GRADE-SUPER
Distinctive Feature
Stability: hydrophobic and chemically inert, not soluble in water.
Low Mohs Hardness: softest mineral on earth, slippery feel, low abrasive.
Lamellarity: barrier property, dimensional stability.
Organophilic: affinity for certain organic chemicals and absorption properties are key in a number of applications.
Our advantage
1. High whiteness, high purity, high lamellarity, low heavy metal content, asbestos-free.
2. Large particle size scope from 325 mesh to 3000 mesh and with many types suit for different needs.
3. Product meets cosmetics grade and medicine-food grade
