What are the uses of TPU hot melt adhesive film?

TPU hot melt adhesive film will always appear in unexpected places, and its use must be beyond your imagination. Common adhesives in daily life, such as tape, glue, glass glue, etc., can only be said to be popular adhesives in life, but the application fields of TPU hot melt adhesive film are mainly concentrated in industry rather than family life.

We all know that glue is used to bond objects, hot melt adhesive film is a kind of adhesive, naturally used to bond materials. It's just that this adhesive is slightly different from the adhesives commonly used in our daily lives, because it needs heating to have adhesion. The common hot melt adhesive film tape, glue, and glass glue in daily life can basically be bonded without external conditions, but the hot melt adhesive film can only be bonded after it reaches the melting point.

First of all, in the sports shoe industry, users need to transfer the TPU hot melt adhesive film to the surface of the material through a thermal transfer machine, and after drying, electro-engrave and perforate each customized part. This method is called in our industry. Used for seamless bonding of shoe uppers.

Then there is the clothing industry. According to the requirements of the fabric, the TPU hot melt adhesive film is cut into corresponding widths, pressed on the surface of the fabric at high temperature until the TPU hot melt adhesive film is fully attached, and then pressed at high temperature as required. This method is called thermal-thermal seamless connection.

Finally, in the luggage industry, the TPU hot melt adhesive film is attached to the surface of the material, the release paper is removed after curing, and then transferred to the surface of the adhesive material by thermal transfer.

The above materials are varied. According to the temperature resistance and folding resistance of the materials used, select the TPU hot-melt adhesive film with a relatively melting point, and then mass-produce it after testing according to the process requirements.

Low temperature TPU hot melt adhesive film is inelastic, whille high temperature TPU hot melt adhesive film has good elasticity. TPU hot melt adhesive film has some common characteristics of polyurethane materials, such as soft materials, cold resistance, and water resistance. Compared with other materials, TPU hot melt adhesive film has a softer feel under the same thickness, which is very suitable for the composite bonding of textile fabrics in the clothing field.

The fabric bonded by TPU hot-melt adhesive film is very comfortable to wear on the human body, without feeling of plastic or foreign body. All these are due to the characteristics of its main component polyurethane. The above is the introduction of the main ingredients of TPU hot melt adhesive film. Due to the characteristics of the material, TPU hot melt adhesive film shows good washing resistance, flexibility and good elasticity. Suitable for textiles, leather, TPU hot melt adhesive film. This material has good adhesion and is widely used in clothing, home building materials, shoe materials and other fields.

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.
