What aspects should be started when using hot melt adhesive film for compounding

    Among the many hot melt adhesive film products, the hot melt adhesive film, which is used for compounding of the same or different media, has outstanding adhesive performance. There are many hot melt adhesive film manufacturers on the market, and they can produce different types of hot melt adhesive films according to the requirements of users. For the demand side, there are many details that need to be paid more attention to, whether it is purchase or application, so that the composite effect of the product can be exerted better.

    When using hot melt adhesive film for compounding, what aspects need to be started

    Match type

    There are many types of adhesive films that hot melt adhesive film manufacturers can produce. When using them to compound different types of media, there are certain differences in the performance of the hot melt adhesive films used. Therefore, when purchasing an adhesive film, it is necessary to pay attention to the comprehensive consideration of the adhesive force of the hot melt adhesive film and the materials that can be used. Only when the type of hot melt adhesive film selected is more suitable for the material to be bonded, the final bonding effect can be better.

    Do a good job of bonding surface treatment

    After the hot melt adhesive film manufacturer produces the adhesive film, the customer needs to treat the composite interface before using the adhesive film for compounding. If there are stains on the surface to be bonded or serious potholes, the overall adhesion will naturally be affected. Therefore, before compounding, it is very important to do a good job of preparatory work on the surface to be compounded.

    Control the bonding temperature and duration

    When using different types of hot melt adhesive films, there are certain differences in the corresponding bonding temperature. The technical staff of thehot melt adhesive film manufacturer revealed that when using different types of adhesive films for compounding, if the temperature is too low, it will cause insufficient melting and poor bonding performance. If the temperature is too high, it will also cause a lack of glue in the entire film layer, resulting in a decrease in adhesion. In the actual application of hot melt adhesive film, it is very important to pay attention to the adjustment and do a good job of temperature control.

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.
