Precipitated Silica (silicon dioxide, SiO2)

HS Code : 38249925 | CAS NO. : 7631-86-9

General description:

Precipitated silica is an amorphous form of silica; it is a white, powdery material. Precipitated silica is produced by precipitation from a solution containing silicate salts. The three main classes of amorphous silica are pyrogenic silica, precipitated silica and silica gel.

Precipitated silica
Precipitated silica is a white, powdered type of silica. Precipitated silica is created by precipitating silicate salts from a solution. Quartz sand, a crystalline form of silicon dioxide, is the source of precipitated silica, a synthetic form of amorphous silicon dioxide. There are numerous ways to control the precipitated silica's physical characteristics during the production process, resulting in high-performance products for a wide range of varied end uses.

Precipitated silica uses
1. Precipitated silica is used as an adhesive. It can be used to strengthen bonds and as a thickening and reinforcing agent. When a liquid adhesive comes into touch with a solid surface, the scattered silica particles inside it solidify quickly. Adhesive based on natural and synthetic rubber.
2. It's a component of PVC sheets. Precipitated Silica improves pigment dispersion, works as a separating agent and an absorbent to enhance flow, and gives the compound a dry feel.
3. For textile cots and aprons, precipitated silica is utilised as reinforcing silica.

Application & Usage:

1. Filler, softener and performance improvement in rubber and plastics Cleaning, thickening and polishing agent in toothpastes for oral health care Food processing and pharmaceuticals additive as anti-caking, thickening agent, absorbent to make liquids int.
2. precipitated silica is useful to enhance bond strength and as a reinforcing and thickening agent. The dispersed silica particles within a liquid adhesive harden fast when it is in contact with a solid surface. In both natural and synthetic rubber-based adhesive.
3. Silica provides thixotropy, reinforcement and promotes adhesion as well as serves as extenders, therefore it raises quality and lowers cost.
4. It prevents resin separation and the settling of pigments and heavy fillers.
5. Precipitated silica is used in shoe soles for its resistance to wear and to tearing ,its non-scuffing characteristics and to obtain compounds with light color or even transparent materials.
6. Precipitated Silica is used to prevent cracking and cut the growth of Conveyor Belts and power transmission belts.
7. Precipitated Silica is used to improve pigment dispersion and acts as a parting agent and as an absorbent to improve the flow and imparts a dry feel to the compound.
8. Precipitated Silica is used in Railway Pads.
9. Precipitated Silica is used in Rubber Rollers and Rice Rollers

Is precipitated silica dangerous?
Precipitated silica can absorb a lot of oil or moisture. People who have been in touch with the powder or dust for an extended period may experience a drying impact on their hands or other exposed body regions. This drying effect on the mucosal membranes of the nose and throat has produced nosebleeds on occasion. When the dry skin or mucous membranes are no longer in contact with the powder or dust, they can recover to their natural state. It is suggested to avoid skin dryness in those whose hands come into touch with precipitated silica powder.
