wet ground mica powder Our wet ground mica powder use good quality mica material, in a manufacturing process with washing, refining, dipping, grinding and crashing, cold-drying, screening, and become a kind of good quality filler. Its unique manufacturing technique retains the mica flakes structure, redius-thickness ratio,higher index of refraction,higher purity,higher whiteness, higher luster, lower sand & iron content etc. The performance of wet ground mica powder highly improve mica’s application in resin and plastics (engineering plastics: PA66, PPR pipe), paint(corrosion protection), rubber, lubricant etc ,improving the product performance and reducing the cost. wet ground mica powderchemical propertySiO2Al2O3K2ONa2OMgOCaOTiO2Fe2O3PH44.5 46.5%32 34%8.5 9.8%0.6 0.7%0.53 0.81%0.4 0.6%0.8 0.9%3.8 4.5%7.8physical propertyheat resistancecolorMohs hardnesselastic coefficienttransparencymelting pointdisruptive strengthpurity650°CSilver white2.5(1475.9 2092.7)×106Pa71.7 87.5%1250°C146.5KV/mm>99.9%Specification(mesh)Bulk density(g/cm3)Whiteness('C)MagneticSand content(%)moisture(%)Oil absorption(g/100g)Ignition lossmaterialcontents(PPM)yA100<0.25>70&>73<80<0.5<0.530-30<4.6YA200<0.2>72&>76<60<0.5<0.535-38<4.6YA325<0.18>75&>80<60<0.5<0.536-40<4.6YA400<0.16>75&>80<60<0.3<0.540-45<4.6YA600<0.16>75&>80<60<0.2<0.540-48<4.6Different sizes from100 mesh to1250 mesh could be provided
