ABSTRACT:
Natural sources like starch and lignin used during manufacturing of polyurethane
(PU) foam have been used extensively from last decades and replaced
petro-chemical based PU foam due to their lower environmental impact, easy
availability, low cost and biodegradability. Bio-renewable sources, such as lignin
which is an abundant, underutilized component of cellulosic biomass,
constitute a rich source of polyol which are being considered as polyol for the
production of “eco-friendly and bio-degradable” PU foam. Lignin was mainly
used for production of high fungal degradable polyurethane foams, followed
by elastomers as well as wood adhesives. This review paper will focus on the
progress of research in lignin based polyurethane materials for foam application.
