Few rubber additives should not in the list

- Jun 19, 2019-

The "List" issued by the Ministry of Environmental Protection website covers 887 products that are involved in high-pollution or high-environmental environmental hazards and a variety of key equipment for surrounding environmental protection. The solicitation period is closed until December 6. The "List" participated in the current tension promoters and anti-aging agents in the rubber additives industry in China. Among them, 728-730 listed the accelerators MBT, CBS and DCBS as high-pollution and high-environmental hazard products, 732-734 The listed anti-aging agents 6PPD, TMQ and IPPD are listed as high ambient environmental hazard products.

Without rubber additives, there is no rubber industry. Professor, secretary-general of China Rubber Helping Agents Professional Committee, said that the total output value of China's rubber industry in 2016 was over one trillion yuan, occupying a very tight position. At the same time, rubber additives are the strong raw materials of the rubber industry, the growth of rubber additives. And the stable supply is the guarantee of the normal growth of China's rubber industry.

Since the beginning of this century, China's auxiliaries industry has been pursuing clean production processes, and has gradually eliminated the polluting products such as accelerator NOBS and anti-aging agent D. The key rubber additives are from the production process to waste disposal. The craftsmanship is moving toward non-toxic and harmless.

Professor added road, the output of accelerators and antioxidants accounted for 63% of the total output of rubber additives. Among the accelerators, the production of sulfenamide accelerators reached 164,000 tons, accounting for 49.5% of the total accelerator. Among the anti-aging agents, ketone amines and p-phenylenediamine anti-aging agents are the tense anti-aging system products of tire rubber compounds. The amine anti-aging agents account for about 90% of the total anti-aging agents. The anti-aging agents 6PPD, IPPD and TMQ products. Accounted for 83.2%. Moreover, there are no substitutes for the six rubber auxiliaries listed this time. If these products are restricted, they will be tightly affected by the market.
