Everything You Need to Know About SF6 Gas: A Comprehensive Guide
Time : 2025-03-20

What is Sulfur Hexafluoride (SF6) Gas?


Sulfur hexafluoride (SF6) is a synthetic, inert, non-toxic gas composed of sulfur and six fluorine atoms. Known for its exceptional dielectric strength and thermal stability, SF6 is widely used in high-voltage electrical equipment, medical applications, and industrial processes.


What Are the Key Technical Parameters of SF6 Gas?

  • Chemical Formula: SF6

  • Purity: ≥99.99% (industrial-grade) | ≥99.999% (ultra-high purity for medical/electronics)

  • Density: 6.17 kg/m³ (at 20°C)

  • Dielectric Strength: 2.5x higher than air

  • Global Warming Potential (GWP): 23,500x CO2 (requires responsible handling)


What Are the Physical Properties of SF6 Gas?

  • State: Colorless, odorless, non-flammable gas

  • Boiling Point: -64°C (-83°F)

  • Stability: Chemically inert under standard conditions

  • Thermal Conductivity: Low, ideal for insulation


What Are the Primary Uses of SF6 Gas?

  • Electrical Industry: Insulation and arc quenching in circuit breakers, transformers, and switchgear.

  • Medical: Contrast agent in ultrasound imaging.

  • Manufacturing: Etching agent in semiconductor production and magnesium processing.

  • Scientific: Tracer gas for atmospheric studies.


How Should SF6 Gas Be Stored and Transported Safely?

  • Storage: Keep cylinders upright in cool, ventilated areas (<50°C). Avoid direct sunlight.

  • Transportation: Secure cylinders with caps and use ISO-certified containers. Comply with local pressure vessel regulations.

  • Safety: Use leak detectors; SF6 is heavier than air and can displace oxygen in confined spaces.


What Are the International Shipping Requirements for SF6 Gas?

  • IMO Compliance: Classified as a non-flammable, non-toxic gas (UN 1080). Requires Class 2.2 hazard labels.

  • Documentation: SDS, shipping manifests, and customs declarations must specify SF6 content.

  • Packaging: DOT/ISO-approved steel cylinders with pressure relief devices.

  • Environmental Regulations: Track and report emissions under the Kyoto Protocol (for EU/UN shipments).
