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.
| MATERIAL | ALTERNATE NAME | LOI | CATEGORY |
|---|---|---|---|
| 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 |
