Fumed Hydrophilic Silica is a white amorphous nano-scale powder produced via vapor-phase hydrolysis. Its surface is rich in hydroxyl groups, providing excellent hydrophilicity and dispersibility. It significantly improves the tensile strength, tear strength, and wear resistance of silicone rubber, making it a core reinforcing agent for high-end seals and key rubber components. In UV coatings and anti-corrosion coatings, it effectively adjusts thixotropy, prevents pigment sedimentation, and ensures uniform, anti-sagging films. In epoxy adhesives, it enhances viscosity and cohesion for stable bonding. With high purity, low impurities, and compliance with EU environmental standards, it offers consistent performance.
