Solstice to trial non-PFAS blowing agent
14th November 2026
USA: Solstice claims to have reached a key milestone for a next-generation foam blowing agent and plans to begin customer trials in early 2027.
According to Solstice, the proposed new foam blowing agent addresses customer requirements with regard to thermal performance, non-flammability, low global warming potential and “approximately zero” ozone depletion potential. It also claims that the blowing agent would not be classified as a PFAS substance under current US EPA and OECD definitions and would not form TFA,
Although Solstice has not revealed the identity or composition of this new blowing agent, its “approximately zero” ODP suggests it may be, or may contain, a hydrochlorofluoro-olefin (HCFO). HCFOs, such as HCFO1233zd(E) – which Solstice uses as its current Liquid Blowing Agent (LBA) – do contain chlorine and can possess a negligible or very low ODP.
“This next-generation foam blowing agent candidate builds on Solstice’s longstanding history of developing advanced technologies for the foam industry,”
“Customers have been very interested in foam blowing agent solutions that would not be classified as PFAS while retaining other important characteristics, and this developmental candidate reflects our commitment to innovation in support of our customers’ needs,” said Jeff Dormo, Solstice’s senior vice president, refrigerants and applied solutions.
