AB Lignin is demonstrated as an unprecedented reinforcing material that tailors therheological and cushioning properties of castor oil-based polyurethane elastomers,expanding their viscoelastic moduli by four orders of magnitude. The tensile strain atbreak was triplicated in the presence of lignin while the Young modulus and the stressat break were enhanced 17- and 7-fold, respectively. Remarkably, in compression tests,lignin addition increased the stresses at break by more than 88-fold, whereas the strainat failure shifted from 50 to 93%. Dynamic mechanical compression tests indicatedoutstanding cushioning and resistance performance. Overall, the results demonstrate aperformance not reached before for biosourced elastomeric materials, fitting thedemands of a wide range of applications.
