Utilisation of lignin in the synthesis of polyurethane foam

Ramli Ibrahim, . and Lau Seng, . and Teoh Liang Choo, . and Yap Sook Fah, . (1995) Utilisation of lignin in the synthesis of polyurethane foam. [Proceedings Paper]

Some mechanical properties such as density tensile and compression strength of lignin-based polyurethane foam were studied. These mechanical properties were found to be dependent on the amount of lignin incorporated into the polyurethane foam. The formation of the foam was found to be temperature dependent. Addition of lignin to the polyurethane was found to improve its tensile compression strength and density. At 20 lignin content in the polyurethane the polymer was found to have 100 recovery after 5 minutes compression at 50 deflection. The lignin-based polymer showed increase in compression hardness and density with reaction temperature. The opposite trend was observed for lignin-free polyurethane.

Abstract

Some mechanical properties such as density tensile and compression strength of lignin-based polyurethane foam were studied. These mechanical properties were found to be dependent on the amount of lignin incorporated into the polyurethane foam. The formation of the foam was found to be temperature dependent. Addition of lignin to the polyurethane was found to improve its tensile compression strength and density. At 20 lignin content in the polyurethane the polymer was found to have 100 recovery after 5 minutes compression at 50 deflection. The lignin-based polymer showed increase in compression hardness and density with reaction temperature. The opposite trend was observed for lignin-free polyurethane.
