Product Description

Sulfur Hexafluoride (SF6) technical grade 99.995% 99.999%

Sulphur hexafluoride (SF6) is a colorless, odorless, odorless, non-toxic non-combustible gas with a molecular weight of 146.06 and a density of 6.139 g/l, approximately 5 times that of air. It is one of the best materials with known chemical stability, and its inertness is similar to that of nitrogen. It has excellent thermal stability and does not decompose even at temperatures above 500°C in pure form.
SF6 has excellent electrical insulation and arc extinguishing properties. Under the same conditions, its insulation capacity is 2.5 times more than that of air and nitrogen, and its arc extinguishing capacity is 100 times that of air. The melting point of sulfur hexafluoride is -50.8°C, which can be used as a special refrigerant in the temperature range of -45-0°C, and because of its good heat resistance, it is a stable high-temperature heat carrier. Sulfur hexafluoride has been widely used in power, electronics, and electrical industries and laser, medical, meteorology, refrigeration, firefighting, chemical, military, aerospace, nonferrous metallurgy, and physics research due to these and other excellent features.

FAQ

1. Are you a manufacturer?

No. However, we are sole distributor for our manufacturer. So there is no doubt that we can offer our customers the best prices.

2. What is your MOQ?

We can quote based on our customers' quantity. However, DG cargo should be exported in one container, so we suggest that the quantity should be one container or more. Price will be less if the quantity is more.

3. How about your lead time of production?

Normally, it is 25-30 days after PO and deposit by T/T

4. Can we get the COA and MSDS of the gases we need?

Sure. COA and MSDS are available.

5. Can we send the gas cylinders back and let you refill if they are reusable?

Yes. But you need to inform us in advance, because we need to handle the import customs clearance before exporting.
