TPU film needs to pay attention to the following two points
​The deformation resilience of the TPU film refers to the property that the film can immediately return to its original shape after an external force is applied. Deformation rate and resilience refer to the degree of deformation of a unit volume sample after being subjected to vertical pressure, and the speed and degree of rebound after releasing the pressure, which are used to judge the resistance of the material to pressure. With the continuous deepening of research and development of TPU film​ products and the improvement of the technical level of TPU film industry, the application field of TPU film will also continue to expand.

TPU film needs to pay attention to the following two points

    The deformation resilience of the TPU film refers to the property that the film can immediately return to its original shape after an external force is applied. Deformation rate and resilience refer to the degree of deformation of a unit volume sample after being subjected to vertical pressure, and the speed and degree of rebound after releasing the pressure, which are used to judge the resistance of the material to pressure. With the continuous deepening of research and development of TPU film products and the improvement of the technical level of TPU film industry, the application field of TPU film will also continue to expand.

    First of all, it is the chemical resistance of TPU film. TPU film is not resistant to strong polar solvents and strong acid-base media. At a certain temperature, alcohols, acids, and ketones will swell and degrade polyurethane elastomers. Solvents such as dichloromethane and trichloroethylene will swell the TPU film at room temperature.

    On the other hand, it is necessary to mention the high temperature resistance of TPU film. Although the TPU film still exhibits its elasticity and toughness in a cold environment of minus 30 degrees, it does not perform well at high temperatures. A large amount of heat energy will be generated inside the TPU film, so its high temperature resistance is average, and the usual use temperature is between -30°C and 80°C. It is not recommended to use it in an environment higher than 130°C for a long time.

    TPU film is not only used for clothing, but its excellent performance, such as a wide range of hardness (60HA-85HD), wear resistance, oil resistance, transparency, and good elasticity, has attracted much attention. Moreover, it is widely regarded as a cost-effective and environmentally friendly polymer material. Therefore, new technologies, new products and new uses are constantly emerging. TPU film are widely used in the fields of pipes, films and sheets, cables, automobiles, construction, medicine and health, national defense, sports and leisure, shoes and hats, and packaging. and development prospects.

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.
