Abstract: This article describes a thorough investigation of the physical and thermal properties of lignin based polyurethane building materials. The materials were created with lignin polyol and isocyanate. Factors investigated included compressive strength, thermal conductivity, burning behaviour, and morphology. The authors determined that compressive strength depended on the amount of lignin in the material, the sample containing 30% lignin had the highest strength. The thermal conductivity of the sample with the highest compressive strength was 0.02517 W/mK. Burning experiments revealed that a flame retardant char did develop to act as a barrier. The authors concluded that lignin is a viable alternative to use in polyurethane building materials.
