Nylon cable tie fracture analysis
The low temperature resistance of nylon 66 itself is relatively poor, and it is normal for the weather to break in winter. If you want to solve this problem, you can add some raw materials that are resistant to low temperature and have good compatibility with nylon 66. Or replace the long-chain nylon with better low temperature resistance, and solve the problem of nylon 66 cable ties in winter.

Nylon cable tie fracture analysis
Don't think that the finely packed granules are pure materials, many of which are secondary granulation modified products, which will inevitably undergo multiple high-temperature shearing styling.
The molecular structure of the raw material itself has undergone tremendous changes, and the performance has been reduced by more than half, plus degradation and oxidation during the period. Nylon cable ties are guaranteed to be flexible.
Usually nylon has a water absorption during 3-8%. When the molecular structure is destroyed, how to cook it, other water absorption methods will not help, which determines its brittleness, of course, easy to break;

The relationship of the injection molding process is also very important, in order to facilitate the simple and good operation of the molding, by increasing the temperature of the barrel, speeding up the injection molding time, etc.
It will also cause quality problems in the body of the cable tie. The details can be dissected and the cable can be enlarged and observed. Some of them are filled with empty holes, and so on.
Nylon raw materials are all of a variety of types, choose the appropriate flexible system, such as single 6 and so on; the injection molding process must be strictly limited optimization;
Avoid excessive processing damage to raw materials. Overall, it is a meticulous and targeted improvement from raw materials and injection molding processes.

to sum up,
It depends on the specific situation. If it is a small-sized nylon cable ties, it will be easy to break when it is too hard to reach during the use; if it is not easy to break the normal tension, it is the quality of the cable ties itself (some are made with recycled materials, new materials) Generally not); there is also the use of low temperature and relatively dry places, the ordinary cable tie is easy to break (because the cable tie is relatively brittle at this time, the water loss is faster), then you must explain to the manufacturer when purchasing. Use the environment and choose a cable tie with better toughness.
