Liquid nitrile rubber market is widely used and the industry concentration is high

Liquid nitrile rubber (LNBR) has some properties of solid nitrile rubber. It is a new plasticizer and can act as a rubber softener. Because it has a similar molecular chain structure to solid nitrile rubber, it It can also participate in cross-linking during plasticization, so it is often used as a toughening modifier for epoxy resin, phenolic resin, polyvinyl chloride, solid rubber, etc. Liquid nitrile rubber makes up for the shortcomings of nitrile rubber in terms of application range.

In recent years, with the development of the national defense industry, aerospace, automobile industry, etc., people have put forward increasingly higher requirements for modified plastics, resins, rubber and other products in terms of quality and quantity. In recent years, global nitrile rubber manufacturers have gradually launched hydrogenated nitrile rubber (HNBR), liquid nitrile rubber (LNBR) and other specialized, differentiated and high-performance special nitrile rubber products to meet the needs of downstream automobile, The petrochemical industry has stricter requirements for rubber components. Domestic and foreign scientists have also conducted research on the properties, applications, and synthesis technology of liquid nitrile rubber. Overall, global research results on liquid nitrile rubber are gradually increasing, and the product specifications and models of the world’s leading companies are also constantly enriched.

According to the “China Liquid Nitrile Rubber Product Market Analysis Feasibility Research Report 2023-2027” released by the Industrial Research Center, currently , the liquid nitrile rubber sold on the market is mostly used in non-rubber industries, such as PVC modifier, adhesive (epoxy resin toughener), coating, etc. In addition, liquid nitrile rubber can also be used in the production of elastomers, hydrogenation to produce liquid hydrogenated nitrile rubber, and as a special heat-resistant and oil-resistant plasticizer. The terminals are involved in automobiles, modified plastics, building materials and other fields. Affected by technology and market, the number of liquid nitrile rubber manufacturers in my country is currently small, with only a few companies such as Anqing Hualan, Shanghai Shuorong Tianxia, ​​Hengshui Jiansheng Rubber and Plastic.

Industrial researchers believe that although my country is an important producer and demand country for liquid nitrile rubber in the world, the liquid nitrile rubber market has not yet Completely open, the industry has certain technical barriers. Except for Lanzhou Petrochemical, which has a high level of technology research and development, the technical level and product quality of other companies are not high. Overall, the domestic liquid nitrile rubber market is highly concentrated.
