Rubber additives are important auxiliary raw materials in the rubber industry, which play an important role in improving rubber processing, saving energy and improving product quality, etc., and are known as the "monosodium glutamate" of the rubber industry. With the rapid development of China's rubber chemicals industry in recent years, China has become a global production and supply of large countries. According to the rubber chemicals industry public information, after entering the 21st century, China's rubber chemicals production in 2001 was only 138,000 tons, as of 2022 has reached 1,374,900 tons, 741,000 tons in the first half of 2023, is expected to hit a new high this year!
Through the rubber chemicals 2020-2022 production structure chart, look at the rubber chemicals in recent years, the structure of the major categories of products change:
As can be seen from the figure, the growth of sulfurizing agents and peroxides category is obvious. This category mainly consists of elemental sulfur, selenium, tellurium and sulfur-containing compounds, organic peroxides, quinone compounds, amine compounds, sulfurized resins, metal oxides, other and other vulcanizing agents. Domestic widely used at present to sulfur type as the main vulcanizing agent. 2022 vulcanizing agent production 193,000 tons, an increase of 11.88% year-on-year. Its growth products are mainly insoluble sulfur, the domestic production amounted to 163,000 tons, and its export volume is at 29,000 tons.
