Sepiolite
Introduction of Sepiolite:
Sepiolite is a clay mineral of fibrous magnesium silicate. It is a hydrous aluminum-magnesium silicate with chain structure. Usually the colour is white, light gray, pale yellow etc. Sepiolite is opaque and lusterless. The specific gravity of sepiolite is 2-3.2, the hardness is 2-2.5, and melting point is 1500-1700℃.
Properity of Sepiolite:
1)Sepiolite is kind of high-performance non-metallic mineral,with the largest specific surface area up to 900m2/g.
2)Sepiolite is innoxious,flavourless and high temperature resistance.
3)Sepiolite has low shrinkage rate,good plasticity and insulation,high salt-resistance etc.
4)Sepiolite has excellent quality of adsorption,decoloration,heat insulation and disperse.
Chemical Composition of Sepiolite:

Size: SG2040, SG152, SG148, SG-A1.
Application of Sepiolite:
Sepiolite is an ideal material to replace chrysotile asbestos. Sepiolite is widely used for cement, rubber, braking, friction, seals, heat insulation materials, coating, textile, adsorbent, and fire retardant etc.
1) Friction materials: brake pads, brake gasket and brake lining etc.
2) Thermal insulation materials: fire proof, heat preservation, wall coating materials.
3) Sealing materials: rubber board.
4) Fiber cement materials: fiber cement pipe, fiber cement pressure board, plastic cement.
Packaging Method:
pp bag,5kg/bag,10kg/bag,20kg/bag,25kg/bag or as customer’s request.
