Top 10 Companies in the R-515B R-1234ze(E)/R-227ea Azeotrope Low‑GWP Chiller Film Market (2026): Market Leaders Driving Sustainable Cooling

MARKET INSIGHTS

The Global R-515B R-1234ze(E)/R-227ea Azeotrope Low‑GWP Chiller Film market was valued at USD 187.4 million in 2025. The market is forecast to rise from USD 198.6 million in 2026 to USD 342.7 million by 2034, translating into a CAGR of 6.3% over the forecast period.

R-515B is a non‑flammable, low global warming potential (GWP) refrigerant blend formulated as an azeotrope of R‑1234ze(E) and R‑227ea. Designed as a next‑generation alternative to higher‑GWP refrigerants such as R‑134a, R‑515B delivers comparable thermodynamic performance while significantly reducing environmental impact – with a GWP of approximately 299, well below the thresholds targeted under the Kigali Amendment and the European F‑Gas Regulation. In chiller film applications, this refrigerant is increasingly adopted across commercial HVAC systems, industrial process cooling, and data center thermal management infrastructure.

The market is gaining strong momentum spurred by tightening environmental regulations, the accelerating phase‑down of high‑GWP hydrofluorocarbons (HFCs), and growing end‑user demand for energy‑efficient, sustainable cooling solutions. Leading equipment manufacturers have been actively validating and certifying chiller systems compatible with R‑515B, broadening its commercial adoption across key industries. Honeywell and Chemours are among the prominent suppliers advancing the refrigerant’s availability and technical support within the global market.
