Abstract

In this study, CaCO3 nanostructures have been used to enhance the flame retardancy of vegetable oil based rigid polyurethane foams (RPUF). RPUFs were prepared by using polyol derived from transesterification reaction of castor oil. Prepared foams were characterized by cone calorimeter for their fire behavior. Results showed decrease in peak of heat release (PHRR) by the incorporation of nano calcium carbonate. Additionally, total heat release (THR), smoke production rate (SPR) and total smoke release (TSR) were also found to decrease remarkably. So, CaCO3 nanostructures have great potential as an additive to enhance flame retardant properties in vegetable oil based RPUF.
