Development of silicone rubber

Silicone rubber industry has made remarkable achievements. With the leap forward growth of consumption, silicone rubber industry has begun to change from high-performance special rubber to mass synthetic rubber, becoming one of the rubber varieties with the largest consumption. It is reported that in terms of the types of rubber consumed, natural rubber accounts for 41.8%, styrene butadiene rubber and CIS butadiene rubber account for 28.4%, while silicone rubber is usually only used in a few non tire fields such as building sealant and conductive keys, accounting for only 6.4% of the total rubber consumption. Therefore, as silicone rubber replaces other rubber in some non tire segments, its consumption will double and the market space will be further opened. In this regard, people in the industry also agree with the above views. It is estimated that by 2015, silicone rubber will account for 10% ~ 15% of the total domestic rubber consumption, that is, the consumption of silicone rubber is expected to reach 1 million ~ 1.5 million tons, while by 2020, the proportion of silicone rubber in the total rubber consumption is expected to reach 20% ~ 33%, that is, the consumption of silicone rubber is expected to reach 3 million ~ 5 million tons. In other words, the development potential and long-term development of silicone rubber industry are very attractive, and its rapid development will have a far-reaching impact on upstream and downstream industries. In fact, the linkage effect of upstream and downstream industries of silicone rubber industry has begun to appear gradually. Some experts pointed out that the biggest highlight of the development of silicone rubber industry is that it can greatly improve the domestic self-sufficiency rate of rubber. According to statistics, if the proportion of silicone rubber in China's rubber consumption increases from 6.5% to 33% by 2020, the overall domestic self-sufficiency rate of China's rubber can be increased from about 50% to more than 80%, so as to greatly alleviate the shortage of rubber supply and reduce the production cost of rubber processing industry. It can be seen that the development of silicone rubber industry is not only the single development of a single industry, but also involves the common development of multiple industries, which is of far-reaching significance for enhancing the profitability of rubber processing industry and improving the quality level of rubber products.
