Description:

Precipitated Silica plays a crucial role in the formulation of silicone rubber. It serves as a reinforcing agent, significantly enhancing the mechanical properties, tensile strength, and elasticity of the rubber. Silica improves the heat resistance and durability of silicone rubber, making it suitable for high-temperature applications. Additionally, it enhances the material’s tear resistance and aging properties, ensuring longevity in various environments. Silica also aids in controlling viscosity during processing, allowing for better moldability and extrusion. Its use in silicone rubber contributes to improved surface finish and stability, making it ideal for applications in automotive, medical, and industrial sectors.
