Precipitated Silica

Precipitated silica from rice husk is a high-purity (>98%), amorphous white powder extracted via alkali leaching of rice husk ash (RHA) and subsequent precipitation with acid or CO₂. It is a sustainable, cost-effective, and sustainable alternative to conventional fillers, commonly used in rubber, tire, paint, and cosmetic industries due to its high surface area and reactivity.

High levels of purity

Contains 90% to 99.9% silica (SiO2) depending on the grade

Particle Size

Nano-scale and ultra-fine particles

Reduced Carbon Footprint

Production processes in 2026 can reduce CO₂ emissions by approximately 40% to 60% compared to traditional mined-sand silica.

Closed-Loop Manufacturing

Utilizing processes like IPSIT

Eco-Friendly Sourcing

Produced from renewable agricultural waste, reducing landfill reliance and agricultural byproduct disposal challenges.

Surface Area

High specific surface area
