Materials | Free Full-Text | Thermal Decomposition Properties

In pure SF 6, SF 6 begins to decompose at about 260 °C, and reaction between SF 6 and epoxy resin would help add to the whole weight of the residue. The decrease of SF 6 content in gas mixture will reduce the thermal stability of the system, making epoxy resin easier to react with SF 6. 3.2.
