Thermal Degradation and Physical-mechanical Properties of Lignin-filled Rigid Polyurethane Foams

Abstract

Nowadays, the synthesis of polymers from renewable resources, including polyurethane foams, has been actively investigated. In this work the potential application of lignin (CIMV, France) as non-reactive filler in tall oil amide (OH = 269 mg KOH/g, H2O = 0,2 wt.%) based rigid PU foams is studied. It was concluded that introducing lignin to rigid PU foams systems can increase physico-mechanical properties of foams
