The number of liquid polyisoprene companies is small and market competition has eased.

Liquid polyisoprene is a colorless and odorless viscous liquid. Its molecular chain structural units are similar to natural rubber (NR) and synthetic isoprene rubber (IR). It has good compatibility with NR and butadiene rubber. Therefore, in the rubber processing process, it can be used as a rubber additive for non-polar rubbers such as NR and butadiene rubber, and can be co-cross-linked with them to solve the problem of traditional plasticizers that are easy to volatilize at high temperatures and are easy to be extracted in solvents. and other issues, and is more environmentally friendly, which has attracted attention from all walks of life in recent years.

There are many polymerization methods for liquid polyisoprene, including anionic polymerization, free radical polymerization, coordination polymerization and thermal degradation. Among them, the anionic polymerization method has many advantages and is a polymerization method that has been studied in depth. With the advancement of research, liquid polyisoprene has been proven to have very good application effects in plasticizers, adhesives, sealants and other fields. In the field of plasticizers, liquid polyisoprene glue can not only give the rubber structure good processing properties, but also greatly improve the viscosity and adhesion of the product; in the field of adhesives, liquid polyisoprene is suitable for strength Bonds with low requirements but good sealing properties; in the field of sealants, liquid polyisoprene is often used in automobiles, construction, and daily necessities due to its heat and water resistance. Among them, adhesives are the traditional application field of liquid polyisoprene, and sealants are its more unique application fields. In the field of sealants, liquid polyisoprene has more development prospects.

China started research on liquid polyisoprene early. In the 1960s, the Petrochemical Research Institute of PetroChina Lanzhou Petrochemical Branch began to conduct research on the synthesis of liquid polyisoprene, but it did not form industrial production. After the 1970s, Japan made a major breakthrough in the production of liquid polyisoprene and began to occupy the global market. However, China’s liquid polyisoprene industry has been lagging behind. It was not until the 21st century that several companies appeared in China. Liquid polyisoprene manufacturer, and gradually catch up with the world’s leading level. According to the released “2023-2028 China Liquid Polyisoprene Industry Market In-depth Research and Development Prospects Forecast Report”, currently , China’s liquid polyisoprene production companies mainly include Shandong Yuhuang Chemical Co., Ltd., Henan Puyang Lin’s Chemical New Materials Co., Ltd., etc.

Industrial analysts said that liquid polyisoprene is still in the early stages of development. Due to the low maturity of production technology, production Due to factors such as high costs, a small number of manufacturing companies, and easing market competition, the current product price is at a relatively high level, which also affects its promotion and application. In the future, companies in the liquid polyisoprene industry need to strengthen production process development and reduce product production costs.
