Our product line includes:


Low GWP Products

  • Opteon™ 1100 (HFO-1336mzz-Z) – Formacel™ 1100, the low global warming potential (GWP) foam blowing agent that combines energy efficiency with extended shelf life, has a new name: Opteon™ 1100. Opteon™ 1100 is the newest addition to the Opteon™ family of low GWP fluorochemicals and the portfolio of foam blowing agents from Chemours. It boasts the lowest GMP and can serve as an HCFC-141b alternative with minimal modifications.
  • Formacel™ Z2 (HFC-152a) – The non-VOC and low-GWP formulation make it an ideal – and approved – foam blowing agent in the food service, house wrap and graphic arts industries.


Low ODP Products

  • Formacel™ Z4 (HFC-134a) – The nonflammable compound delivers superior insulation and excellent plastic liner compatibility, making it a perfect fit for roofing, pipe insulation, appliance foams, refrigerated trucks and much more.
  • Formacel™ S (HCFC-22) – A high-performing alternative to HCFC-141b used as a co-blowing agent in insulation board, refrigerated trucks, food services, graphic arts and house wrap. Because HCFC regulations vary by country, please contact us for availability in your region.


Legacy Product

  • HCFC-141b – An alternative to CFC-11 in polyurethane foam systems. Blending HCFC-141b with Formacel™ S as a co-expansion agent can reduce costs, while driving stability and low temperature insulation value. However, HCFC regulations vary by country; please contact us for availability in your region.

We also offer a wide range of HFC, HCFC and HFO blends to meet your company’s unique needs.  Contact our sales team to learn more.


This new performance-based alternative leverages hydrofluoroolefin (HFO) chemistry to achieve peak physical properties capable of replacing legacy HCFCs, HFCs, and HCs.
