TPU film can still maintain good elasticity at -35 degrees

    TPU film is not only suitable for all kinds of fabrics, but also can produce products with clear outline and stable size by vacuum thermoforming method. With the improvement of China's environmental protection awareness, the application of TPU film is becoming more and more extensive. With excellent biocompatibility, non-toxic, no allergic reaction, no local irritation, no pyrogen, it is widely used in medical, hygiene and other related products as well as sports and protective products.

    TPU film has outstanding cold resistance. Due to its low glass transition temperature, TPU film can still maintain good elasticity and mechanical properties at -35 degrees, and can be used in outdoor and other cold-resistant products.TPU film products have excellent load-bearing capacity, impact resistance and shock absorption properties. Excellent cold resistance: TPU film has a low glass transition temperature and still maintains good elasticity, flexibility and other physical properties at minus 35 degrees. Good processing performance: TPU film can be processed using common thermoplastic material processing methods, such as injection molding, extrusion, calendering, etc. At the same time, TPU films and certain polymer materials can be processed together to obtain polymer alloys with complementary properties. Resistant to oil, water and mold. Thermoplastic polyurethane rubber (TPU) is not perfect. Its main disadvantages are: large internal heat generation and general high temperature resistance. The normal operating temperature range is -40~120C. If it needs to be used for a long time under high-frequency oscillation or high temperature conditions, corresponding modification measures must be taken in structural design or formula.

    TPU film is widely used in sports shoes: sole and upper trademark decoration, air reading, air cushion, oil bag, etc. Nowadays, there are two major trends in the application of TPU film in sports shoes: - is the popularization of Nike sports shoes, that is, the screen printing color of TPU film, and then high-frequency molding and bonding on the upper for decoration to achieve special decorative effect. Use waterproof and moisture-permeable TPU film and shoe cloth to achieve waterproof and moisture-permeable effect.

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.
