Why are nylon cable ties easy to break- Jijin Industral Co., Ltd.

1. The low temperature resistance of nylon 66 itself is relatively poor, and it is normal for it to break when the weather is cold in winter. If you want to solve this problem, you can add some raw materials with low temperature resistance and good compatibility with nylon 66. Or replace the long carbon chain nylon with better low temperature resistance. We have materials to solve the winter breakage of nylon 66 cable ties

2. Do not think that the finely packaged granules are pure raw materials, many of which are modified products of secondary granulation, and will inevitably undergo multiple high-temperature shearing modeling. The molecular structure of the raw materials itself has undergone great changes, and the performance has been reduced by most degradation, oxidation, etc. Nylon cable ties must ensure its flexibility. Usually nylon has a water absorption rate of 3-8%. When the molecular structure is destroyed, no matter how to cook, other water absorption methods will not help, which determines its brittleness. Of course, it is easy to break ;

3. The relationship between the injection molding process is also very important. For the convenience of molding and simple operation, by increasing the temperature of the barrel, speeding up the injection time of injection molding, etc., there will also be quality problems in the body of the cable tie. The details can be dissected and enlarged to observe , some are filled with unsatisfactory voids, and so on. There are many types of nylon raw materials themselves. Choose the appropriate flexible system, such as single 6, etc. to be used together; the injection molding process must be strictly limited and optimized; to avoid excessive processing damage to the raw materials. Generally speaking, it is a meticulous and targeted improvement from the raw materials and injection molding process.

Summarize

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