In DIC, the processes of coagulation and fibrinolysis are dysregulated, and the result is widespread clotting with resultant bleeding. Regardless of the triggering event of DIC, once initiated, the pathophysiology of DIC is similar in all conditions. One critical mediator of DIC is the release of a transmembrane glycoprotein called tissue factor (TF).
Rigid polyurethane and polyisocyanurate foams will, when ignited, burn rapidly and produce intense heat, dense smoke and gases which are irritating, flammable and/or toxic. As with other organic materials the most significant gas is usually carbon monoxide. Thermal decomposition products from polyurethane foam, consist mainly of carbon monoxide, benzene, toluene, oxides of nitrogen, hydrogen cyanide, acetaldehyde, acetone, propene, carbon dioxide, alkenes and water vapor.
Flexible Polyurethane Foam Flammability. Flexible polyurethane foam (FPF) is an organic material and, like all organic materials, is flammable. Organic materials include a variety of common substances including wood, paper, cotton, wool, nylon, polyester, polyethylene, and polystyrene and other plastic materials.t is the responsibility of the foam buyer to select the proper FPF to meet specific end-use requirements. It is the end-user's responsibility to comply with any applicable building code, occupancy requirements and flammability standards and to take reasonable precautions to protect FPF products from ignition.
