As Flatting and Thickening
Silica for Coatings, Paints, Inks
JS-280 precipitated silica use a special manufacturing technique and features high transparency, high oil absorption, high specific surface area, large pore volume, good matting performance, and good anti-settling properties. It is widely used in the paints, coatings, and inks industries. Adding silica will improve the viscosity of coatings and paints, thus enhancing the convenience in using these materials.
Silica for Adhesives and Sealants
JS-681, JS-682 precipitated silica are characterized by high dispersion, high reinforcement and high transparency. Its use in adhesives and sealants can effectively enhance their reinforcement and thixotropic properties, increase their viscosity, as well as improve their flowability to prevent caking. Because of its small particles, it can also improve the leakproofness and anti-seepage properties of adhesives and sealants.
As Carrier and Free-Flow
Silica for Food Additive
JS-96 precipitated silica has properties such as good fluidity, high porosity, and strong adsorption. It is used in the food industry as carrier for its thickening, anti-caking, and anti-mildew functions. This product is suitable for the mechanized and automated production process in the food industry, and it can also be applied to improve food variety and taste.
Silica for Feed Additives
JS-95 is a favorable carrier for feed additives. It is used to convert liquid animal feed ingredients and additives into free-flowing dry powder and premixes. Using silica carrier ensures the high loading of animal feed ingredients and additives as well as the loading consistency. Feed manufacturers will also be able to benefit from the more efficient mixing and processing in production as a result of the silica carrier use.
Silica for Agricultural and Industrial Chemicals
JS-260 precipitated silica has high transparency, high oil absorption, and high dispersion. It is used as carrier or diluent/disintegrant in agrochemical products such as pesticides and high-efficiency spraying fertilizers. Water dispersible granules using silica as disintegrant will have greater suspension rate and long-lasting effect, because the ultra-high surface area of silica possesses properties of high absorption force, easy suspension, good affinity, and chemical stability.
As Reinforcing Filler, Functions Enhancer, Modifiers for Rubber
Silica for Tires
The JS-185 series of high-dispersion and high-reinforcement precipitated silica are used in tires to effectively improve tire performance. This application features advantages including:
1. Reduced rolling resistance of tires which leads to lower fuel consumption, and improved wet traction and safety performance;
2. Enhance processability of tires with superior tensile strength, tear strength, elongation at break, etc;
3. Lower cost of production due to the replacement of carbon black by precipitated silica.
Silica for Industrial Rubber/Footwear
Major characteristics of JS-185A, JS-185B, JS-185C, JS-185GR precipitated silica include high reinforcement property, good tear strength, and good abrasion resistance. When applied in rubber products, it gives them excellent physical and processing properties. It is mainly used in the shoe soles, rubber hoses, and other rubber industries.
Silica for Silicone Rubber
JS-130, JS-160 precipitated silica uses low-iron sodium silicate as raw material, and features high purity and transparency, low iron-content, good anti-yellowing and reinforcing properties, etc. It is suitable for the silicone rubber industry. Adding silica will effectively improve the tensile strength and vulcanizing properties of silicone rubber.
Speciality Silica
Hydrophobic Silica JS-681/682
As a mixed organic-inorganic material hydrophobized with organic dressing agent in the precipitated solution, the hydrophobic precipitated silica we produce has the following characteristics: high surface activity, low hygroscopicity, enhanced dispersibility in organic medium and excellent polymer compatibility. And it also has the rheological capability to adjust the polar system, add the transparent/semi-transparent characteristics for rubber products.
Applications of hydrophobic precipitated silica
Rheological agent: separant for emulsion, anti-settling agent for paints/coatings/inks/toners, thickening agent, thixotropic agent, anti-block agent for plastic film;
Powder glidant: for powder extinguishing agent and powder coats;
Granula agent and dispersion agent for pesticides;
Carrier for explosive;
Thickening agent for Adhesives and various kinds of polar liquid like epoxy resin;
Defoaming agent:
Abrasive agent for tooth paste;
Reinforcing agent for organic silica elastomer;
With the hydrophobic and anti-corrosion characteristics, the hydrophobic precipitated silica can also enhance the insulating property for cables and cords. And with the high reinforcement, the hydrophobic precipitated silica is widely used in the industrial plastic, modified plastic and silicon rubber.
