According to a research report by Market Insights Inc., the global fumed silica market is valued at US$1.59 billion in 2020, and is expected to exceed US$2.3 billion by 2026, a compound year from 2021 to 2027. The growth rate is 5.4%.

Fumed white carbon black is a white powder formed during the manufacturing process of elemental silicon. This product can act as a thixotropic agent, rheology modifier, viscosity regulator, thickener and anti-settling agent, making it an attractive choice for various manufacturing companies. Not only that, it can also improve the operating efficiency of the production process of pharmaceuticals, cosmetics, silicone rubber, adhesives and sealants, and paints and coatings. Fumed white carbon black can improve and maintain the quality of products manufactured in the above-mentioned industries. Because of this series of beneficial characteristics, the consumption of fumed silica will increase sharply in the next few years.

The report predicts that by 2027, the market share of hydrophobic vapor phase silica will increase at a compound annual growth rate of 6%. Compared with hydrophilic fumed silica, the price of this type of product is higher. The price difference between the two fumed silica is mainly due to the additional processing required for hydrophobic fumed silica. Hydrophobic vapor phase white carbon black is a treatment grade vapor phase white carbon black prepared by reacting reactive silanes (such as hexamethyldisilazane or chlorosilane) with hydrophilic white carbon black. Due to the presence of short-chain or long-chain organic groups, these groups are anchored on the surface of fumed silica, which makes it have water-repellent properties. When used for silicone reinforcement, it will not allow polar solvents and isocyanates. , Alcohols, epoxy resins and polyurethanes, etc. become thicker.

Silicone elastomers occupies an important share in the market size of fumed silica. It is used in high temperature vulcanized silicone rubber (HTV) to improve reinforcement, dispersion, sag resistance, surface quality and service life. In the production process of silicone elastomers, fumed silica is added to improve toughness, tensile strength, modulus, elongation and hardness. In addition, it also helps to improve thermal stability, flame retardancy, extrudability and transparency.
