Halar® Cable Ties (ECTFE [ethylene-chlorotrifluoroethylene]), have properties similar to Tefzel. The major difference (besides the price) is that Halar resin is rated for use in plenum spaces. This is due to its low smoke density when burned. Its durability is similar to Nylon, and is has excellent impact resistance at normal temperatures as well as at very low temperatures. Halar has good tensile, flexural, and wear-related properties.
Halar is also highly gamma resistant, and is rated for temperatures from -50°C to 150°C. It is also UV resistant and carries a UL 94V-0 flame rating. Basically, if you need good resistance to almost any environment, but low smoke generation (i.e. plenum) is not a concern, go with Tefzel ties, otherwise if you require that all of your components be suitable for plenum (air-handling) spaces, go with Halar ties.
Buyheatshrink.com offers its customers different variations of the Halar cable ties, ranging from different nominal sizes to different minimum loop tensile strength. The shortest nominal size Halar cable tie is the 4” with a maximum bundle diameter of 0.9”. The 4” Halar cable has a minimum loop tensile strength of 18 pounds. The 7” Halar cable ties has a maximum bundle diamtere of 1.9” and the 11” Halar cable tie has a maximum bundle diameter of 3.0”. Both the 7” and 11” Halar cable ties have a minimum loop tensile strength of 50 pounds. Please note that all variations of Halar cable ties come in 100 quantity bags and only in red. Be sure to check out our cable tie tools to help with the cutting off of excess cable tie and to help adjust tensioning.
