In silicone products such as high-temperature vulcanized rubber, mold-making rubber, and sealants, the choice of reinforcing filler directly impacts the mechanical properties and cost control of the final product. IOTA 9002 Precipitated Silica, with its reinforcement performance approaching that of fumed silica, narrow particle size distribution, and excellent dispersibility, becomes an ideal reinforcing filler for high-temperature rubber and silicone rubber products, effectively reducing production costs while maintaining high performance.
Excellent Reinforcement Performance, Approaching Fumed Silica
Made from high-quality silica raw materials, processed to achieve micron-level particle size
BET specific surface area of 140-260m²/g, reinforcement效果接近 fumed silica
Significantly improves the tear strength of silicone rubber, extending product service life
Narrow Particle Size Distribution, Excellent Dispersibility
Uniform particle size distribution provides rare high specific surface area
Good dispersibility ensures uniform distribution in the silicone rubber matrix
Can partially replace fumed silica, maintaining performance while reducing costs
