LUDOX(R) HS-30 COLLOIDAL SILICA - Nature

Open Data Verified Data

The precipitated silica is a white amorphous fine powder composed of secondary particles in which primary particles are aggregated into branched chains. The primary particles are generally between 10 and 15 nm, and the precipitated silica aggregated therefrom has a large internal surface area. The silicon atoms in the surface layer form surface hydroxyl groups due to unsaturated valence bonds, and the types of the silicon atoms include dihydroxyl groups, adjacent hydroxyl groups, and Isolation hydroxyl groups. Light weight, relative density of 2.32~2. 65. Melting point 1750 °c. Soluble in caustic and hydrofluoric acid, insoluble in other acids, water and various solvents. High temperature resistance, non-flammable, water absorption, good electrical insulation. It shows chemical inertness to The Matrix and active components and additives. Good compatibility with vitamins, hormones, fluorides, antibiotics, enzymes and many active ingredients commonly used in cosmetics. Due to the porosity and large specific surface area, there is a large dispersion force in the raw rubber. Filling in rubber shows high reinforcement.

LUDOX(R) HS-30 COLLOIDAL SILICA - Use

Open Data Verified Data

used as a reinforcing agent for natural rubber and synthetic rubber. The reinforcing effect of rubber mainly depends on the strength of the actual joint and force between the filler and the rubber and the effective area of the filler. The hydroxyl group on the surface of the precipitated silica has affinity with the rubber, which makes the rubber molecule form a certain bond with the surface of the filler particle, and therefore has a good reinforcing property. Mainly used in color rain shoes, sports shoes, travel shoes, transparent rubber soles and other rubber shoes manufacturing, rubber tire manufacturing and off-Valley rubber roller. In addition, fillers for synthetic resins, thickeners for Inks, pharmaceuticals and cosmetics, Matting agents for toothpaste thickeners, main aids for weight reduction of newsprint, and the like can be used.
