Keywords： rigid polyurethane foams

Rigid polyurethane foams were fabricated with five kinds of liquefied sugarcane bagasse polyols(LBP).The foams derived from sugarcane bagasse were investigated by thermogra-vimetric analysis(TGA),and the thermal degradation data were analyzed using the Coast-Redfern method and Ozawa method to obtain the reaction order and activation energy.The results indicate that the sugarcane bagasse-foams exhibit an excellent heat-resistant property,whereas their pyrolysis procedures are quite complicated.The reaction as first order only takes place from 250 to 400℃,and the pyrolysis activation energies vary from 20 to 140 kJ/mol during the whole pyrolysis process.
