Antifoaming agents

Antifoaming agents

Hydrophobic silica can be added as a nucleating agent to antifoam agents to improve the antifoaming effect because the aggregate particles of silica interfere with the stability of the foam film. The surface silanol groups of silica can be treated by customers themselves depending on the intended use.

Recommended grades

Nipsil SS-210A, Nipsil G-300, NIPGEL AZ-204

Examples of uses

Various antifoaming agents

Fluidity modifiers

Fluidity modifiers

Silica aggregates cover powders and pellets, preventing them from sticking to each other and improving their fluidity. The silanol groups on the surface of silica also have a moisture absorption effect, preventing caking due to moisture.

Chemical raw material

Chemical raw material

The purity of SiO₂, which constitutes silica, is as high as 99% or more, making it suitable for use as a chemical raw material. It is also chemically stable and nonflammable, and has a high melting point of 1,710°C, making it suitable as a raw material for applications requiring heat resistance.

Recommended grades

Nipsil LP, NIPGEL CX-200

Examples of uses

Fire-proof equipment, catalytic components

Thickener

Thickener

Silica forms a structure with silanol groups in liquids, which imparts a thickening effect. The thickening effect is further enhanced when the silica pores absorb the liquid.

Adsorbent

Adsorbent

A wide variety of substances can be adsorbed by using physical adsorption through silica pores and chemisorption through silanol groups on the silica surface.

Recommended grades

NIPGEL AY-002, Nipsil TB-5012, Nipsil SS-50B, etc.

Examples of uses

Toothpaste, gel paste, soft feel paints

Anti-blocking agent

Anti-blocking agent

Aggregate silica particles form unevenness on the film surface, preventing films from sticking to each other (blocking). Gel-type silica is recommended because its aggregate particles do not collapse easily during mixing and stretching during film production.
Anti-blocking agent

Recommended grades

NIPGEL AZ-200, NIPGEL BY-200

Examples of uses

Film coatings, paper coatings

Sustained release agent

Sustained release agent

The active ingredients impregnated in the silica pores gradually diffuse to maintain effectiveness.
