Gases for electronic industry-Sulphur hexafluoride(SF6)
[Appearance]：Sulfur hexafluoride SF6 is gaseous substance under normal conditions,and it will bi high-pressure liquid in steel cylinder,SF6 is colorless,odorless,nontoxic,nonflammable and noncorrosive.
[Property]：SF6 has excellent chemical stability and thermal stability,good electric insulation porperty and excellent arc extinguishing property.
[Applications]：SF6 is mainly used in power industries,metallurgy industries,meteorology industries and so on.At present,SF6 is widely used in circuit breaker,electric allocating system,transformer,arrester,capacitor,mutual inductor,particle accelerator,tracer for atmospheric diffusion testing,refrigerants,Anti-oxidants for smelting Mg,Al and relevant alloy. It also can be used as etchant is semiconductor industry,as fiber separation layer dopant in the process of manufacturing optical fiber, it is also a kind of important laser material in the application of laser. Now,the product of SF6 has also been used in the field of aviation,spaceflight ad medical treatment.
[Packing]：Sulfur hexafluoride is normally filled in 40L\8L steel cylinder.
[Storage and transportation]：Handle with care,collision is forbidden.keep off the sunlight and moisture and keep ventilation.keep it away from heat and greasy dirt.
