Product Description

Product Description

The product is white granule or fluffy powder with high purity and excellent fluidity. It is characterized as high moisture absorption and flow-promotion. It is mainly applied in feed additives, vitamin E and other industries and it is excellent carrier for feed flavoring agent, mould inhibitor, anti-acid agent, antioxidant, silicon-type choline chloride, allicin and other products.In sealants and adhesives, fumed silica plays a major role in rheological control and viscosity strength.When fumed silica is added and dispersed in adhesives and sealants, a silica agglomerates network is formed, agglomerates react with SI-OH and result in hydrogen bonds, thus flowing property is restricted and viscosity increased, thickening property promoted; but,when shear thinning is applied, hydrogen bonds and silica network breaks,viscosity decreases, this allows adhesives and sealants to be applied smoothly; when shear thinning is removed, network restored,viscosity increases, this prevents adhesives and sealants from sagging during curing process.

Application

As an environmentally friendly additive with excellent performance, silica is mainly used in rubber products (including high-temperature vulcanized silicone rubber), feed, paint/coatings, papermaking, pesticides,matting agent and other fields. According to the production method, white carbon black is roughly divided into precipitated white carbon black and fumed white carbon black.
