The application scenarios of TPU films are very wide, the following are some of the main application areas

    Medical field:

    As TPU has good biocompatibility and physical properties, it is widely used in the medical field. For example, it is used to make artificial heart assist devices, artificial blood vessels, artificial skin and other medical machinery.

    TPU films can also be used to make surgical instrument coatings, artificial heart valves and drug delivery systems, making an important contribution to the development of medical technology.

    Shoe Material Industry:

    TPU plastic film is widely used in the shoe material field due to its good toughness and abrasion resistance, providing excellent comfort and durability.

    Electronic products protection:

    The strength of TPU film can be adjusted according to the actual situation, which makes it mainly suitable for the protective case design program of 3C new products.

    It can also be used to make protective films for electronic products, keyboard stickers, cell phone cases, etc. to protect the shells of electronic products from scratches and damage.

    Piping industry:

    The flexibility and aging resistance of TPU films make them particularly suitable for the piping industry, especially in environments where corrosion and oxidation need to be avoided.

    Packaging industry:

    The openness and ductility of TPU film makes it used in the plastic film industry, such as food packaging film and drug packaging film.

    It is also commonly used in food packaging, pharmaceutical packaging, industrial product packaging, etc., because of its good flexibility and tear resistance can protect packaging materials from damage and pollution.

    Other industrial applications:

    TPU plastic film can be used to make inflatable raw materials (such as lifeboats, airbags, etc.).

    In the field of construction, it can be used in building covering and isolation materials, such as as roof waterproof layer, building membrane and isolation membrane.

    In the automotive and aviation fields, it can be applied to the manufacture of automotive interior and exterior parts, such as seat covers, floor mats, door trims, etc.

    Smart Wearable and New Energy:

    TPU film has applications in smart wearable devices, such as smart bracelets, smart watches and other devices such as straps and cases.

    In the field of new energy, such as solar panels and wind power blades, TPU film is widely used because of its excellent weather resistance and abrasion resistance.

    Daily life products:

    TPU film is also used in apparel and textiles, such as garment linings, fabric coatings, and waterproof clothing.

    It is also used in sporting goods, such as sports shoes, sportswear, sports equipment, etc. It is popular for its good elasticity and wear resistance.

    With the continuous development and innovation of science and technology, the application range of TPU film will continue to expand, bringing innovation and convenience to more 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.
