With the in depth research and development of TPU film products and the improvement of the technical level of TPU film industry

    The application range of TPU film is gradually extending from the original key fields such as shoes, clothing, home textiles, and luxury handbags to new fields such as agriculture, medical care, electronics, aerospace, and military industry.

    In addition, TPU film is easy to recycle and biodegrade. With the alternate development of industrial technology, it has become a trend worldwide to replace non-environmentally friendly films with TPU films.

    In the future, with the in-depth research and development of TPU film products and the improvement of the technical level of the TPU film industry, the application field of TPU film will continue to expand

    The scope of application of TPU film is constantly expanding, extending from the previous key fields such as shoes, clothing, home textiles and luxury goods to emerging fields such as agriculture, medical treatment, electronics, aerospace and military industry. At the same time, TPU film is a new type of industrial material that can be sustainably modified. By adjusting raw materials, formulas and production processes, its performance can be further optimized and its application range can be expanded, thus endowing TPU film with stronger vitality and durability.

    However, like good and bad, even the most perfect product has shortcomings. The high temperature resistance, chemical corrosion resistance and dependence on raw material imports of TPU film have become three aspects that need attention

    The first is the chemical resistance of the TPU film. It is not resistant to strong polar solvents and strong acid-base media. Alcohols, acids and ketones will cause its elastomers to dissolve and degrade. At room temperature, solvents such as dichloromethane and trichlorethylene can also cause the swelling reaction of TPU.

    The second is the high temperature resistance of the TPU film. Although the material has good elasticity and toughness at low temperatures, it is difficult to withstand high temperature environments. TPU has a large internal heat, and it is easy to lose elasticity and toughness in a high temperature environment. The normal operating temperature range is -30°C to 80°C, so it is not recommended to use TPU film above 120°C for a long time.

    The third point to note is that for the domestic TPU film industry, its dependence on foreign countries is high, and the import of TPU raw materials is relatively high, which also brings certain risks and challenges.

TPU hot melt adhesive film vs anaerobic adhesive: "Scene flexibility" difference in automotive interior bonding
2025-09-11
​From the perspective of curing conditions, TPU hot melt adhesive film does not need to rely on special environments, while anaerobic adhesives are severely restricted by "auerobicity". The curing principle of anaerobic glue is to undergo polymerization under conditions of lack of oxygen and catalyzed by metal ions (such as iron and copper). If it is in an environment where air circulation or metal substrates are not available, the curing speed will be greatly slowed down or even unable to cure. In automotive interiors, most bonding scenarios are "open" (such as bonding the door panel skin to PP substrate, and the ceiling fabric to the sponge), the air can freely contact the bonding surface, and the substrate is mostly non-metallic (PP, ABS, fabric, etc.), lacking metal ion catalysis, and additional catalyst is required when using anaerobic glue, and the curing time is as long as several hours, which is difficult to meet the needs of industrial production. The TPU hot melt adhesive film only needs to be melted by heating (120-160℃) and can be cured after pressurization and cooling. It does not need to rely on the ambient oxygen concentration or the base material. It can be cured stably in open or closed bonding scenarios, and the curing time only takes a few dozen seconds to a few minutes, adapting to the fast-paced needs of the interior production line.
