How much do you know about TPU film?
TPU film is a type of plastic film that is often used in our lives. It can be a good substitute for PVC film, and has greatly improved in terms of thermal insulation, wind resistance and durability. In addition, it is also widely used in textile fabric composite, medical breathable tape and other fields. This is more in line with the environmental protection standards advocated by our country. TPU film is widely used in brand decoration of sports shoes, such as soles, uppers, airbags, air cushions, oil bags, etc.

How much do you know about TPU film?

TPU film is a type of plastic film that is often used in our lives. It can be a good substitute for PVC film, and has greatly improved in terms of thermal insulation, wind resistance and durability. In addition, it is also widely used in textile fabric composite, medical breathable tape and other fields. This is more in line with the environmental protection standards advocated by our country. TPU film is widely used in brand decoration of sports shoes, such as soles, uppers, airbags, air cushions, oil bags, etc.

The adhesion between the TPU film and the adherend is mainly mechanical adhesion. After the surface is coated with adhesive, the TPU film penetrates into the pores of the adherend. After drying and curing, friction occurs between the TPU film and the adherend, increasing the bonding force between them.

TPU film is divided into low air permeability, medium air permeability and high air permeability according to the air permeability. The difference in ex-factory price is usually reflected in the difference in air permeability. In some high-end applications, high permeability can better achieve the breathability of the film, which is difficult for some low-permeability and medium-permeability TPU films to match. The thickness of the TPU film is different. The thickness of the TPU film that the manufacturer can customize is between 0.01mm and 0.04mm. The thicker the TPU film, the worse the air permeability. The thickness of theTPU film can be comprehensively selected according to their own needs.

With the continuous improvement of my country's production capacity, TPU film has formed export products and products in Taiwan Province of China. In my country, the supply of TPU film is in short supply, and the situation of oversupply has not yet appeared, and there is still a very great development prospect in the future. TPU film is the core use of TPU and one of the products with great development potential of TPU.

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.
