Solstice Advanced Materials: History and Brand Transition

Our connection to Honeywell

Solstice Advanced Materials was created through the 2025 spin-off of the former Advanced Materials business of Honeywell International Inc.

While now an independent, publicly traded company, Solstice builds on a legacy of more than 100 years of innovation in chemistry and materials science.

We carry forward that heritage — including award-winning Solstice® refrigerants and other specialty technologies — with a dedicated focus on advancing science for smarter outcomes for our customers around the world.
Our history

Solstice Advanced Materials was created through the spin-off of the former Advanced Materials business of Honeywell International Inc., announced on October 8, 2024, and completed on October 30, 2025, making Solstice an independent, publicly traded company.

Solstice Advanced Materials was formerly part of Honeywell’s Energy and Sustainability Solutions business, where it played a critical role in developing next-generation refrigerants, advanced fibres, electronic materials, and pharmaceutical packaging.

Our roots stretch much further back, however: the business dates to the 1800s and became part of Allied Chemical and Dye Corporation in 1920. Allied later evolved into AlliedSignal, which merged with Honeywell in 1999.

Today, we carry forward a long legacy of innovation with a dedicated focus on advancing science for smarter outcomes for our customers around the world.
Why some products still carry the Honeywell name

As part of the separation agreements with Honeywell International Inc., Solstice Advanced Materials acquired a short-term license to use the Honeywell name on select refrigerant product lines.

Over time, as Solstice builds its own brand equity globally, we will transition all offerings fully under the Solstice name.
