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|
|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|
|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|
