TPU hot melt adhesive film is a very common environmentally friendly adhesive

    TPU hot melt adhesive film is a kind of adhesive product that is developing rapidly at present, and it is widely used. Regarding the formula of TPU hot melt adhesive film, it is prepared by mixing basic polymers, tackifying resins (tackifiers), waxes and antioxidants, and each ingredient has its effect. As the use of TPU hot melt adhesive film is becoming more and more common, TPU hot melt adhesive film has now been applied to some home improvement and building materials fields, such as the composite of decorative panels, wall coverings, curtains and other materials. Especially in the field of wall coverings, it has achieved relatively mature applications.

    TPU hot melt adhesive film needs to go through such a high-temperature melting process in the manufacturing technology process. In this process, we can improve and promote the volatilization of some harmful chemical substances to ensure that its active ingredients are safer. When the hot-melt adhesive film is used in manufacturing When the finished product and materials are compounded, no other harmful substances will volatilize even if they are re-analyzed and treated as a "high temperature" environment. Therefore, through the treatment of these two high-temperature links, it is to ensure that the TPU hot melt adhesive film is an environmentally friendly adhesive that can be non-toxic and harmless.

    In fact, people who have a little knowledge of adhesives will know that TPU hot melt adhesive film is a form of hot melt adhesive film. Hot-melt adhesive film adhesive is a very common environmentally friendly adhesive. It is different from trialdehyde adhesives that have formaldehyde problems, and is also different from solvent-based adhesives. It has solvent volatilization problems. It is a real adhesive. Environmentally friendly adhesive products, so it has such a wide range of applications.

    The reason why traditional adhesives are not environmentally friendly is either because the ingredients between them contain toxic substances such as formaldehyde, or because they need to use toxic solvents to stick together. Then analyze from these two aspects. First, polyurethane is a safe and harmless component. Secondly, it has viscosity after heating, which belongs to thermoplastic adhesive and does not use organic solvents. From these two aspects, we can conclude that TPU hot melt adhesive film is Environmentally friendly and harmless to human body.

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.
