OCI KONASIL KP20 Hydrophilic Fumed Silica

OCI KONASIL KP20 is an imported hydrophilic fumed silica from South Korea, belonging to KONASIL series. Refined by high-temperature flame hydrolysis, it is a high-purity amorphous white fluffy powder with balanced thixotropy, thickening, anti-settling and reinforcement, suitable for various polymer systems and high-quality functional additives.

Features Of OCI KONASIL KP20 Hydrophilic Fumed Silica

  1. Balanced thixotropy and thickening - Precisely control system rheology, stable anti-sagging and anti-settling effects, suitable for various construction scenarios

  2. Efficient elastomer reinforcement - Significantly improve the tensile strength, tear strength and durability of silicone rubber and elastomers

  3. High purity and low impurity - SiO₂ content ≥99.8%, extremely low impurity content, ensuring product batch stability and thermal-electric insulation

  4. Wide system compatibility - Good compatibility with silicone rubber, acrylic, PU, PVC plastisol and coating systems, easy to disperse

  5. Easy powder processing and storage - Fluffy without coarse particles, improve powder fluidity, prevent caking, easy for feeding and long-term storage

Typical Applications Of OCI KONASIL KP20 Hydrophilic Fumed Silica

  1. HTV/RTV silicone rubber - Efficient reinforcement, improve product mechanical properties and resilience, suitable for sealing and shock absorption products

  2. Sealants and adhesives - Thixotropic thickening and anti-settling, optimize workability and bonding strength, suitable for various sealing and bonding scenarios

  3. Industrial coatings and printing inks - Anti-sagging, stabilize the system, improve film fineness and printing uniformity

  4. Acrylic/PU/PVC plastisol - Rheology adjustment, improve processing and molding performance, enhance product surface texture

  5. Resin gel coats and composite materials - Enhance mechanical properties, and improve product insulation, suitable for medium and high-end processing needs
