Plastic zip ties degrade in sunlight
Plastic zip ties can be extremely strong, with some heavy-duty zip ties offering a tensile strength of up to 250 pounds. However, their strength and durability are affected by various factors, including exposure to sunlight and environmental conditions.
When used outdoors, plastic zip ties are susceptible to UV degradation. UV rays from the sun can break down the molecular structure of the nylon over time, causing the zip ties to become brittle and weak. This process can occur in a couple of years, or even months if the ties are exposed to direct sunlight. Therefore, it is crucial to consider the environment in which the zip ties will be used and opt for high-quality, UV-resistant zip ties to prolong their lifespan.
UV-resistant zip ties are specifically designed to withstand the harmful effects of sunlight. They are formulated with additives that protect them from UV degradation, ensuring their durability even in harsh weather conditions. These zip ties are an excellent choice for outdoor applications, as they can endure exposure to extreme heat, cold, and moisture without accelerated degradation.
The longevity of plastic zip ties in outdoor settings depends on several factors. In addition to exposure to sunlight, the material of the zip ties and the environmental conditions can impact their durability. For example, extreme heat or cold can accelerate the degradation process, causing the zip ties to deteriorate faster. Therefore, it is essential to choose zip ties that are suitable for the specific environmental challenges of your project.
Overall, while plastic zip ties can be strong and durable, they are susceptible to degradation in sunlight. To ensure the longevity of your project, it is crucial to select UV-resistant zip ties and consider the environmental factors that may affect their performance.

Metal zip ties are stronger than plastic
Plastic zip ties are convenient and low-cost, but they have some disadvantages. For instance, they have low tensile strength and are susceptible to UV degradation, which causes them to deteriorate quickly. They are also not suitable for use in places that require high tensile strength, such as in extremely low or high-temperature environments.
Metal zip ties, on the other hand, are made of metal and therefore do not degrade in the environment. They are ideal for rugged applications that require high heat resistance, such as strapping insulation wrap over exhaust pipes. Metal zip ties also have a higher tensile strength than plastic zip ties, with a tensile strength of over 1.5 tons.
The higher tensile strength of metal zip ties makes them suitable for use in places where high tensile strength is required. For example, stainless steel zip ties can be used outdoors for more than ten years and have good corrosion resistance and oxidation resistance.
Additionally, metal zip ties are less susceptible to environmental factors such as cold weather, which can cause plastic zip ties to crack. Metal zip ties are also more difficult to break by hand, making them more secure than plastic zip ties.
In summary, while plastic zip ties are convenient and inexpensive, metal zip ties offer superior strength, durability, and resistance to environmental factors. They are ideal for applications that require high tensile strength, heat resistance, and longevity.

Zip tie strength is measured in LTS
Zip ties, also known as cable ties, come in a variety of strengths, thicknesses, and materials. The strength of zip ties is measured in loop tensile strength (LTS), which is the amount of weight that can be applied to a zip tie's locking mechanism once it has been fastened. The LTS of a zip tie is determined through a standardised testing process. During testing, the zip tie is closed and tightened onto a machine, which then slowly applies force to pull the zip tie apart until it breaks. The amount of force required to break the zip tie is recorded, and this weight limit is listed by most manufacturers on the packaging of the zip tie.
There are five primary ranges of zip tie strength, categorised based on their LTS values. These categories include standard, intermediate, heavy duty, and extra heavy duty. The specific LTS values for each category may vary depending on the manufacturer and the material of the zip tie. For example, automotive zip ties typically have an LTS range of 18 to 250 pounds, while nylon zip ties can have an LTS of up to 175 pounds.
The strength of a zip tie is crucial in determining its suitability for different applications. Heavy-duty zip ties, for instance, are designed for jobs that require more strength and durability. Stainless steel zip ties are often used in construction work and automotive repair due to their high LTS values, which can range from 200 to 350 pounds or even higher. Additionally, stainless steel zip ties are resistant to extreme temperatures, vibration, and radiation, making them suitable for outdoor use.
The method used to break a zip tie also plays a role in its overall strength. While it may be possible to pick the locking mechanism of a zip tie, snapping it by force requires significant effort, especially for heavy-duty varieties. Furthermore, certain geometries can magnify the forces applied to a zip tie, such as when the load is hanging in the centre of a horizontal section of the tie. This can lead to uneven weight distribution, causing one zip tie to bear more load than the others and eventually break.
In summary, the strength of zip ties is measured in LTS, and this value is determined through standardised testing procedures. The LTS of a zip tie dictates its categorisation and suitability for various applications. Factors such as material, thickness, and geometry can influence the overall strength of a zip tie, making it crucial to select the appropriate type for the intended purpose.
