DuPont HCFC-141b is an alternative to CFC-11 in polyurethane foam systems.
DuPont HCFC-141b can be blended with Formacel® S as a co-expansion agent. Foams produced with this blend exhibit lower cost, superior dimensional stability, and improved insulation value at low temperatures than similar foams made with HCFC-141b alone.
HCFC-141b is among the HCFCs regulated in several countries. Please contact us for availability in your region.
