Alkaline Bio-Based Silica
As a premier manufacturer and supplier in China, we offer alkaline bio-based silica, a premium inorganic silicon compound derived from renewable resources such as rice husks and straw. Our advanced CO2 acidification process yields a white, non-toxic, amorphous micro-pearl substance with exceptional properties. This silica is an essential additive for rubber and coating applications, providing benefits like improved dispersion, chemical stability, and high-temperature resistance. We focus on delivering high-purity materials that meet stringent industry standards.
- Enhance Rubber Vulcanization: Our alkaline bio-based silica, with a pH of 8.5-10.5, actively promotes rubber vulcanization, potentially shortening curing times without the need for additional modifiers.
- Improve Mechanical Strength: The presence of surface hydroxyl groups on our silica significantly boosts the mechanical strength of rubber products, reducing compression permanent deformation and ensuring high resilience.
- Versatile Application in Rubber: Ideal for light-colored rubber products, including fluororubber, and high-strength, low-compression deformation NBR oil seals, O-rings, hoses, and printing rubber rollers.
- Sustainable & Eco-Friendly: Produced using renewable resources and a CO2 acidification process, our silica contributes to carbon reduction targets, making it a responsible choice for environmentally conscious manufacturers.
