Acccelerator ya kapiira kye ki?

At present, the development of world accelerators is gradually becoming more environmentally friendly, functional and centralized. From a technical point of view. In recent years, the international toxicity of certain promoters in the rubber processing process, which is prone to harmful nitrosamines, has been paid more and more attention. In view of this, many restrictive regulations have been introduced in the world, Germany as early as 1982. In order to control the content of nitrosamines, the United States, Japan, France, and the United Kingdom have also actively developed new vulcanization accelerators that do not produce nitrosamines, and have subsequently stopped using nitroxene promoters. Therefore, an environmentally friendly vulcanization promotion system has been formed, and some new environmentally friendly varieties have been developed to replace products that are at risk of causing tumors. In terms of marketing, we pay more attention to the application performance research of products, and develop functionalized cavity accelerator masterbatch and predispersion. Increasing the research and development of compounding has become one of the main means for foreign major accelerator manufacturers to occupy and expand the market.
