Understanding the Heat Resistance Characteristics of Nylon Zip Ties.

If you are using zip ties for a project, then you owe it to yourself to understand the characteristics of the different polyamides that give the zip ties their resistance to heat. Ever since they were introduced commercially in 1938, nylon zip ties were hailed for their incredible balance of properties, combining flexibility with stiffness, a low coefficient of friction and resistance to abrasion.

Below are some specific applications for zip ties as relates to their heat resistance.

General-Purpose Nylon 6/6

This is the grade that is most often used for general purpose zip ties. General-purpose nylon has a working temperature range of 40°F to 185°F. The temperature that is suitable for most continuous applications maxes out at 150°F. General-purpose nylon meets UL 94V – 2 flammability ratings.

In order to get the best performance, you should be sure to use nylon 6/6 zip ties. This is the type of zip tie with both physical and chemical certification for use when in the presence of oxidizing agents, strong acids and even phenols. This type of nylon is resistant to chemicals and most fuels as well as lubricants.

Heat Stabilized Nylon 6/6

Heat stabilized nylon is a zip tie that is suitable for applications that will involve continuous exposure to temperatures higher than 150°F. Most heat stabilized nylon is suitable for temperatures up to 250°F. This means that heat stabilized nylon meets UL standards for all electrical applications.

UV Stabilized Nylon 6/6

UV stabilized nylon is best used when applications will be exposed to outdoor elements on a continuous basis. Aside from being heat resistant, UV stabilized nylon zip ties is also weather resistant with the ability to endure UV light.
