Production and processing techniques of TPU elastic tape

TPU (Thermoplastic Polyurethane) has emerged as the material of choice in the production of elastic tape, celebrated for its remarkable durability and flexibility. TPU elastic tape is widely used for garment, which is clear, invisible and elastic. By the way, TPU tape is also named mobilon tape. However, unlike traditional elastic materials, the production and processing of TPU require a series of advanced techniques. This article delves into the methods involved in the production and processing of TPU tape.

1. Material Selection:

The primary component of TPU is polyurethane, which is synthesized from polyols, isocyanates, and chain extenders through chemical reactions. These raw materials need to be mixed and heated under stringent conditions to ensure high-quality TPU.

2. Extrusion:

Extrusion is a common method for manufacturing TPU tape. The raw material is placed into an extruder. Under high temperatures and pressures, it's pushed through a mold to achieve the desired shape. This process ensures the continuity and uniformity of the tape.

3. Injection Molding:

Another prevalent method of TPU processing is injection molding. This involves injecting molten TPU into a pre-designed mold, followed by rapid cooling to solidify it into the desired shape.

4. Hot Pressing:

For specific applications, like clear elastic tape requiring unique textures or patterns, hot pressing might be the method of choice. Here, TPU is placed between two heated metal plates and pressed into the desired shape at elevated temperatures.

5. Post-Processing:

The produced TPU tape might require some post-processing, such as trimming, edging, printing, or coating, to meet specific application requirements.

6. Environmental Friendliness:

Compared to many other plastics, TPU is a relatively eco-friendly material. It doesn't contain harmful substances and is biodegradable. Nevertheless, to further reduce environmental impact, many manufacturers are exploring methods of using renewable resources as raw materials.

In conclusion, the production and processing of TPU elastic tape can be relatively intricate, involving various techniques and methods. With technological advancements, we can anticipate further innovations and improvements, enhancing both the performance and eco-friendliness of TPU tape.

Producing high-quality mobilon tape necessitates precise craftsmanship, top-tier raw materials, and cutting-edge equipment. Only in this way can the bands produced meet the ever-growing market demands, ensuring their longevity and reliability in various applications.
