TPU hot melt adhesive film is not resistant to heat, and how many degrees of high temperature can it withstand?

    TPU hot melt adhesive film is one of the more common hot-melt adhesive films, because it is relatively soft and has good washability, so for the clothing industry, TPU hot melt adhesive film is used to bond fabrics to each other. Yes, it will be better. For manufacturers of related fabrics, although most TPU hot melt adhesive films are applicable, they are still different, so we must pay attention to careful selection when choosing.

    Almost all types of TPU hot melt adhesive films can be applied to the bonding of various fabrics. However, different models will have different characteristics for different types of fabrics, so the selection needs to be analyzed and selected according to the specific characteristics of the fabric. For fabrics with high elastic requirements, it is better to use medium and high temperature type TPU hot melt adhesive film for fabric compounding; if the fabric itself is not very elastic and needs to be compounded at low temperature, it is best to choose low temperature type .

    Many people who use TPU hot melt adhesive film or want to know about TPU hot melt adhesive film have a doubt, that is, whether TPU hot melt adhesive film is heat-resistant, and how many degrees of high temperature it can withstand. It is inevitable that some irresponsible manufacturers or companies on the Internet will say that TPU hot melt adhesive film is heat-resistant, which is not rigorous. Let's briefly talk about it below.

    From the characteristics of the TPU hot melt adhesive film itself, the heat resistance of the TPU hot melt adhesive film is poor, because it is a thermoplastic material that needs to be heated and melted, and then cooled and hardened to form a bond. The initial melting point of the common TPU hot melt adhesive film is generally between 40°C and 120°C, so in theory, the heat resistance is about 120°C. But in fact, when it does not reach 120°C, the TPU hot melt adhesive film may soften to a certain extent, so in fact, the temperature resistance will be lower than this temperature, that is, around 100°C, which may be the current conventional TPU. The highest value of hot melt adhesive film products.

    What are the advantages of TPU hot melt adhesive film raw materials

    TPU hot melt adhesive film material is low temperature resistant and soft. It has a softer touch and is ideal for fabric bonding and integration in the apparel industry. No irritation and foreign body sensation.

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.
