Properties: This product is white or milky white uniform powder, large specific surface area, with strong adsorption. This product is micron silica gel (SiO2·H2O), odorless, tasteless and non-toxic. Insoluble in water and acid, soluble in hot lye. The product is an X-ray amorphous white powder with a certain particle size distribution. The product can be widely used in polypropylene, polyethylene, non-toxic polyvinyl chloride anti-stick agent; Paint, ink matting agent, thixotropic agent; Semiconductor wafer polishing agent; Anti-caking agent for powder coating and other powders; The coating agent and catalyst carrier of X-ray film can also be used for high-grade furniture coatings, coil coatings, leather products, decorative materials and so on.
Use:
Rubber: eliminate internal tension, delamination and cracking;
Paint, coating: control rheology, anti-light, anti-hanging, anti-ultraviolet, anti-settlement, improve corrosion resistance. Papermaking: ink absorption speed, high whiteness, printing image clear, bright.
Mold use: with excellent dispersion, compatibility, high transparency, high whiteness.

Micro silica gel is widely used in food, beverage, medicine and other industries. Because of its good flow additives advantages, excellent caking resistance, high purity and high inertia, it will not have any impact on the performance of the main agent itself, at the same time, a very low addition amount, a simple addition method, and the use of low-energy mixing equipment. It is mainly used as a lubricant, anti-stick agent and flow aid, especially suitable for the granulation of oil and extract drugs, and the particles made have good fluidity and compressibility. Food and beverage are mainly used as flow auxiliaries and anti-caking agents.
Packing: Lined with plastic bag, external composite bag, 10kg/bag, 15kg/bag. Storage: Store in dry, cool warehouse.
