| Abstract: | The flame retarding activity of four types of chloro-phosphate flame retardantsto pikyurethane flexible foams (PUFF) were investigated in this study by the oxygen indexmeasurement and the horizontal burning test. The flame ratarding mechanism and the influ-ence of the flame retardants on the mechanical properties of polymer materials are dis-cussed. The thermal ageing stability of the resultant flame retarding PUFF was also investi-gated by the accelerated thermal ageing test. |
