Luca GianniniLuca Giannini, after graduating in Chemistry at the University of Pavia, got his PhD from University of Lausanne. Luca is co-author of more than 22 patents, 30 scientific papers and one book chapter in “Rubber technology, Nanomaterials and Nanocomposites”. He joined Pirelli Tyre SpA in 2003, working since then on R&D projects in the field of rubber nanocomposites and on new tyre products, leveraging innovative materials and processes, as Self Sealing and Noise Suppression System.
Lignin NR composites for high performance sustainable tires
This presentation will illustrate the introduction of lignin in compounds for high performance tyres, in particular following two directions: 1) surface chemistry modification of phenols and carboxy groups to boost lignin-rubber interactions and 2) latex compounding targeting to evenly disperse in rubber. Lignin derivatives were used in partial replacement of carbon black, resulting in good dynamic reinforcement and tensile strength before and after aging.
