The present invention provides a method for providing an anhydrous poly(alkylene glycol)-based fluid composition with Group 1 or Group 2 fire resistance properties. According to the method, the fluid composition is formulated with an ethylene oxide/alkylene oxide wt. percent ratio and/or an amount of antioxidant sufficient to provide the fluid composition with a spray flammability parameter of less than 8.0 x 104. Fluid compositions formulated according to the invention are useful as hydraulic fluids and quenchants and in other industrial and commercial applications requiring fluids having enhanced fire resistance.
La présente invention concerne un procédé pour l'obtention d'une composition fluide à base de poly(alkylène-glycol) présentant les propriétés de résistance au feu du groupe 1 et du groupe 2. Selon ce procédé, la composition fluide est formulée avec rapport en pourcentage de masse entre oxyde d'éthylène et oxyde d'alkylène et/ou une quantité d'antioxydant qui suffisent pour maintenir le coefficient d'inflammabilité en pulvérisation en dessous de 8,0 x 10?4¿. Ces compositions conviennent pour des fluides hydrauliques et des fluides d'extinction, ainsi que pour d'autres applications industrielles et commerciales nécessitant des fluides à résistance au feu renforcée.
