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.
p-Xylene is a colorless, flammable liquid that is insoluble in water with the chemical formula C 8 H 10 or C 6 H 4 (CH 3) 2. p-Xylene has a boiling point of 138.35 Â°C (281 Â°F) and a melting point of 13.2 Â°C (56 Â°F).It has a specific gravity of 0.86.p-Xylene is flammable and has a flash point of 27Â°C (81 Â°F) or lower.he boiling point of p-xylene is 138.35 Â°C (281 Â°F) and the melting point is 13.2 Â°C (56 Â°F).
