Just like heat shrink tubing, heat shrink end caps are perfect for situations that call for extra protection against abrasion, moisture, chemicals and corrosion. They’re most commonly used to insulate and seal off wire and splice terminations in automotive, electrical and networking applications. End caps are typically used in conjunction with heat shrink tubing… they take over where the tubing leaves off!
Heat shrink tubing is capable of sealing the entire surface of a cable or wire, but can’t be closed off at the end should that be necessary. That’s where heat shrink end caps come into play: they’re shaped to fit over the ends of wires and cables. Our heat shrink end caps are adhesive lined, so that when one is fitted over the end of a wire, it forms a bond with the heat shrink tubing that it’s overlapping. The seal is completed when heat is applied: the adhesive melts and becomes fully activated, and the end cap material shrinks to a snug and exact fit around the cable’s end.

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 |
