This value places it between the fully fluorinated polymers PTFE, PFA, and FEP with a limiting oxygen index of 95% and other partially fluorinated polymers like PVDF with a limiting oxygen index of 44% or ETFE with a limiting oxygen index of 30%.
This rating places it between the fully fluorinated polymers PTFE, PFA, and FEP, which have a high oxygen index of 95%, and other partially fluorinated polymers like PVDF, which has a lower oxygen index of 44%, or ETFE, with an even lower oxygen index of 30%.
