Why can TPU hot melt adhesive film replace traditional glue in the adhesive industry and become the market darling?

    1. High profit. For example, the cost per square meter of wood boards bonded with TPU hot melt adhesive film is only a few cents higher than that of wood boards bonded with glue, but the added value of the product price is far greater than the cost increase caused by replacement. glue. value. This is the reason why the new polymer TPU hot melt adhesive film is replacing the traditional adhesive, which can bring better economic benefits to customers and increase the value of customers' products.

    2. Environmental protection. From the perspective of the enterprise's own environmental protection and safety, the use of polymer TPU hot melt adhesive film has more environmental protection and safety advantages. In the production process, the bonding workshop needs to use environmental protection treatment facilities, and the environmental protection investment and operation costs of the equipment are very expensive. Especially in the economically developed regions such as the Yangtze River Delta and the Pearl River Delta, more and more enterprises use glue production technology. Approval is difficult because glue is a dangerous product and requires a special warehouse for storing dangerous products, increasing environmental protection investment and potential safety hazards.

    TPU hot melt adhesive film has the following characteristics:

    1. Good, consistent and uniform bond thickness;

    2. Easy to process, no solvent, easy to process;

    3. Good adhesion to various objects;

    4. Thickness 0.1-0.203MM, color translucent/amber;

    5. Can be stamped into precise shape and size, suitable for pure manual or automatic application.

    application:

    TPU hot melt adhesive film can be bonded to various materials such as metal, plastic, paper, wood, ceramics, textiles, etc., and good results can be obtained by bonding on uneven surfaces; it is mainly used for nameplates, plastics, hardware, and metals of electronic products of bonding. Bonding and fixing of the shell, bonding and fixing of the reinforcement board, bonding and bonding of smart cards and chip passports, bonding of mobile phone window frames and front covers, bonding of camera battery slots, etc.

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.
