To strive towards sustainability in rubber industry’s value chain, renewable resources are of great importance. The replacement of
petroleum based reinforcing fillers by Hydro-Thermally Treated (HTT) lignin is a promising approach as it is from a renewable
and abundantly available bio-based material.
This study presents the reinforcing behavior of unmodified- and modified-HTT lignin in a SSBR/BR blend. It is demonstrated that
the morphology of the modified HTT lignin in the rubber matrix, investigated by AFM explains the in-rubber behavior. The
vulcanizate properties achieved illustrate that the mechanism of this type of lignin positions itself somewhere in-between carbon
black and silica. The presentation will focus on the specific interactions of the HTT lignin with the used elastomer blend in the
perspective of its own merits as a reinforcing agent. The performance achieved highlights the opportunities of this new bio-based
reinforcing filler. The rubber reinforcement gained with this new material underlines that a sustainable bio-material can contribute
to performance of rubber compounds.
