Abstract

La presente invención se refiere a un proceso para producir una espuma de poliuretano de célula cerrada, caracterizado porque se mezclan al menos 1 por ciento en peso y menos de alrededor de 60 por ciento en peso de un halocarburo que minimiza el encogimiento, seleccionado del grupo que consiste de CFC-11, CFC-12, HCFC-22, HFC-32, CFC-113, CFC-114, HCFC-124, HCFC-133a, HFC-134a, HCFC-142b y HFC-152a y un mínimo de alrededor de 40 por ciento en peso de un halocarburo de dos carbono que contiene hidrógeno seleccionado del grupo que consiste de HCFC-123, HCFC-123a y HCFC-141b, para formar una mezcla y de ahí, utilizar la mezcla para producir una espuma de poliuretano de célula cerrada de minimo encogimiento.
