Hydrothermally Carbonized Lignin as Sustainable Filler for Tire-Tread Application
An increasing emphasis of the tire industry on sustainability can be met with new fillers. Based on this, the modification of lignin was developed as it offers abundancy, eco-friendliness and a renewable nature.
This study focuses on investigating the reinforcing behavior of a TESPT modified lignin-based filler in a SSBR/BR blend in comparison to CB and silica/TESPT. With mechanical strength comparable to the reference compounds, the lignin-based filler compound exhibits significantly improved dynamic properties. Tailor-made recipes allow to vary the mechanical and dynamic properties to the desired level and to replace conventional fillers.
