What are the characteristics of TPU film and in what fields does it have different applications? Let's learn about TPU film together today.

TPU film 

1. What is TPU film

TPU, short for Thermoplastic polyurethanes, is also known as PU thermoplastic. It is a linear block copolymer composed of oligomer polyol soft segments and diisocyanate-chain extender hard segments. TPU film is a film made from TPU granules through special processes such as calendering, casting, film blowing, and coating. TPU film is an important application form of TPU material.


2. Characteristics of TPU film

TPU film is a functional film with unparalleled characteristics of high strength, good toughness, cold resistance, oil resistance, aging resistance, weather resistance, environmental protection, non-toxicity, and decomposability that other plastic materials cannot match. It also has many excellent functions such as high waterproof and moisture permeability, windproof, cold-proof, antibacterial, warmth retention, UV resistance, and energy release, and is widely used in various fields.


3. Application of TPU film in different fields

TPU film has both the processability of plastic and the high elasticity of rubber, and has many advantages. In the field of shoe materials, TPU film upper materials can be directly bonded and pressed with the shoe body by using the excellent bonding properties of its underlying TPU hot melt adhesive film, without the need for sewing processes, providing good comfort and durability for the shoe materials. In the medical field, TPU film can be used to manufacture wearable devices such as blood pressure monitoring belts and heart monitors, which improves the patient's experience; it can also be used to make surgical gowns, protective clothing, etc., to provide protection for medical staff. In terms of automotive interiors, as a protective film for automotive paint, TPU film can resist stone impact, bird droppings corrosion, ultraviolet radiation, etc., and extend the service life of the paint; its flexibility means that TPU film can fit the body curve well without affecting the beauty of the vehicle. It is also used in automotive interior parts, seats, airbag covers and other parts to improve the comfort and safety of the car. In the field of construction, TPU waterproof membrane shows its unparalleled advantages in modern construction projects, especially in the waterproofing treatment of roofs, walls and basements. It can not only effectively prevent moisture penetration and extend the service life of buildings, but also adapt to various complex shapes of base surfaces, ensure the integrity of the waterproof layer, and has good weather resistance and flexibility.

With the development of science and technology, TPU film has also been innovatively applied in the field of smart wearable devices. For example, TPU film is used to make smart watch straps, which provide a soft and comfortable touch while maintaining product durability. In addition, in terms of electronic product protection, TPU film is often used in mobile phone screen protectors. Its self-healing ability means that minor scratches can disappear on their own within a certain period of time, reducing the frequency of replacing the protective film; TPU film provides a thin and strong protective layer for portable devices such as tablets and laptops, helping to reduce damage caused by accidental falls or impacts.

 

Innovative applications of TPU films in consumer electronics 3C and smart wearable devices

With the popularity of portable electronic products such as smartphones and smart watches, the requirements for waterproof and dustproof products are getting higher and higher. TPU waterproof film has become an ideal choice for protecting electronic products from damage by water and other liquids due to its ultra-thinness, high transparency and good touch.TPU films have innovative applications in the field of smart wearable devices. Wanhua Chemical brought innovative TPU solutions to the 2021 Smart Wear Forum. Based on customer needs, it focused on introducing four TPU product series for smart wearables: ultra-soft, antibacterial, aliphatic and bio-based, which were widely recognized by the guests on site. Among them, the ultra-soft material gives the wristband excellent low-temperature comfort; the antibacterial series has excellent resistance to environmental discoloration; the innovative molecular structure design aliphatic series not only provides excellent anti-yellowing performance, but also improves the design flexibility of color products; and the bio-based series content can reach up to 75wt%, which helps reduce carbon emissions and energy consumption.TPU filmsThermoplastic polyurethanes

Advantages of TPU membrane in the construction field

In the field of construction, TPU waterproof membrane shows its unparalleled advantages. TPU waterproof membrane not only has high strength, high elasticity, excellent wear resistance and weather resistance, but also has excellent waterproof, oil-proof, anti-pollution and antibacterial properties. In the waterproof treatment of roofs, walls and basements, TPU waterproof membrane can effectively prevent moisture penetration and extend the service life of buildings. It can adapt to various complex shapes of base surfaces, ensure the integrity of the waterproof layer, and has good weather resistance and flexibility.

The role of TPU film in automotive interior

In the field of automotive interiors, TPU films are gradually becoming an important choice for improving the aesthetics and durability of interiors. TPU films have excellent wear and scratch resistance. In the interior environment, seats, door panels, center consoles and other parts are often rubbed and scratched by passengers' clothing, handbags, keys and other items. TPU protective films can effectively resist the erosion of these external forces and prevent scratches and wear on the interior surface, thereby maintaining the original texture and aesthetics of the interior.

TPU material has good elasticity and can adapt to the slight deformation of interior parts, ensuring that the protective film fits tightly to the interior surface without leaving any gaps. In addition, some high-end TPU protective films also have self-healing capabilities, which can automatically repair minor scratches or damage, maintaining the integrity and beauty of the protective film.

The surface of the TPU protective film has been specially treated to have good waterproof and anti-fouling properties. Water drops falling on the film surface will form water beads and slide down, making it difficult to penetrate; stains are also difficult to adhere to the film surface, making it easy to clean and maintain. This not only maintains the cleanliness of the car environment, but also reduces the cleaning burden of interior materials.

During the installation process, the TPU protective film is usually fixed to the interior parts by adhesive bonding. This installation method is simple and quick, and does not require complicated tools and techniques. At the same time, when the protective film needs to be replaced or removed, it will not cause damage to the interior materials.TPU filmTPU filmsThermoplastic polyurethanes

With its unique properties, TPU film plays an important role in the fields of medical treatment, automotive interior, construction and smart wearable devices, and has broad development prospects in the future, moving towards high performance, personalization and environmental protection.
