Solstice to Sample Next-Generation Non-PFAS Foam Blowing Agent in Early 2027

Solstice Advanced Materials has reached a development milestone for a next-generation foam blowing agent and plans to begin sampling the candidate with selected global customers in early 2027. The technology is intended for insulating foams used in building insulation, appliances, insulated panels, and other rigid foam products.

Environmental and technical profile

According to Solstice's internal evaluation, the developmental candidate would not be classified as per- and polyfluoroalkyl substances (PFAS). The company also states that the agent would not form trifluoroacetic acid (TFA) in the atmosphere or contribute to its environmental accumulation. The candidate is designed to provide thermal performance, nonflammability, low global warming potential, and approximately zero ozone depletion potential.

Jeff Dormo, Senior Vice President, Refrigerants and Applied Solutions at Solstice, noted that customers have shown strong interest in foam blowing agent solutions that would not be classified as PFAS while retaining other important characteristics, and that this developmental candidate reflects the company's commitment to innovation in support of its customers' needs.

Sampling program and target applications

During the sampling program, Solstice will work with selected customers to evaluate formulation compatibility, processing behavior, and application-specific requirements. Target applications include:

• Spray polyurethane foam
• Appliance insulation
• Insulated panels
• Boardstock
• Other rigid foam products

Solstice will continue supporting its existing foam blowing agent portfolio while the new candidate is under development.

Existing portfolio performance

According to the company, its existing technologies have demonstrated potential insulation performance improvements of up to 25% in polyisocyanurate boardstock and 56% in spray polyurethane foam systems compared with certain conventional blowing agents. In appliance insulation, Solstice technologies have demonstrated potential refrigerator energy consumption reductions of up to 10% compared with hydrocarbon-based blowing agents.
