Highly Dispersible Silica (HDS) — The Next Generation

Highly Dispersible Silica (HDS) represents a significant advancement in silica technology. Unlike conventional silica, HDS is engineered to disperse more uniformly in rubber compounds, delivering superior performance


Key benefits of HDS:
• Improved wet traction - tan delta values @0°C (a lab predictor of wet traction) are improved by approximately 3%-

• Reduced rolling resistance - tan delta values @60°C are improved by approximately 6%-

• Better wear life - excellent dispersion into reinforcing aggregates with no agglomerates >23 microns-

• Enhanced reinforcement - M300/M100 reinforcement index increased by 10%

Product example: Solvay's Efficium® HDS delivers productivity benefits of up to 30% in mixing and extrusion for truck tire tread compounds, while rolling resistance and wear meet or exceed reference levels

It also offers lower Mooney viscosity, lower temperature sensitivity, better dimensional stability during extrusion, and extended storage life of uncured rubber
HDS is the technology of choice for manufacturers seeking to balance the "magic triangle" of tire performance-wet grip, rolling resistance, and wear life
