Characteristics: High transparency physical characteristics 1. Dry, white micronized powder 2. Porous, large surface area, amorphous, inactive chemical characteristic 3. Tasteless and odorless: 2.15 4. Good dispersion 5. Refractive index: 1.46 6. Surface is hydroxyl, disposed products can be usedChemical characteristics Chemical characteristic inert (it can dissolve in HF and strong bases) Applications: 1. Anti-blocking: plastic films and sheets are often rolled or piled after final
processing. These films tend to adhere to each other at the many points of the contact;
a phenomenon called blocking. Matting agent has proven to be extremely effective
in the prevention of blocking 2. Food additive, pharmaceuticals and cosmetics 3. Adhesion and thickening: matting agent effectively prevents stickiness and separation
while providing emulsifying stability in these applicatio
