Why are nylon zip ties prone to breakage
Analysis of Nylon Cable Tie Fracture Part 1
Nylon cable ties themselves have poor low temperature resistance, and it is normal for them to break in cold winter weather. If you want to solve this problem, you can add some materials that are resistant to low temperatures and have good compatibility with nylon cable ties. Or replace it with a longer carbon chain nylon with better low-temperature resistance. We have materials to solve the problem of nylon cable ties breaking in winter
Analysis of Nylon Cable Tie Fracture II
Don't think that the beautifully packaged particles are pure materials. Many of them are modified products through secondary granulation, which will inevitably undergo multiple high-temperature shearing and shaping processes. The molecular structure of the raw materials themselves has undergone significant changes, and their performance has been reduced by half, coupled with degradation, oxidation, and other factors during this period. Nylon zip ties need to ensure their flexibility. Usually, nylon has a water absorption rate of 3-8%. When the molecular structure is damaged, no matter how much cooking is done, other water absorption methods are useless, which determines its brittleness and easy breakage;

The relationship between injection molding process is also very important. In order to facilitate and simplify the operation of molding, increasing the temperature of the material cylinder, accelerating the injection molding time, and so on, can also cause quality problems with the cable tie body. Details can be dissected and observed by enlarging the cable tie, and some of the interiors are filled with unfilled holes, and so on. Nylon raw materials themselves come in many types, so choose the appropriate flexible series, such as single 6, to be used in combination; The injection molding process must be strictly limited and optimized; Avoid excessive processing damage to raw materials. Overall, it means starting with detailed and targeted improvements in raw materials and injection molding processes.
summarize
It 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 is easy to break without reaching normal tension, it is because there is a quality problem with the zip ties themselves (some are made from recycled materials, while new materials generally do not); Also, when used in low temperature and relatively dry places, ordinary cable ties are prone to breakage (because they are more brittle and lose moisture quickly). When purchasing, it is necessary to explain the usage environment to the manufacturer and choose cable ties with better toughness.
