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.
POLYFOAM Polyurethane(PUR)/Polyisocyanurate(PIR) can be easily cut with saw blades or knives. it is resistant to all kinds of adhesives, biturninous emulsions and hot bitumen (180c to 220 c). We will, however assist you to find the proper adhesives for your particular application. Fire performance-POLYFOAM PUR/PIR is usually used at lower thicknesses than other insulants, so that their heat or fuel contribution to a fire is low compared to other thicker insulating materials. 2  Enhanced compressive and tensile strength at cryogenic temperatures make it resistant cracking.
