As an environmental friendly and excellent additive, silica is mainly used in the fields of rubber products (including high temperature vulcanized silicone rubber), textile, papermaking, pesticides and food additives. In recent years, due to the excellent reinforcement performance of silica, its dosage in rubber and plastic products has increased significantly, and the output of silica in China has increased rapidly. In 2010, there were about 60 precipitated silica production enterprises in China, with a total production capacity of 1.18 million T / A and an actual output of about 856000 T / A.



Thanks to the demand growth in tire manufacturing, silicone rubber industry, coating industry, new energy and other fields, it is expected that the average annual demand growth rate of precipitated silica (silica) in China will be about 10% in the future. In 2015, Asia will become the largest market for highly dispersed silica, and its demand growth rate will be much higher than the global average of 9%, reaching 15% or higher. China accounts for 40% of the Asian market and will become the largest single market in the world.
