It is understood that the bromobutyl rubber project was jointly developed by Hangzhou Longshan Chemical Co., Ltd., Zhejiang University, and Zhejiang Qicheng Technology Co., Ltd. Recently, the project partners specially held a press conference for the bromobutyl rubber project and announced that the technical indicators of their products have been tested by authoritative departments such as the National Rubber Research Institute and have reached international standards; by trial by users, they can completely replace imports.
According to project manager Peng Li, brominated butyl rubber is a star product in modern synthetic rubber and an important strategic material of the country. Butyl rubber has excellent airtight properties, heat resistance, abrasion resistance and other properties, is an ideal material for the production of automotive tires, while the performance of bromobutyl rubber is further improved. The annual demand for butyl rubber and brominated butyl rubber in China is about 250,000 tons, and it is growing at a rate of 15% year-on-year. However, because of the high production technology requirements, butyl rubber is currently only industrialized in a few countries such as the United States, Germany, Italy, and Russia. The only production facilities for bromobutyl rubber are Exxon of the United States and LANXESS of Germany. Uniquely, China's market and prices have long been under foreign monopoly control.
China began to develop butyl rubber and brominated butyl rubber technology in the 1960s, but it was restricted by various conditions and the industrialization process was very slow. At the end of the 1990s, Beijing Yanshan Petrochemical Technology Co., Ltd. had introduced a butyl rubber production plant by means of technology introduction and achieved a production capacity of 45,000 tons/year. It is the only large-scale butyl rubber plant in China. However, domestic production of bromobutyl rubber is still blank. Starting from last year, Longshan Chemical and its partners based on the results of the small-scale test of Zhejiang University, launched independent research and development of brominated butyl rubber production technology, achieved breakthroughs and broke the international monopoly.
China Tire Leading Enterprise Zhongce Rubber Co., Ltd. provided support for the testing and testing of pilot products. The company announced the test data and conclusions at the press conference and concluded that “this product can be normally used in the inner steel radial tire inner linerâ€. The company’s senior engineer, Lou Qichen, said that China is a big tire manufacturing country, but it has been subjected to high standards in the supply of high-grade raw materials for a long time, which is a great disadvantage for the development of the industry. The localization of bromobutyl rubber will improve the international competitiveness of China's tire industry.
In the next phase, the project team will further improve the pilot test results and begin the design work of the 10,000-ton project software package.
Bromobutyl rubber breaks international monopoly
On December 6, the reporter learned from Hangzhou Longshan Chemical Co., Ltd. that China's independently developed brominated butyl rubber product had been successfully tested, breaking the long-term international monopoly in this field and achieving a breakthrough of zero.
