    Limiting Oxygen Index (LOI)

    The ratio of how much oxygen - as compared to other gases - needs to be present in the air surrounding a particular material in order for that material to burn. The fact that Earth's normal atmospheric air contains around 21% oxygen is used a reference point when materials are classified into burn categories that are based on Limiting Oxygen Index. Substances that are combustible in air containing less than 21% oxygen are considered flammable, while those that burn in the range of anything greater than 21% but less than 28% are typically labeled "slow burning". Any material with an LOI that exceeds 28% is classified as self-extinguishing.

    In the table below, you'll find a list of polymers commonly found in our heat shrink tubing and braided sleeving products, along with their LOIs and the burn categories each falls into.

    ECTFE (Ethylene chlorotrifluoroethylene) Halar 64% Self Extinguishing
    Nomex N/A 28% Slow Burning
    Nylon 6:6 N/A Ranges fron 24-29% Slow Burning to Self Extinguishing
    PET (Polyethylene Terephthalate) Mylar (film), Dacron (fiber) Ranges from 21-34% Slow Burning to Self Extinguishing
    Polyethylene (PE) N/A 17% Flammable
    Polypropylene (PP) polythene (in the UK) 17% Flammable
    Polytetrafluoroethylene (PTFE) Teflon 95% Self Extinguishing
    Polyvinyl Chloride (PVC) N/A Ranges from 45-49% Self Extinguishing
