As the tpu film manufacturer is composed of an elastomer, it must undergo a drying and dehumidifying process before being mixed and matured by the screw and extruded through the die. Unfortunately, any instability with the raw materials used can result in uneven film thickness. Therefore, it is essential to carefully monitor and control all factors involved in the manufacturing process to ensure consistent film quality.
For smaller and medium-sized TPU film manufacturers, managing the thickness of their films and minimizing scrap rate can be challenging due to the high cost of advanced testing equipment. These manufacturers often struggle with controlling the quality of their products without access to expensive machinery.
Conventional TPU is generally said to be heat resistant to 80°C, which means that its long-term use temperature cannot exceed 80°C, otherwise the service life will be severely reduced. There are also heat-resistant TPUs, which are said to be able to withstand up to 130°C, and there are also TPUs modified with glass fiber, which have a high heat-resistant temperature.
The production of protective clothing is reliant on TPU film as a significant raw material. A single piece of protective clothing necessitates around 4 square meters of this film. Our priority is to resume work and manufacture anti-epidemic materials for downstream medical establishments. According to Leng Yong, the Chief Engineer of Zhongshan Borius, TPU film has excellent barrier properties and is impervious to bacteria and viruses. The film is non-porous, and water molecules can move between molecules without letting harmful microorganisms penetrate. This quality makes TPU film very useful for protective clothing, medical supplies, and other healthcare-related products.
