Abstract

ABSTRACTIn this paper, an efficient flame retardant polyurethane foam (PUF) material consisting of phosphorus-halogen flame retardants has been prepared by adding dimethyl methylphosphonate (DMMP) and tris(1-chloro-2-propyl) phosphate (TCPP). The limiting oxygen index measurement and thermal analysis have been used for accessing the flame retardancy and thermal properties of the PUF sample. Thermal decomposition process of the sample and its evolved gaseous products at different temperatures during pyrolyzing have been investigated and identified via thermogravimetric analysis by coupling with Fourier transform infrared spectrometry. Influence of DMMP and TCPP on the evolved gaseous products during pyrolysis has been discussed here.
