Solvay S.A. recently unveiled Efficium highly dispersible silica at the Tire Technology Expo in Cologne, Germany.
Efficium is a reinforcing filler, which allows for higher productivity and greater flexibility in producing green passenger car and truck tire compounds, the company said.
Efficium offers benefits for the automotive industry, Solvay said, allowing for increased productivity due to its impact on mixing and extrusion throughput and adding flexibility thanks to its silanization control and reformulation opportunities without compromising on rolling resistance, wear and grip. Efficium strongly facilitates the conversion from carbon black to HDS compounds.
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, Solvay said. All of these advantages result in a more versatile product for a broader range of passenger car, commercial vehicles and heavy-duty truck applications, the company claimed.
