As a rubber reinforcing agent, carbon black has a wide range of applications. All black rubber products use carbon black. 
In 1912, it was discovered that carbon black had a reinforcing effect on rubber. Since then, carbon black has gradually become an indispensable raw material for the rubber industry. At present, the raw material consumption of the rubber industry in the world ranks first in raw rubber, and the second is carbon black; in other words, carbon black has become the most consumed rubber compounding agent. The consumption of carbon black generally accounts for 40%-50% of the consumption of rubber. That is to say, in the rubber formulation, usually 1  part of carbon black is used with every 2  part of rubber. 
 
      Silica is divided into precipitation method silica and gas phase method silica It is widely used in rubber products such as tires, tapes, hoses, rubber shoes, wires and cables. Silica and silane coupling agents are used in tire tread rubber. , It can improve the wear resistance and wet skid resistance of the tire while reducing the rolling resistance of the tire. The tensile strength, tear strength, abrasion resistance, etc. of the rubber compound using silica are improved, and it is used in transparent and colored rubber products. China has its advantages. With the enhancement of people's environmental awareness, the development of the tire industry and the continuous improvement of the quality of silica, its application range will be further expanded.   
       Silica began to be produced in 1948 and used as a filler in the rubber industry. By the 1980s, about 67% of the world’s precipitation method silica was used in the rubber industry, of which 45% were used in shoes and 16% were used in tires. , 6% is used for other rubber products. Since the French company Michelin announced in 1991 to vigorously carry out research on "green tires", major tire companies in Europe, the United States, and Japan have accelerated the pace of development. "Green tires" have become the mainstream of the tire industry in the 21st century. Silica can be used in a high proportion or replace carbon black as a reinforcing agent to produce "green tires." In 1999, it was standard practice in Europe to use white carbon in the original tires of cars. The amount of white carbon in the original tires of cars has reached 100,000 tons. Affected by the pressure of fuel tax, in order to reduce fuel consumption, automakers are actively developing "green tires" with low rolling resistance and low fuel consumption.  
      There are too many non-black rubber products such as rubber shoes, balls, toys, etc.
