Application: Widely used in petroleum,chemical industry,chemical fertilizer,natural gas,environmental protection and other fields,as the catalyst in the reactor cover support materials and tower filler,The main effect  is to increase the distribution of gas or liquid, to support and protect low strength active catalysts. Properties: With high temperature and high pressure resistance,low water absorption,chemical stability,acid and alkali resistance,resistance to organic solvent corrosion, the balls can with stand the temperature changes in the production process.High purity, high strength, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, thermal shock stability, chemical stability characteristics.
