A fluid composition includes a poly(alkylene glycol) present in an amount of greater than 85 parts by weight based on the total weight of the fluid composition, and a sterically hindered ester present in an amount of from 0.5 up to 15 parts by weight based on the total weight of the fluid composition. The sterically hindered ester, present in the amount of from 0.5 up to 15 parts by weight based on the total weight of the fluid composition, provides the fluid compositions with excellent fire resistance, without adversely affecting other physical properties of the fluid compositions such as hydrolytic stability. More specifically, the sterically hindered ester has a higher fire point (Fp) than the poly(alkylene glycol), which typically sufficiently lowers the S.F.P. of the fluid composition to allow the fluid composition to rate as a Factory Mutual Approved Fluid.
L'invention porte sur une composition fluide qui comprend un poly(alkylène glycol) présent dans une quantité de plus de 85 parties en poids sur la base du poids total de la composition fluide, et un ester estériquement encombré présent dans une quantité de 0,5 jusqu'à 15 parties en poids sur la base du poids total de la composition fluide. L'ester estériquement encombré, présent dans la quantité de 0,5 jusqu'à 15 parties en poids sur la base du poids total de la composition fluide, dote les compositions fluides d'une excellente résistance au feu, sans affecter de façon défavorable d'autres propriétés physiques des compositions fluides telles que la stabilité hydrolytique. Plus spécifiquement, l'ester estériquement encombré a un point d'incendie (Fp) plus grand que le poly(alkylène glycol), qui typiquement abaisse de façon suffisante le S.F.P. de la composition fluide pour permettre à la composition fluide d'apparaître comme un fluide Factory Mutual Approved Fluid.
