Hjsil® 380 is a high-purity hydrophilic fumed silica with a specific surface area of 380 m²/g. This white colloidal powder is designed for a variety of applications, particularly in the plastics, elastomers, and coating industries. It offers excellent transparency, rheology control, and flow properties, making it ideal for formulations requiring precise viscosity management and stability. Hjsil® 380 is highly effective in RTV silicones, Liquid Silicone Rubber (LSR), and unsaturated polyesters (UPE), as well as in gelcoats.The product enhances the performance of formulations by providing anti-settling, anti-sagging, and anti-caking benefits. It also acts as a reinforcing filler and a thickener, improving the overall physical properties of the final product. Available in bags, this silica is used in a wide range of applications, including cable accessories, coatings, and elastomer products, where superior rheological properties, anti-sagging, and anti-settling features are crucial.
