Pay attention when using TPU hot melt adhesive film
​1. The film specifications produced by TPU hot melt adhesive film manufacturers are different, and the temperature requirements for compound processing will also be different. Therefore, with the help of adhesive film compounding, the temperature requirements will be relatively high, and the temperature is too high or too low, which may affect the final bonding effect. Therefore, it is very important to do a good job in temperature control during use.

Pay attention when using TPU hot melt adhesive film

    1. The film specifications produced by TPU hot melt adhesive film manufacturers are different, and the temperature requirements for compound processing will also be different. Therefore, with the help of adhesive film compounding, the temperature requirements will be relatively high, and the temperature is too high or too low, which may affect the final bonding effect. Therefore, it is very important to do a good job in temperature control during use.

    2. Although the first lamination is performed with the help of TPU hot melt adhesive film, the effect is not good, but the second hot pressing lamination can be carried out. But after repeated hot pressing, it will inevitably affect the viscosity of the film. Therefore, when using it, try to avoid performing secondary heat-pressing treatment on the same adhesive film, so as to better ensure the excellence of the final bonding effect.

    TPU hot melt adhesive film is an adhesive product, which is essentially a kind of plastic, made of composite materials, and is a kind of hot melt adhesive. TPU hot melt adhesive film can be well bonded to various materials with high bonding strength. Generally speaking, the characteristics of TPU hot melt adhesive film include high elasticity, high toughness, weather resistance, wash resistance, dryness, softness and good hand feeling, strong adhesion, good fit, various materials, and environmental protection. Widely used in leather shoes, microfiber, leather mobile phones, computer bags, coats, sports fabrics, plastics, paper, wood, ceramics, textiles, etc.

    When purchasing TPU hot melt adhesive film, be sure to specify the color of the TPU hot melt adhesive film used. When users use TPU hot melt adhesive film to compound different types of products, there will be certain differences in the requirements for appearance color. There is no special requirement for the appearance color of TPU hot-melt adhesive film for compounding some products. It is enough to choose light yellow TPU hot melt adhesive film, and its adhesion is much better than that of other colors of TPU hot melt adhesive film. However, if the adhered items have requirements for the appearance color of the TPU hot melt adhesive film, you need to choose the TPU hot melt adhesive film of the corresponding color according to the requirements.

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.
