Thermofix Cable Ties

Thermoflx Cable ties, manufactured from nylon, meet most basic cable tie needs, with choices covering wide range of requirements for size and strength. Thermofix Cable ties One-piece, injection moulded construction provides maximum strength and adjustability for securing all sizes of bundles. Extra features such as rounded edges and bent-tip design make installation easy, fast, accurate and secure. Cable tie installation tools are not required but are suggested where controlled, uniform tension and cut-off applications are desired.

Split mandrel, loop tensile strength tests show that the most vulnerable stress point for a cable tie is its pawl. There is a trade-off between insertion/pull-up ease and strength of a cable tie. The stronger the pawl, the more force is required to insert and pull up the strap as it engages the pawl teeth. Cable ties are designed to optimise insertion ease and still meet or exceed all applicable strength requirements. This magnified cross-section illustrates our full four-tooth locking engagement between strap and pawl under load. This intimate contact between pawl and strap teeth, ensures that the strength of the pawl is fully utilised. Installations under conditions of full tropical sun and/or very low relative humidity, must be referred to THERMOFIX design engineers for evaluation and recommendations. Exterior applications should use black (U.V stabilised) ties.
