Abstract: The preparation techniques and properties of lignocellusic-based polyurethane as well as the progress on enhancement of their flame resistant properties were reviewed. The lignocellusic-based polyurethane materials can be synthesized from diisocyanate and bio-polyol. The bio-polyol could be obtained from the degradation products of plants. Biodegradability and thermal stability of lignocellusic-based polyurethane have been improved more significant than conventional polyurethane products. The addition of fire retardant into polyurethane formulations or flame-retardant polyols were applied to improve flame retardancy. The phosphates were utilized commonly as flame-retardants.

Key words: plant, polyurethane, phosphorus-based flame retardant
