High fluorine rubber has excellent methanol resistance and has good application prospects in the automotive field.

Fluorine rubber refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. Due to the introduction of fluorine atoms, the performance of fluorine rubber has been greatly improved. As the fluorine content increases, the methanol resistance of fluorine rubber is significantly improved, and the fuel transmittance is reduced. In recent years, as environmental protection regulations have become increasingly strict, bio-alcohol fuel has become more and more popular. It is widely used in the automotive field. Against this background, the market has also put forward higher requirements for the resistance of fluorine rubber, and the market demand for high-fluorine rubber has been released.

High fluorine atom content in high fluorine rubber is high, fluorine atoms have a great adsorption effect, and the C-F bond composed of fluorine atoms and carbon atoms has high performance, making high fluorine rubber have excellent heat resistance, chemical resistance, and chemical resistance. Vacuum resistance, oil resistance, aging resistance, solvent resistance, etc., but its low temperature resistance decreases. High-fluorine rubber has excellent performance, and its downstream applications involve automobiles, aerospace, seals, shock-absorbing parts, sporting goods, engineering rubber and other fields. Among them, automobiles are the main application scenario of high-fluorine rubber.

According to the “2021-2026 China High Fluorine Rubber Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, my country’s total automobile production and sales have ranked first in the world for 13 consecutive years. According to data released by the Ministry of Industry and Information Technology, in 2021, my country’s automobile production will be 26.082 million vehicles and sales will be 26.275 million vehicles, a year-on-year increase of 3.4% and 3.8% respectively. Sales of new energy vehicles Reaching 3.521 million vehicles. The scale of the automobile industry continues to expand, which is beneficial to the development of the high-fluorine rubber industry.

At this stage, many companies around the world have developed high-fluorine rubber and implemented commercial applications, including DuPont of the United States, Solvay of Belgium, 3M of the United States, Daikin of Japan, Akzo Nobel, Sanaifu Company, etc. . High-fluorine rubber is mainly used in the field of automobile fuel hoses. Against the background of increasingly stringent automobile exhaust emission restrictions, high-fluorine rubber is expected to gradually replace nitrile rubber and silicone rubber and become the mainstream product in the market.

my country is a major producer of fluororubber, but most of its production capacity is concentrated in the mid- to low-end fields, and high-performance special fluororubber still relies on imports. In terms of high fluorine rubber, the high fluorine content ternary fluororubber, high fluorine content peroxide vulcanized fluororubber, and high fluorine content fluorine rubber raw rubber developed by Chenguang Research Institute have been put into mass production. However, compared with foreign products, domestic high-fluorine rubber still has room for improvement in terms of methanol resistance and compression resistance.

Industry analysts said that high-fluorine rubber has high fluorine content and excellent methanol resistance. With the widespread use of bio-alcohol fuel in the automotive field , the demand for high-fluorine rubber in the automotive field has also been released, and the high-fluorine rubber industry has broad development space in the future. my country is a major producer of fluorine rubber. However, due to the weak research and development capabilities of enterprises, there is still a gap between my country’s high-fluorine rubber and foreign countries in terms of scale, performance, variety, etc., and there is a large room for improvement of domestically produced high-fluorine rubber.
