China's development of synthetic rubber

At present, China's synthetic rubber used in self-sufficiency rate of only about half of each year a large number of imports. According to industry analysis, between 2000 and 2010 our country will be the main radial tire development and should therefore be focused on the development of isoamyl rubber, butyl rubber, ethylene-propylene rubber, halogenated butyl rubber, latex-Ling, and other varieties. The future of China's synthetic rubber industry should develop in the direction of the following:

1. Butadiene rubber

China's butadiene rubber is one of the most important kinds of plastic, but still the Department of Ni butadiene rubber-based, single brand. In recent years, Ni in the Department of butadiene rubber tires, rubber shoes and belt and other major applications were under the proportional use of force, so its future should be the development trend is to improve the technological level of production; further optimize the process and catalyst system; to develop new and polymerizer New blender; direct the development of drying; solvent instead of a single mixed solvents; and the realization of the entire process of brand switching, the TDC control, so as to minimize consumption, improve product quality inherent purpose of making international brand-name technology. At the same time should also be development on the one hand, oil-filled, modified and other brands, and open up new areas of the market; on the other hand, the use of high-level production technology, product quality, competitive, as well as the characteristics of surplus production capacity to increase exports.

Ni Department of butadiene rubber polybutadiene rubber other than the development of energy-saving high-performance tires to adapt to the impact modifier, as well as plastics applications such as the needs of the area, focusing on the development of low cis-polybutadiene rubber, high vinyl polybutadiene Rare Earth butadiene rubber and plastic, and other brands, as soon as possible so that the spring of industrialization series of brand products.

2, SBR

SBR is the development of our country in the direction of synthetic rubber, characterized SSBR, the need for the introduction of technology digestion, absorption and innovation, combined with our plans to improve the grades of polymer formulation, technology and the servants, so that The entire process to achieve control of TDC in order to reduce consumption and improve quality. At the same time, have to pay close attention to the development of new brands. Styrene-butadiene rubber production technology as the representative of the level of China's synthetic rubber industry as a whole.

Styrene-butadiene rubber in the next period of time is still needed gap. According to the national conditions of China in the next ten years, for the tire-styrene-butadiene rubber latex is still dominated, but solution-polymerized styrene-butadiene demand will continue to rise.

SBR-milk should focus on the development of the oil-filled brand, developed countries accounted for milk production in oil-filled brand-styrene-butadiene rubber production ratio of 60% to 70%, as a result of less than 20% of the domestic. At the same time also the development of styrene-butadiene rubber mixing carbon black mother, high styrene, as well as the electronics industry and other applications such as the need for the function of SBR.

SSBR capacity of the domestic market is currently small, annual consumption of about 20,000 to 30,000 tons, accounting for the entire SBR consumption ratio is roughly 10 percent, much lower than developed countries, 30% to 40%. As China's auto and tire industries to high-speed, security, energy conservation as the main content of the high-performance tires will be the rapid development of SSBR domestic demand will gradually rise, the market in 2005 is expected to reach capacity of 5 tons must . According to market forecasts, should pay close attention to tires and shoes with SSBR research and development of new products, including vinyl content, and oil-filled block random SSBR, and other brands, and further meet the "green tire" and "ultra-high Tire mileage, "New trends in the development of the tire, SIBR integrated research and development of new varieties, such as rubber.

3, butyl rubber

December 28, 1999, China's first butyl rubber production plant in Beijing Yanshan Petrochemical Company of synthetic rubber plant was completed and put into operation since the end of the butyl rubber production in China can not and must rely on imports of history.

Butyl rubber market in China is more extensive. In 1999, China's rubber consumption of 1,900,000 tons, of which the amount of synthetic rubber by nearly 50%, but the actual consumption of butyl rubber, only about 30,000 tons, the proportion was only 1.58 percent. If the developed countries in accordance with the butyl rubber in the proportion of synthetic rubber in terms of demand for butyl rubber should reach 90,000 tons, we can see China's potential market for butyl rubber is great. Globally, the butyl rubber focused on the development of high-performance halogenated butyl rubber, but China is no halogenated butyl rubber production capacity, so in the future development of butyl rubber at the same time we should vigorously develop halogenated butyl rubber .

4, NBR

As the special rubber, nitrile rubber with scattered users, industry wide application, the use of miscellaneous brands, technical requirements, simple to use less and so on. NBR targets of the world's great brand series, pluralism, segmentation, and the NBR our species of orchid in the introduction of 15,000 tons / acrylonitrile-butadiene rubber plant with an annual output of production, has reached 17 or so, but Production of less than ten grades, the gap there are still many brands, such as low-door nitrile low and high Mooney in nitrile, far from meeting the needs of the domestic market.

NBR in the future market development, should be expanded around the brand series of products to the serialization of products, diversify and broaden the field of application areas such as.

To sum up, by 2010 China's need for synthetic rubber will be increased to 1,800,000 to 2,200,000 tons.
