Flexible polyurethane foams
Rigid polyurethane foams
Lignin polyols
• Lignin dried and submitted to oxypropylation reaction, using propylene oxide andKOH as catalyst.
• Lignin-based polyols led to the production of foams with lower densities andthermal conductivity, compared to the ones produced with the commercial material.
