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 ratiohigher index of refractionhigher purityhigher 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. chemical property SiO2 | Al2O3 | K2O | Na2O | MgO | CaO | TiO2 | Fe2O3 | PH | 44.5~46.5% | 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% | 7.8 |
