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

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, thermogravimetric analysis (TG), limiting oxy...

Synergistic flame retardancy, thermal stability and reinforcing effects of silk fibroin/cobalt phytate on rigid polyurethane foam composites

Abstract Rigid polyurethane foam (RPUF) is utilized extensively in many different sectors because of its special benefits. Nevertheless, this also emphasizes how crucial its flame-retardant qualities are. In this paper, a simple and green coprecipitation method was used to prepare cobalt phytate (PA-Co) flame retardant...
