Why some TPU elastic tape is easy to break?

TPU elastic tape is essential components in various garments. It is usually sewed at shoulder part of T-shirt for shaping. And swimwear, underwear, yoga clothes are also have TPU tape inside. But some TPU tape is easy to break when sewing or stretching, which increases the labor cost and time cost of garment production. So instances of breakage can be frustrating for both manufacturers and consumers.

There are two main reasons for the breakage of clear TPU elastic tape. One is the choice of TPU raw material, and another one is the temperature of TPU tape process.

Generally, TPU elastic tape crafted from high-quality TPU raw materials, such as those from renowned brands like BASF, exhibit superior toughness and are less prone to breakage. The choice of quality raw materials significantly influences the overall performance of the elastic band. Conversely, using inferior or recycled materials in the production of TPU elastic tape can lead to inconsistent quality and increased susceptibility to breakage. TPU elastic tape produced from recycled materials, especially those priced between 2-5 USD per kilogram, may demonstrate a higher tendency to break.

Besides raw material, the process temperature is also an important reason. As we know, TPU is a thermoplastic polyurethane with temperature-sensitive properties. To achieve optimal physical characteristics, it needs to be heated to the appropriate temperature during the production process. If the temperature during the production process is too high or too low, it can compromise the integrity of TPU elastic tape, making them more prone to breakage. Precision in temperature control is crucial to ensuring the desired sewing effects.

The susceptibility of TPU elastic tape to breakage is often rooted in the choice of raw materials and the precision of the production process. Manufacturers can mitigate breakage risks by investing in high-quality raw materials and ensuring accurate temperature control during production. Meanwhile, consumers can contribute to product quality by making informed choices and understanding the importance of material selection in the overall performance of TPU elastic tape. Through collaboration between manufacturers and consumers, the industry can work towards minimizing breakage and enhancing the durability of TPU elastic tape.
