Through the introduction of foreign technology, China has built a 30kt / a butyl rubber production unit, and through continuous efforts in recent years, it has achieved safe and stable production, continuously increased output, and gradually increased its share in the domestic market. To a certain extent, it meets the actual domestic production needs. However, compared with foreign developed countries, there are still certain gaps, mainly in the following areas:
小 Small production capacity, low output and low self-sufficiency rate. The production capacity of China's butyl rubber is only 30kt / a, which is far lower than the production level of its economic scale of 50kt / a, and is even lower than the production scale of Exxon and Bayer companies above 70kt / a, resulting in relatively high production costs and self-sufficiency in products. The rate is only about 30%, and it lacks competitiveness in the international market. ⑵ The development of technology is not enough, and the variety and brand are still single. The three common butyl rubber product brands introduced in China have not been fully produced, and other modified butyl rubber products such as halogenated butyl rubber have not yet been produced, which has caused some high-level products to be imported in large numbers, and the general product has been sold passively. To a certain extent, it has affected the healthy development of China's butyl rubber; ⑶ the product quality is not stable enough. There are still some problems with butyl rubber products produced in China in terms of blocking, yellowing, product batches, volatiles, and Mooney value fluctuations, which need to be improved; ⑷ The scope of application of products is relatively small. About 84% of China's butyl rubber products are used in the automotive industry, and other applications are still relatively small; ⑸The technical service level can not meet the needs of users well. In order to make China's butyl rubber industry develop rapidly and healthily,
Butyl rubber manufacturers
⑴Improve product quality, save energy and material consumption, and improve the competitiveness of products in the market. Product quality is a key factor in product competition. Aiming at the problems existing in China's butyl rubber products, we should intensify technological innovation, continuously improve product quality, and take user requirements as the standard for product production; increase energy conservation and consumption reduction, reduce production costs, and make products more competitive in the domestic market competitive.
⑵On the premise of ensuring the normal and stable operation of the existing butyl rubber production equipment, accelerate the research and development and production of new varieties and new brands, increase the number of domestic butyl rubber grades, and constantly improve the product variety structure to better meet the market demand. In addition, in addition to increasing the demand for butyl rubber for tire inner tubes, we should also actively develop the non-inner tube rubber market for butyl rubber.
(3) Expand the production scale to meet the urgent needs of the domestic market and increase the domestic market share. The output of China's butyl rubber can only meet about one-third of the domestic demand. As the demand increases in the future, the satisfaction rate may be lower. Therefore, it is recommended that qualified enterprises can consider building 1 or 2 sets of 50kt / a. The above-scale production equipment can meet the needs of domestic actual production.
建成 Complete the production of halogenated butyl rubber as soon as possible. Halogenated butyl rubber occupies an important position in butyl rubber. With the development of application technologies such as radial tires, tubeless tires, and medical stoppers in China, the domestic demand for halogenated butyl rubber will increase. Therefore, China should start the preparation or introduction of halogenated butyl rubber production technology as soon as possible, and put it into production as soon as possible, so as to meet the needs of rubber for tubeless tires and other products in the domestic rubber industry.
⑸Strengthen applied technology research and improve service awareness and level. Strengthen ties and cooperation with relevant domestic applied research units or tire and other manufacturing enterprises, and research and develop special formulas and processing technologies for inner tubes, water tires and capsules suitable for domestic butyl rubber. At the same time, an expert marketing team is established to lay the foundation for the virtuous cycle of "market-development-production-market" of butyl rubber.
⑹ Actively expand exports and participate in competition in the international market. On the premise of meeting domestic demand, we should actively expand exports to the international market, especially to South Korea and other Southeast Asian countries in order to lay the foundation for future participation of butyl rubber in international competition.
