Highly dispersible precipitated silica with optimized particle morphology for enhanced reinforcement in rubber compounds.
Low abrasion loss and excellent dynamic performance, contributing to improved tire tread wear resistance.
Controlled surface chemistry ensuring strong polymer–filler interaction in silica–rubber systems.
Free-flowing granular form (GR) enabling dust-free handling and consistent feeding in high-speed mixing lines.
Consistent batch-to-batch quality certified under ISO 9001 and compliant with REACH and RoHS requirements.
High-performance passenger car tire treads requiring low rolling resistance and high wet grip.
Truck and bus radial (TBR) tire treads demanding extended service life and thermal stability.
Specialty rubber compounds for industrial hoses, conveyor belts, and anti-vibration mounts.
White or colored rubber goods where high brightness and low metal content are critical.
