Preparation of bio-based polyurethane foams from liquefied cassava bagasse and polymeric diphenylmethane diisocyanate

Cassava bagasse (CB) was liquefied using polyethylene glycol to prepare polyol. The liquefied cassava bagasse (LCB) was reacted with polymeric diphenylmethane diisocyanate (PMDI) to produce novel bio-based polyurethane foams (PUF) via a one-pot process. The results showed that the density of the LCB-PUF was in the range of 0.027 to 0.039 g/cm3. When the LCB was used to instead of polyether polyol with a replacement ratio rising from 20% to 100%,...
