The development trend of silicone?

With the rapid increase in domestic market demand for silicone rubber, silicone rubber China has become the world's centers of consumption, and foreign major silicone rubber producing countries and regions, will also increase our market expansion efforts. Our neighboring countries, Japan, Russia, the silicone rubber production can have more than 1 million tons / year, while South Korea, Taiwan, China and Southeast Asia, the silicone rubber industry is also developing rapidly. Meanwhile, the main varieties of silicone rubber, a butadiene rubber (BR) has been able to meet domestic demand, styrene-butadiene rubber (SBR) plant construction is also accelerating the next few years may also be a surplus in recent years, domestic enterprises import anti-dumping proceedings have increased in the silicone rubber, these are harbingers of the future of domestic silicone rubber market competition will become increasingly fierce. Our silicone rubber industry has four major competitive advantage. Healthy development of the silicone rubber industry depends on its own technological progress continues to accelerate, strengthen high-performance product varieties. The current competitive advantage of China's synthetic rubber industry is that there are certain core technical support. China has established a relatively complete system of products includes seven basic types of plastic, which has a strong core of technical support SSBR (SSBR), thermoplastic styrene-butadiene rubber (SBS) and butadiene rubber (BR), and other products high domestic market share, and in accordance with the timely development of market capacity expansion capability, conducive to further expand market share. Ethylene-propylene rubber (EPR), acrylonitrile-butadiene rubber (NBR) and butyl rubber (IIR) construction equipment and other products imported technology, the products have successfully entered the market, and a certain development in plant capacity and product grades, etc., in order to further expand in the future market and the ability to lay the technical foundation. China has a huge market demand. Investment world rubber industry focus has shifted to developing countries, especially China, the country is becoming the world tire and rubber products manufacturing and processing base in the world and the silicone rubber key areas of market competition. Lack of domestic natural rubber resources. Our long-term demand of natural rubber imports in 2000 rose to 850,000 tons in 2007, more than 1.6 million tons, the foreign dependency increasingly improved. Increase the proportion of use of silicone rubber has become an important way to solve the problem of shortage of natural rubber, it can replace some or all of some natural rubber, silicone rubber will have a bigger market. Butadiene and other raw materials supply. The main raw materials to produce synthetic rubber is butadiene and styrene as well as a number of isobutene, acrylonitrile, ethylene, propylene, isoprene and chloroprene. Sustained rapid development of China's ethylene industry, will provide adequate resources butadiene synthetic rubber industry. With a number of new and expansion of domestic ethylene plant put into operation one after another, butadiene feedstock supply situation will be greatly improved, China's net imports of butadiene declined from 155,000 tons in 2004 to 86,000 tons in 2007 self-sufficiency rate increased from 82% in 2004 to 95% in 2007. The next few years, the amount of butadiene resources will no longer be a major factor restricting the development of silicone rubber. In addition, in 2010 China's styrene production capacity will reach about 600 million tons / year, while the demand is about 5.8 million tons over the same period, the contradiction between supply and demand will be basically solved. From a technical co-ordination arrangements or investment point of view, the ethylene plant by-products for the manufacture of silicone rubber and isobutylene-isoprene resources such as the status of long-term low-cost fuel use will gradually change. 2010, China's ethylene plant cogeneration EPA isoprene resources amounted to 300,000 tons, comprehensive utilization of resources and the development of EPA isoprene rubber by the industry more and more attention. Supply and demand of acrylonitrile, butadiene, chlorine and other raw materials will also be changed.
