In recent years, the technology level of domestic special rubber production and processing has been greatly improved, and the special rubber synthesis technology developed by various enterprises has been continuously released.

Special rubber

It has been widely used in various industrial and civil fields due to its excellent oil resistance, heat resistance and aging resistance. It has become a new chemical material with much concern.

In April 2010, the Petrochemical Industries Co Lanzhou Petrochemical Industries Co high performance HTPB, high molecular weight butadiene carboxylic acid, new nitrile carboxylic acid liquid rubber products industrial amplification experiment news came.

After identification, the technical specifications and application performance of the product can meet the needs of aerospace and national defense construction.

Lianyungang jintada Rubber Co., Ltd. announced in June 2010 that the self developed gas solid method chlorinated sulfonated polyethylene rubber (CSM) process has been identified through the results. It is the first time in the world to realize large-scale production of CSM by non-traditional process.

It is understood that over the years, domestic and foreign enterprises generally use the traditional process to produce CSM, which requires a harmful substance to be used as solvent in the production process. The environment, especially the ozone layer, is seriously damaged. Harmful gas generated in the production process endangers the workers' body, and nearly 0.5% of the harmful residues in the products are difficult to remove.

The gas and solid process tail gas developed by jintatai can be completely absorbed, the product has no residual toxic solvents, and there is no need for product desolvent in the production process, which greatly reduces the construction cost and production cost of the plant.

At present, the products have been exported to the United States, South Korea, Germany and other countries.

In August 2010, Jixi Sanyuan special rubber and Plastic Co., Ltd. was developed in Heilongjiang province.

New thermal conductive material

Synthetic rubber, HTR, is a national patent for producing cool rubber gasket.

According to introducing, this kind of cool and cool rubber pad uses the new heat conduction material synthesis rubber HTR manufacture, has solved the ordinary grass, the bamboo mat material thermal conductivity is low, does not cool the technical difficulty.

The new type of thermal conductive material, synthetic rubber HTR, is synthesized by polymer. It has specific thermal conductivity and specific heat capacity. It is made of no pressure and no heating vulcanization process.

At the fourth international chemical new material (Chengdu) summit, which ended in late August, Li Yong Wu, President of the China Petroleum and Chemical Industry Federation, proposed that the dominant enterprises should be encouraged to carry out merger and reorganization and promote the integration, scale and scale of the upstream and downstream industrial chains, forming several new chemical material bases such as special rubber, engineering plastics and high-performance composite materials.

Insiders pointed out that in the next few years, China's industrial and civilian areas of special rubber and

Thermoplastic elastomer

The demand will continue to increase.

Modern rail pit and urban construction require that the relevant facilities have higher speed, safety, stability and durability, and require excellent anti-seismic, sound insulation and other properties. These provide a broader stage for the application of special rubber and its products, and believe that the special rubber of our country will certainly make a great contribution during the "12th Five-Year" period.
