Rigid spray foam insulation is widely used as wall insulation in construction industry. Replacing synthetic polyether and polyester polyols with bio-based polyol and using water as blowing agent, would provide eco-friendly spray foam which is good for the environment and make buildings a safer place to live. The objectives of this work were to produce sustainable spray polyurethane foam insulation from soy-based polyol, derived from agricultural product and enhance its properties by incorporation of wood and cellulose fibers, a consumer forest product. The composite foam systems and the neat foam prepared in this manner were evaluated in terms of their thermo-mechanical properties, morphological characterization, and also their resistance contribution to overall structural integrity of the buildings against natural shear forces.

520 $a Rigid spray foam insulation is widely used as wall insulation in construction industry. Replacing synthetic polyether and polyester polyols with bio-based polyol and using water as blowing agent, would provide eco-friendly spray foam which is good for the environment and make buildings a safer place to live. The objectives of this work were to produce sustainable spray polyurethane foam insulation from soy-based polyol, derived from agricultural product and enhance its properties by incorporation of wood and cellulose fibers, a consumer forest product. The composite foam systems and the neat foam prepared in this manner were evaluated in terms of their thermo-mechanical properties, morphological characterization, and also their resistance contribution to overall structural integrity of the buildings against natural shear forces.
520 $a Wood fiber and cellulose fiber were incorporated as reinforcement in foaming in three stages, 13php, 26php, and 40php. The fiber size, dispersion and concentration within the matrix affected the reinforcing quality. The interactions and the effects of fiber in composite foams were observed at cellular level by Fourier transform infrared and scanning electron microscopy to evaluate their performances. The results indicated incorporation of fiber had an impact on the cell morphology of the composite foam system as compared to the non-fiber foam. The cell structure became more uniform while cell density was increased proportionate to the fiber concentration. Resin found to be compatible with fiber at interfaces but, the viscosity of matrix polymer increased with addition of fiber. The viscosity increase was 20% under 26php fiber concentration. The thermo-mechanical properties of the composite foam systems were improved to some extent at lower fiber concentration, under 26php, due to less impact of viscosity. Cellulose fiber performed better as reinforcement than that of wood fiber due to superior compatibility, higher strength and better fiber quality.
