What's special about this heat shrink tubing?

  • Has a high viscosity hot melt adhesive that flows through gaps in bundles for a secure and weatherproof connection
  • High flowing adhesive provides superior strain relief for bundled cables
  • Clear tubing has color dashes on it to easily identify the size of the heatshrink using standard AWG colors

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
