Application area:
1: Used in coatings and paint industries: Primarily serves to thicken, reduce gloss, prevent sagging, inhibit sedimentation, enhance scratch resistance, improve washability, and withstand high temperatures, while enhancing film properties, aging resistance, and hydrophobicity.
2: Applied to rubber products: Boosts multiple mechanical properties including strength, tensile resistance, tear resistance, wear resistance, and corrosion resistance. Significantly improves flexibility, aging resistance, and metal interface adhesion between rubber products and metals, while enhancing adhesion.
3: Activated silica powder material. Combines with polymer materials to form uniform films, improving stone impact resistance and corrosion resistance in paint coatings. Its washability is enhanced several times over, making it ideal for industrial paints and premium latex paint applications.
4: Used in specialty ceramics: Including honeycomb ceramics and ceramic catalysts for desulfurization and denitrification processes.
5: It is the basic raw material for producing circuit boards, insulating materials, magnetic materials, solar products, electronic components, optical fibers, precision optical instruments and electronic components; it is widely used in aerospace, national defense, electronics, optical fiber communication, optical instruments, laser and other high-tech fields.
6: The production of purified organic silicon, silicone oil, and metallic silicon (Si) is primarily used for manufacturing organic silicon products, producing high-purity semiconductor materials, and formulating specialized alloys. Modern large-scale integrated circuits in semiconductor manufacturing are almost entirely made from high-purity silicon, which also serves as the primary raw material for optical fiber production.
7: Basic raw materials for the production of various glass: it is the main raw material for the production of plate glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and special anti-radiation glass
8: Ultra-fine silica dioxide used in silicone sealants enhances fracture strength, bonding strength, elongation at break, and aging resistance. It ensures a smooth, bubble-free surface with excellent shape retention, extended shelf life, and rapid curing. Shanghai Huizheng Company maintains strict quality control throughout raw material procurement and product manufacturing, guaranteeing consistent product quality that has earned the trust of clients.
