Abstract (en)
[origin: WO9724362A1] Certain lignins which are readily available from pulping processes function as a polyol component of an isocyanate system to make foams and urethane plastics. Use of the lignin in this manner provides moisture and flame resistance and produces products having sufficient rigidity. The sodium level must be controlled so that the reaction between the hydroxyl groups and the isocyanates produces products with the optimal properties.
