Foam blowing agents are essential ingredients in blown foam insulation, causing the foam to expand while trapping gas that increases its insulating capability. Honeywell has been at forefront of every major improvement in blowing agent technology since their invention in the 1940s. We offer: Enovate® 245fa (HFC-245fa); Solstice® Liquid Blowing Agent (HFO-1233zd(E)); and Solstice® Gas Blowing Agent (HFO-1234ze(E)).

Solstice Liquid Blowing Agent

Solstice LBA has a global warming potential (GWP) of 1, which is 99.9% lower than current HFCs used in the industry. Solstice LBA outperforms alternative blowing agents in foam and environmental performance.

Solstice Gas Blowing Agent

Ideal for extruded polystyrene (XPS) and one- and two-component PUR foams, Solstice GBA replaces HFC-134a and other blowing agents. It has a GWP < 1.

Enovate 245fa Blowing Agent

Enovate 245fa has been the standard in HFC technology for polyurethane foam applications worldwide. It offers proven insulating performance and excellent materials compatibility.
