SUNNYJOINT comments on What role does carbon black play in rubber tires?

- Dec 17, 2018-

Shenyang SUNNYJOINT as a supplier of Rubber Additives, Carbon black is mainly used in the rubber industry as the main product. The carbon black used in the tire industry accounts for more than 80% of the carbon black required by the entire rubber industry. Other rubber products other than tires of various motor vehicles (including motorcycles) are generally referred to as "rubber products". The carbon black consumed by rubber products accounts for about 20% of the carbon black for rubber.


    There are many kinds of rubber products, and the use conditions and performance requirements are different. According to the main functions, the products are tape, rubber hose, rubber sheet, rubber shock absorbing products, rubber sealing products, rubber rollers, conductive or antistatic rubber products, hard rubber and Rubber shoes and other major categories of products, and each type of rubber products are refined into several varieties according to the use and conditions of use. In order to meet the performance and use requirements of various products, rubber formulators choose a reasonable formula and various compounding agents from the use of rubber, vulcanization system, reinforcing filling system, softening system, anti-aging system and adding 3252 art system. And adding process conditions to meet the requirements of product performance.


    Carbon black is an important reinforcing filler in the reinforcing filling system. It has an important influence on the physical and mechanical properties and processing technology of the rubber compound, but it has a long-term influence on the properties of the heat-resistant, oil-resistant and corrosion-resistant medium of the rubber compound. Less than rubber, vulcanization system and protection system are large and direct. For this reason, the general rubber formulators do not pay much attention to the specific performance index of a certain carbon black than the carbon black technicians. They often only pay attention to the selection of a certain type of carbon black, and do not examine in detail the specific indicators of the use of carbon black, or through different The carbon black is used in combination, and the carbon black and the inorganic filler are used together to meet the requirements for use of the product. Therefore, it is difficult to quantify the impact of specific physical and chemical indicators of carbon black.
