Presentation

Improving lignin dispersion to release its reinforcing potential

Lignin has the potential to act as a reinforcing filler in rubbers and replace carbon black and silica as a sustainable alternative. Typically, the poor dispersion of lignin has hindered the reinforcing properties, however, the results from the latest studies show that the dispersion can be improved with optimal mixing parameters and by choosing the correct silanes. A novel method is used to measure and quantitatively analyze the lignin dispersion.
