IOTA introduces the development history of Silica


Since 1948, white carbon black has been produced and used in the rubber industry as a filler. By the 1980s, about 67% of precipitated Silica in the world was used in the rubber industry, of which 45% was used in footwear, 16% in tires, and 6% in other rubber products. Since the French Michelin Company announced to vigorously carry out the research on "green tires" in 1991, major tire companies in Europe, the United States and Japan have accelerated the pace of development. "Green tire" has become the mainstream of tire industry development in the 21st century. Silica can be used in high proportion or completely replace carbon black as a reinforcing agent to produce "green tire". In 1999, it was the standard practice for Europe to use white carbon black in the original car tire tread, and the amount of white carbon black in the original car tire tread has reached 100000 tons. Affected by the pressure of fuel tax, in order to reduce fuel consumption, automobile manufacturers actively develop "green tires" with low rolling resistance and low fuel consumption.
