The Limiting Oxygen Index (LOI) is a measure of the ratio of Oxygen to other gases in the air surrounding a substrate. Normal atmospheric air (i.e. the air we breathe) is approximately 21% Oxygen, so a material with an LOI of less than 21% would burn easily in air. That being said, a material with LOI of greater than 21% but less than 28% would be considered "slow burning". A material with LOI of greater than 28% would be considered "self-extinguising". A self-extinguishing material is one that would stop burning after the removal of the fire or ignition source.Here are some typical values for LOI of some popular plastic materialsPolyethylene, Polypropylene: 17.4%PET: 21-34%Nylon 6,6: 24-29%Polyvinyl Chloride (PVC): 45-49%Halar (E-CTFE): 64%Teflon (PTFE): 95%Nomex: 28%.
