Brief analysis of the application of silica in plastics

The white carbon black industry in developed countries such as Europe and the United States began industrial production in World War II. Since the mid-1970s, with the deepening of silica research in Western countries, its production and application fields have been greatly developed. Many industries of white carbon black are widely used. The following white carbon black manufacturers introduce to you. Plastic application:

China's white carbon industry began in 1958 and developed slowly. In 1984, white carbon black produced 2,600 tons. In 1990, silica production increased to 20,000 tons. In recent years, with the development of the rubber industry, China's silica production has grown rapidly by 71,000 tons in 2008, and its output ranks first in the world. It has become a net exporter of silica. At present, China's silica industry has formed a foreign-funded (joint venture) company, and domestic enterprises coexist in the market competition pattern, and market competition is sufficient.

The use of gas phase carbon black light transmission, small volume, can make plastics more compact, adding fumed silica to polystyrene plastic film, not only improve its transparency, strength, toughness, waterproof performance and anti-aging performance Adding ordinary plastic polyvinyl chloride and a small amount of gas precipitation method, the hardness of the steel door and window after the production of white carbon black manufacturers, the finished product and anti-aging performance are greatly improved. The main technical indicators (water absorption rate, insulation resistance, compression residual deformation, flexural strength, etc.) all meet or exceed the performance index of engineering plastic nylon 6, and realize the polypropylene railway. The replacement of nylon 6 for accessories has greatly reduced the cost of the product, and its economic and social benefits are very significant.
