Foam blowing agents are an essential ingredient in blown foam insulation, causing the foam to expand while trapping gas in the foam to increase its insulating R-value. We’ve been at the forefront of every major improvement in foam blowing agent technology since their invention in the 1940s. We manufacture and sell three foam blowing agent solutions: Enovate® 245fa (HFC-245fa); Solstice® Liquid Blowing Agent (1233zd(E)); and Solstice® Gas Blowing Agent (1234ze).
Featured Blowing Agent ProductsEnovate 245fa Blowing Agent
A nonflammable, non-ozone-depleting liquid blowing agent, Enovate is the established HFC technology for closed-cell spray foam (ccSPF). CcSPF foam rapidly expands in place, eliminating energy-wasting cracks and gaps found in other insulation materials.Solstice Liquid Blowing Agent
The latest advance in foam blowing agent technology, 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 foam blowing agents in environmental impact, performance, safety and cost.Solstice Gas Blowing Agent
Specifically developed for extruded polystyrene (XPS) and pressurized one- and two-component PUR foams, Solstice GBA is a replacement for HFC-134a and other fluorocarbon and non-fluorocarbon foam blowing agents. It has a GWP of less than 1.
