Solvay introduces new grade of HDS at Tire Tech Expo

This week at the Tire Tech Expo in Cologne, Solvay Silica introduced Efficium®, a new grade of highly dispersible silica offering higher productivity and greater flexibility in producing green passenger car and truck tire compounds. According to Solvay, the increased productivity comes from its positive impact on mixing and extrusion throughput, while the increased flexibility is due to its silanization control and reformulation opportunities without compromising on rolling resistance, wear and grip. The new grade was introduced with a presentation by Christian Léger, Global Business Director of Solvay’s Silica Global Business Unit. According to Solvay, Efficium®‘s wider operating window is characterized by lower Mooney viscosity, lower temperature sensitivity, better dimensional stability during extrusion and extended storage life of uncured rubber. All of these advantages result in a more versatile product for a broader range of passenger car, commercial vehicles and heavy-duty truck applications. To meet expected demand beyond current trial and testing by major tire manufacturers, Solvay is making Efficium® HDS globally available from three different production sites consistently with its business continuity management policy.
