SINOALU-99 resist corrosion and abrasion extremely well. They are also have low thermal conductivity, and a high resistance to heat, acid and alkali. They are widely used in many fields, including petroleum, chemical engineering, fertilizer production, natural gas and environmental protection. SINOALU-99 are the ideal filler of chemical industry furnace,reactor, packed tower in the chemical lines.
