Expando FR Plus contains a patented fray resistant treatment.
Self Extinguishing - 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.
Expando FR with the patented Bentley Harris fray-resistant Plus treatment. Perfect for when you need flame retardant PET expandable braided sleeving with a fray resistant end. UL VW-1 and FAR Part 25 flame rated.
