Affect of Brominated Flame Retardant on the Flexible Polyurethane Foam
Abstract:
Different flexible polyurethane foams (FPUF) were prepared with one step method. Combustion performance of them were tested throughout oxygen index (OI), cone calorimeter (Cone). The results showed that flame performance prepared by 10% wt brominated flame retardants, and 10% wt MPOP was better. In irradiance 30kW/m2, sample thickness 50mm conditions, heat release rate peak seprarately decreased to 284.0 kW /m2 and 270.8 kW /m2. In the coordination of N and P, the FPUF adding MPOP showed ideal flame retardancy .It is worth noting that when the content of MPOP exceeds 10%, the physical performance decreased rapidly with the increases of brittleness and hardness.
