As a professional manufacturer and exporter of specialty gases, we supply SF₆ gas with industrial grade (99.995%) and electronic grade (99.999%). Produced with advanced purification technology and strictly tested per GB/ISO/DOT standards, our SF₆ features high chemical stability, ultra-high dielectric strength and strong arc-quenching capability. It is widely used in power systems, semiconductor manufacturing, metallurgical protection and other high-end industries. With standardized cylinder packaging and complete export qualifications, we provide stable supply and professional technical support for global customers.

Key Product Specifications

Purity Grade & Impurity Control

We provide gradient purity SF₆ gas with strict impurity control, ensuring stable performance for different application scenarios:

All batches are inspected by advanced analytical instruments, with third-party test reports available to verify purity and impurity levels.

Physical & Chemical Properties

Sulfur Hexafluoride is a chemically stable inert gas with unique physical and chemical characteristics:

• Electrical Insulation: Dielectric strength is 2.5 times that of air, arc-extinguishing capacity is 100 times that of air, ideal for high-voltage electrical equipment.

• Stability: Stable at room temperature, does not react with metals (Cu, Ag, Fe, Al) below 300℃; does not react with quartz below 500℃.

• Solubility: Slightly soluble in water, soluble in ethanol, ether and other organic solvents.

• Safety Notes: Non-flammable and non-toxic, but has asphyxiant effect at high concentrations; storage and use require well-ventilated environment, avoid high temperature and pressure.

Packaging & Shipping

We provide GB/ISO/DOT compliant packaging solutions for global markets, supporting small-batch trial orders and large-volume bulk supply:

• Standard Cylinders: 40L/47L/440L steel cylinders with corrosion-resistant 316L stainless steel G5/8 or CGA580 valves, ensuring airtightness and safe transportation.

• Bulk Supply: ISO tanks for large-scale industrial applications, complying with international dangerous goods transportation standards.

• Compliance: All packages meet UN 1080 regulations; complete SDS safety data sheets, batch purity certificates and export qualification documents are provided for smooth customs clearance.

Main Applications

Sulfur Hexafluoride is an irreplaceable specialty gas in power, semiconductor and metallurgical industries:

1. Power Industry: Core insulating and arc-extinguishing medium for GIS (Gas Insulated Switchgear), high-voltage circuit breakers, transformers, current/voltage transformers and arresters.

2. Semiconductor Industry: High-purity SF₆ is used for silicon wafer etching, ion implantation and electronic component encapsulation protection, ensuring precision processing.

3. Metallurgical Industry: Protective gas for magnesium and aluminum alloy smelting, preventing oxidation and improving casting quality.

4. Other Fields: Tracer gas for meteorological and environmental monitoring, refrigerant for refrigeration industry, and shielding gas for particle accelerators.
