Global Sulfur Hexafluoride (SF6) Market Size, Trends, and Forecast 2025–2031 | QY Research


 

Global Sulfur Hexafluoride (SF₆) Market

The global Sulfur Hexafluoride (SF6) market was valued at US$ 166 million in 2024 and is anticipated to reach US$ 164 million by 2031, witnessing a CAGR of -0.2% during the forecast period 2025-2031.

The global sulfur hexafluoride (SF₆) market is an essential segment of the specialty chemicals industry, primarily driven by its unique properties such as high dielectric strength, thermal stability, and non-flammability. In 2024, SF₆ remains the preferred insulating and arc-quenching medium in high-voltage electrical equipment like circuit breakers, switchgear, and gas-insulated substations (GIS). Its applications also extend to magnesium production, semiconductor manufacturing, and medical imaging. However, the market faces increasing regulatory scrutiny due to SF₆’s high global warming potential (GWP). This is pushing manufacturers toward developing alternative solutions while ensuring compliance with environmental standards.
