The cast polyurethane (CPU) industry has huge development potential. Yinuowei New Materials is a leading enterprise in my country

Casting polyurethane, the full name of cast polyurethane prepolymer, also known as cast polyurethane elastomer, refers to a new type of polymer synthetic material between rubber and plastic. It is liquid at room temperature and becomes solid after processing. Casting polyurethane has the advantages of strong wear resistance, good oil resistance, good aging resistance, wide applicability, strong impact resistance, and high elastic bearing capacity. It can be used in light industry, construction, textiles, machinery, electricity, automobiles, and petroleum , mining, natural gas and other fields.

According to different process principles, polyurethane elastomers can be divided into cast polyurethane elastomers (CPU), thermoplastic polyurethane elastomers (TPU), mixed polyurethane elastomers (MPU), etc. Compared with TPU and MPU, cast polyurethane has the advantages of wider product hardness range and more raw material selectivity. It has more advantages in the production of large and medium-sized products. It is one of the products with the widest application fields in the polyurethane elastomer market. , the market has broad room for development.

According to the “China Castable Polyurethane (CPU) Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center span> shows that currently cast polyurethane is mainly produced by a two-step method, which uses oligomer polyols, polyisocyanates, and chain extenders (cross-linking agents) as raw materials to react with polyols and polyisocyanates at a specific temperature. A process in which low molecular weight prepolymers are reacted with chain extenders and cross-linking agents to form cast polyurethane.

Among them, polyisocyanate is the key raw material required for the production of cast polyurethane. The main types include toluene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), polyphenylpolymethylpolyisocyanate (PAPI), etc. In 2022, domestic MDI production has exceeded 1.3 million tons, and TDI production has exceeded 1.5 million tons. The sufficient supply of raw materials has laid a good foundation for the development of the domestic cast polyurethane industry.

At present, my country has become the main producer of cast polyurethane in the world. There are many leading CPU companies in the country such as Shandong Yinuowei New Materials, Wanhua Chemical Group, Shengzhou Wanhe Polyurethane, and Suzhou Austin New Material Technology. In the future, as local companies gradually release their production capacity, the domestic cast polyurethane industry is expected to maintain a rapid development trend.

Industry analysts said that one of the leading enterprises in the domestic castable polyurethane industry, Yinuowei New Materials, the company’s castable polyurethane products are the most popular in the country. The single champion in the manufacturing industry, its technology has reached the international leading level, and its high-end product technology is leading. In the past two years, Yinuowei New Materials has accounted for more than 30% of the domestic castable polyurethane market, and the company has strong competitiveness. In the future, as the product performance of leading companies gradually improves and production technology continues to be upgraded, my country will gain more shares in the global high-end cast polyurethane market, and the industry has huge development potential.
