What are nylon cables ties? What are they made from and what can I use nylon cable ties for? And exactly how strong are they? We have the answers to all your questions in this helpful guide.
A nylon cable tie is a long thin strip of nylon that is used to hold items, usually cables, together in bundles. Cable ties were originally invented by Maurus C Logan after a visit to an aircraft facility in the s. He witnessed the devastating effects that securing the aircraft cabling and wiring had on workers&#; hands, and decided to create something to make their lives easier. It took him 2 years to finalise the design, which was patented in . Cable ties are also known as zip ties, hose ties or Ty-Rap (a brand name).
One end of a cable tie is pointed and features serrations or ridges (a gear rack). The opposite end of the tie has a ratchet within a square hole. When the pointed end is passed through the square head and past the ratchet, it cannot be pulled back, resulting in a loop which can be tightened and which self-locks.
Nylon cable ties are made from a group of plastics known as polyamides and are usually either nylon 6 or nylon 6/6. These figures refer to the chemical structure of the particular nylon used and while each type shares some qualities, we supply only nylon 6/6 cable ties. To learn more about the science behind the types of nylon used in the manufacture of cable ties, read our blog What are cable ties made of?
Still predominantly used to bundle wiring and cables together, cable ties today play a part in industrial, commercial and domestic applications. In the aircraft and automotive industries, cable ties enable efficient cable management and the range of sizes available allows them to be used for everything from large, heavy hoses to delicate wiring in confined spaces. Their chemical and heat resistant properties also makes them ideal in environments where oil and petrol are to be found. In food production and the pharmaceutical and healthcare industry, variations of the standard nylon 6/6 cable tie are used. Closer to home, cable ties are indispensable for keeping unruly and unsightly cables at bay in the home office or behind the entertainment station. However, they can also be used in the garden and elsewhere around the house and some people have been known to create works of art out of them!
Cable tie strength is known as tensile strength and is generally measured and given in kilograms. For example, our 80mm x 2.5mm nylon 6/6 cable tie has a tensile strength of 8kg which refers to the maximum load this cable tie can bear before breaking. Our widest nylon 6/6 cable tie (12.7mm) has a tensile strength of 114kg. Our blog, How strong are cable ties? discusses the tensile strength of all our cable ties.
Nylon 6/6 cable ties are strong and flexible and offer a high resistance to heat and chemicals. With a working temperature range of minus 40°C to 85°C (minus 40°F to 185°F), nylon 6/6 meets all UL94V-2 flammability ratings. Nylon 6/6 can also be heat stabilised without compromising its physical properties when exposed to temperatures up to 125°C, and it can also be UV stabilised making it ideal for prolonged outdoor exposure.
In addition to our standard nylon 6/6 cable ties, we offer printed nylon cable ties, releasable cable ties, marker cable ties, metal detectable nylon cable ties, and UV & heat stabilised cable ties. So, whatever the job you are tackling, we are sure to have a cable tie to meet your needs.

10 May 12 14:39I've got an application where I need to install cable ties to support a submersed product . the product weighs about 5.0lbs and will be strapped on a 2" pipe.. I know nylon is hygroscopic, but I've done some testing under hot water for about five weeks with positive results but I'm worried about long term. Given that it's not supporting much weight, does anybody know if it ok. to use Nylon cable ties for this situation?

10 May 12 14:44Nylon 12 ties would be a better option (if you can get them where you are in the world)
Nylon 6 and 6.6. do not like chlorides much so avoid salt water, etc.

Why be happy when you can be normal?

10 May 12 18:31A lot of nylon rope is used on ships. It is mostly nylons 6 or 6.6. Also many fittings on sailing boats are nylons 6 and 6.6.
Chlorides are certainly an issue in the presence of zinc such as contained in poor quality brass.
I am more concerned about the temperature of the hot water.
Nylon will soften and lose tensile strength with exposure to water due to it being hygroscopic, but it will reach equilibrium with the water and stabilise. As nylon is quite strong even after water absorption, it will depend on the load. To test place a cable tie in hot water (say 80 deg C for say a week, then test strength. By then it will have absorbed all the water it is likely to.
A second issue however is relevant. You mention temperature. Nylons also hydrolyse in hot water given time.

11 May 12 09:12Thanks for the feedback.. My test was done with 70°C Water for three weeks. I'm pretty sure it reached maximum water absorption. Although the cable ties (which are Nylon 6/6) became brittle, they easily maintained the necessary strength. The product will not be exposed to those temps very frequently. (about as frequent as you will purge a boiler). However, it will frequently be exposed to brine water. What sort of problems do Chlorides present? will the Nylon react to chlorides and decompose?

11 May 12 09:46At 70 deg C it will.

25 May 12 06:31How about looking at the rapstrap?Not sure if it will be strong enough though. Made from elasticated polyurethane

25 May 12 07:57Polyurethanes can be quite poor to hydrolysis in water at room temperature. 70deg C sure as hell won't reduce that problem.
