Product Description

Company Profile

Gesee technology, your chemical expert!
Welcome to Gesee, Our main products  fumed silica, which is divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments.GESEESIL 200 Fumed Silica is a hydrophilic fumed silica with a specific surface area of 200 m2/g. The hydrophilic nature of fumed silica results from the addition of hydroxyl groups to silica atoms directly on the surface of the particle; The hydrophilic fumed silica is now able to bind hydrogen, making it water-dispersible.

Currently we have fumed silica 
GESEESIL-150; GESEESIL-200 for choice.
they are widely using in rubber, sealant, plastic, resin, paint, printing ink, papermaking, medicine, cosmetics, food etc.Hydrophilic silica is used to reinforce and thicken silicone as an anti-slip agent for food and industrial powders, and to thicken non-polar solvents such as xylene, white spirit and styrene.Small particle size, large specific surface area, good thermal stability and low water content

Application

 

1.Reinforcing: Improve the tensile strength, tear strength, toughness and impact resistance of the product;
2.Thickening, improving the product consistency of liquid system, rheological control, thickening without thinning;
3.Thixotropy, one touch change, improve the rheological and thixotropy of liquid systems;
4.Anti caking, promote and maintain the fluidity and anti caking performance of powder particles;
5.Anti sagging: prevent the liquid from flowing and sagging, and improve the flatness of the construction surface;
6.Anti sedimentation improves the adhesion of various systems, effectively prevents layered sedimentation, and is an ideal suspending agent;
Thermal insulation: thermal conductivity and excellent thermal insulation effect;

Fumed silica is a very useful industrial chemical used in a variety of industrial and consumer products. Fumed silica poses a variety of health hazards to workers in various end-use industries and to those using products that use fumed silica. 
1. in various resin additives, medicine, food and other fileds.
2. rubber, sealant, silica gel, adhesive, tile grout etc.
3. paint, coating, UPR,
4. CMP suspension etc;
5. Digital photo paper etc.

1.Paint and coating: as a hexagonal additive, it can effectively prevent pigment filler from settling and layering, improve the weather resistance, scratch resistance, sagging and leveling of the coating;
2.Ink, air silicon has good thickening and sedimentation performance, which can adjust the viscosity of ink and prevent pigment sedimentation.;
3.Resin, improve numerical thixotropy, make it have good tensile strength, bending resistance, milk, heat resistance and other properties;
4.Chemical fertilizer plays the role of adsorption, moisture absorption and anti caking in powder fertilizer and suspension and anti sedimentation in liquid fertilizer;
5.Thermal insulation materials, gas silicon has low thermal conductivity, which makes it have base thermal conductivity and excellent;
6.Adhesive sealant can be used as thickener and thixotropic agent to increase bonding strength and prevent sagging and collapse during fixed line operation;

7.Silicone rubber, air silicon is a very ideal reinforcing agent for silicone rubber, which can greatly improve its tensile strength and tear strength.;
8.Food: gas silicon in powder food can improve fluidity, prevent powder agglomeration and carrier adsorption;
9.Medicine: gas silicon can be used as anti caking agent, drug carrier and excipient of drugs, so as to prolong the efficacy;
10.Toner: improve the fluidity, charge retention and environmental storage stability of toner, and improve the defects such as bottom ash and ghosting during printing;
11.Catalyst carrier: gas silicon has good adsorption, dispersion and high purity, which can effectively improve the catalyst effect. It is an excellent catalyst carrier;
12.Optical fiber: gas silicon has excellent thickening thixotropy, which can effectively improve the filling efficiency of optical fiber filling paste;
