Highly dispersible fumed silica specifically engineered for natural and synthetic rubber compounding.
Optimized particle morphology to enhance reinforcement, tensile strength, and abrasion resistance in vulcanized rubber.
Low moisture content ensures consistent processing and reduced scorch risk during mixing and curing.
Excellent compatibility with sulfur-cured systems and widely used accelerators (e.g., CBS, TBBS).
Consistent batch-to-batch quality supported by strict ISO 9001-certified manufacturing controls.
Tread compounds for high-performance passenger car and truck tires.
Green tire formulations requiring low rolling resistance and improved wet grip.
Dynamic rubber components including engine mounts, bushings, and vibration dampers.
Industrial rubber goods such as conveyor belts, hoses, and seals demanding resilience and fatigue resistance.
Specialty elastomer blends incorporating solution-styrene butadiene rubber (S-SBR) and polybutadiene rubber (BR).
