Researchers use kenaf to create bio-based polyols for use in rigid polyurethane foam

A team at Universiti Kebangsaan Malaysia’s Bioresources and Biorefinery Laboratory is exploring another potential source of bio-based polyols. They have been studying polyols extracted from kenaf and how they perform when making polyurethane foam. Kenaf was liquefied using PEG400/Gly as solvent. This was then used to make rigid polyurethane foams with a range of different isocyanate indices and the effect of these indices on the foaming…
