Ceramic Foam Filters

Ceramic foam filter: They have low density (0.25 - 0.26), high porous (80 - 90%), good high-temperature resistance and chemical corrosion resistance and surface area. They can be widely applied in liquid filtering of melting metal in metallurgy, catalyst carriers, thermal exchanging material, automobile tail gas purifier and other adding materials in reacting tower.Specifications: 1) Materials: aluminum, silicon carbon, zirconia 2) Bore diameter (ppi): 10 - 60 3) Porosity (%): 80 - 90 4) Refractoriness (°C): 1,250 5) Compress strength (MPa): ≥1.4 6) Thermal shock resistance (times/1,100°C): 5 7) Bulk density (g/cm³): ≤0.5 Extruded filters (ceramic filters): For the filtering of metallic molten polymer, this product has the characteristics of larger specific surface, high mechanical strength, and perfect heat-resistance performance. Based on the case studying of domestic international cast field in recent years, our factory adjusts the prescription and innovate the technique to produce filters products with different appearance specifications, wall thickness, hole type and aperture. Materials: cordierite, mullite, alundum mullite
