Alumina Ceramics: 99 alumina ceramics vigorously develops the production of raw material styrene, and completely solves the problem of lack of polystyrene raw materials. The lack of raw materials restricts the development of polystyrene production, so solving the problem of raw materials is one of the keys to the development of polystyrene production. According to forecasts, the domestic production capacity of polystyrene will reach 2.2 million tons by 2005 and 3 million tons in 2010. The demand for styrene is very large, and the planned styrene production capacity still cannot meet the demand. The huge demand of polystyrene for styrene provides the two major oil and petrochemical group companies with a good opportunity to develop styrene production. The two major group companies are important domestic styrene producers. Trying to expand the production capac…
