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.
