhesive can also be used in the outer layer adhesive of oil pipes and fuel pipes,
automotive waterproof seals and molded parts, foam insulation layers, rubber rings, protective coatings, etc.
