A 150 News | Forum flame retardants exposure to tdCPP appears Widespread At a time of growing debate over the safety and usefulness of flame retardants added to consumer products, 1 new evidence is emerging about the breadth of human exposure to one of the most widely used of these compounds. Two new studies 2,3 document the presence of the flame retardant tris(1,3-dichloro-2-propyl) phosphate ...

BACKGROUND Flame retardant chemicals are used in materials on airplanes to slow the propagation of fire. These chemicals migrate from their source products and can be found in the dust of airplanes, creating the potential for exposure. METHODS To characterize exposure to flame retardant chemicals in airplane dust, we collected dust samples from locations inside 19 commercial airplanes parked ...

The flame retardancy of plywood should be improved as much possible while minimizing the impact on bonding strength plywood. Six commercial retardants and three laboratory synthesized phosphorous nitrogen were selected. E0, E1 E2 grade formaldehyde resins (UF) applied in this study to evaluate effect different curing time resin, strength, retardant performance, emission results show that additi...

A novel flame retardant, zinc hydroxystannate-decorated graphene oxide (ZHS/GO) nanohybrid, was successfully prepared and well characterized. Herein, the ZHS nanoparticles could not only enhance the flame retardancy of GO with the synergistic flame-retardant effect of ZHS but also prevent the restack of GO to improve the mechanical properties of poly (vinyl chloride) (PVC) matrix. The structure...

Enhanced Heat Release Rate (HRR) methodology has been extended to the Mass Loss Calorimeter (MLC) and the Modified Schlyter flame spread test to evaluate fire retardant effectiveness used on wood based materials. Modifications to MLC include installation of thermopile on the chimney walls to correct systematic errors to the sensible HRR calculations to account for radiant energy losses to the c...
