What is the role of carbon black in rubber?

Carbon black is mainly used in rubber in the rubber industry as the main product. The carbon black used in the tire industry constitutes more than 80% of the carbon black needed by the entire rubber industry. In general, rubber products other than tires for various vehicles (including motorcycles) are collectively referred to as “rubber products”; called. Black carbon consumed by rubber products accounts for about 20% of the black carbon used in rubber each year. There is a wide variety of rubber products with different usage conditions and performance requirements. According to the main functions of use, the products include tapes, hoses, rubber sheets, rubber absorbent products, rubber sealing products, rubber rollers, conductive or antistatic rubber products, hard rubber, and several categories of products such as rubber shoes. There is. , and each category of rubber products are refined into several types according to the purpose and conditions of use In order to meet the performance and use requirements of different products, rubber formulas choose reasonable formulas and various compounds from the use of rubber, vulcanization system, reinforcing filler system, softening system, anti-aging system and adding art system 3252 . and processing conditions to meet product performance requirements. Carbon black is an important reinforcing filler in the reinforcing filler system. This material has an important influence on the physical and mechanical properties and processing technology of the rubber compound, but it has a wide influence on the heat resistance, oil resistance and corrosion resistance of the rubber compound. It is not as large and direct as the tire, the volcano system and the protection system. For this reason, general rubber manufacturers do not pay as much attention to the specific performance indicators of a particular carbon black as carbon black technicians. They often only pay attention to the selection of a specific type of carbon black and do not examine or examine the specific indicators of the use of carbon black in detail. Different types of carbon black are used together, and carbon black and mineral fillers are used together. will be To meet product requirements. Therefore, it is difficult to determine the amount of specific physical and chemical indicators of carbon black.
