High-disperse silica
EXTOL production and research and development of high-dispersible silica, including micro pearl and granular form. Mainly used for winter tires, car tires, four seasons tyres, high performance tyres and truck tyres. It can effectively reduce the rolling resistance of the tire and improve the wet skid resistance and wear resistance of the tire. Thus improve the controllability and service life of tires, reduce fuel consumption, better meet the needs of "green tires".
822MP/GR used in winter tires (snow tires and wetland tire).
833MP/GR, 860MP/GR, 870MP/GR used in car tires and season tires.
900MP/GR used in high performance tires and truck tires.
