wet ground mica powder

1. Our Wet Mica Powder use good quality mica materials,manufacturing process with washing,refining,dipping,grinding and crashing,cold-drying,screening,finally get a good quality filler. 2.It is unique manufacturing technique retains the mica flakes structure,redius-thickness ration,higher index of refraction,high purity,higher whiteness,higher luster,lower sand and iron content,etc. 3.The above performances highly improve mica ’ s applications in resin and plastics,paint and coating,rubber,lubricant.etc. Specifications of Mica Powder Physical Property Heat Resistance 65 0℃ Color Silver White Moh ’ s Hardness 2.5 Elastic Coefficient (1475.9-2092.7) × 106Pa Transparency 71.7-87.5% Melting Point 125 0℃ Disruptive Strength 146.5KV/mm Purity 99.5%min Chemical Property SiO2 48.5-50% CaO 0.4-0.6% Al2O3 32-34% TiO2 0.8-0.9% K2O 8.5-9.8% Fe2O3 3.8-4.5% Na2O 0.6-0.7% PH Value 7.8 MgO 0.53-0.81% Items Bulk Density (g/cm3) Magnetic Material ppm Sand% Moisture% Oil Absorption (g/100g) Loi W-100 0.25max 80max 0.5max 0.5max 30-30 3.6max W-200 0.20max 60max 0.5max 0.5max 35-38 3.0max W-325 0.19max 60max 0.5max 0.5max 36-40 3.0max W-400 0.18max 60max 0.5max 0.5max 36-40 3.0max W-500 0.16max 60max 0.3max 0.5max 40-45 3.0max W-600 0.16max 60max 0.2max 0.5max 40-48 3.0max Items W-100 W-200 W-325 W-400 W-500 W-600 Bulk Density (g/cm3) 0.25max 0.20max 0.19max 0.18max 0.16max 0.16max Magnetic Material ppm 80max 60max 60max 60max 60max 60max Sand% 0.5max 0.5max 0.5max 0.5max 0.3max 0.2max Moisture% 0.5max 0.5max 0.5max 0.5max 0.5max 0.5max Oil Absorption (g/100g) 30-30 35-38 36-40 36-40 40-45 40-48 Loi 3.6max 3.0max 3.0max 3.0max 3.0max 3.0max
