Water Solubility:insoluble
Packing:10kg/bag or 20kg/bag
The purity of SiO2 in TSA series products reaches to 99%,and special method is adopted for surface treatment so that its refraction index reaches 1.47,being close to that of colophony,i.e. 1.40~1.60,which greatly improves its transparency in coatign film and avoid the low-grade delusterant powder's problem of turning white and blue on the surface.
Marble, ceramics Industry: Make products become more white, and to fill the hairlike gap action in marble, ceramics.
Cosmetics Industry: It can increase bath products the viscosity of the product, reduce the greasy feeling, improve refreshing.
Silicon Rubber: Improves silicon rubbers durability, rebound rate, and anti-distortion performance.
Plastics Industry: Improves plastics tenacity, strength and prevents water absorption.
Coating Industry: Prevents agglomeration and drip, thixotropic additives. Increase denseness and smoothness of paint.
Medicine Industry: Increase denseness, floating, carrying function in medicine. It also can be used as the pesticide powder and anti-agglomeration.
