Bio‐Based Chitosan as a Green Flame Retardant for Rigid Polyurethane Foam Composites: Enhanced Flame Retardancy, Smoke Suppression, and Mechanical Performance With Experimental and Simulation Validation

ABSTRACT Rigid polyurethane foam (RPUF) composites were modified with bio‐based chitosan (CS) as a green functional additive to replace conventional synthetic flame retardants for building insulation applications. The RPUF/CS composites were systematically characterized by FTIR,...
