DuPont™ Formacel® foam expansion agents

DuPont™ Formacel® S
foam expansion agent

DuPont™ Formacel® S (HCFC-22) is a high performing, lower ODP alternative to HCFC-141b commonly used in polyurethane foam systems, insulated metal panels, and doors. It can also be used as a co-blowing agent in extruded polystyrene (XPS) insulation board.

DuPont™ Foramcel® S can be blended with HCFC-141b 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.

Formacel® S (HCFC-22) is among the HCFCs regulated in several countries. Please contact us for availability in your region.
