TPU Film – Advantage and Disadvantage

TPU film is made by processes such as calendering, extrusion, blowing, and coating based on TPU pellets. It is widely used in sports shoes, such as trademark decoration, airbags, cushions, and oil bags on the sole and upper. Nowadays, there are two trends in the application of TPU film in sports shoes. One is the popular trend of women’s sandals, which uses high-transparent TPU film directly cut, screen printed with color, or laminated with fabric to form a mesh fabric, high-frequency formed and bonded on the upper, with both functional and decorative effects. The other is to use waterproof and breathable TPU film laminated with shoe materials to achieve the effect of waterproof and breathable.

Advantages

Good flexibility: TPU film has good flexibility and can remain intact under large deformation. This is particularly important in applications where materials need to be elastic, such as protective equipment and sports equipment.

Strong plasticity: TPU film has good plasticity and can be processed and formed by heating, pressure, and other methods, suitable for the manufacture of various complex-shaped products. This is particularly important in applications where materials need to have shaping ability, such as car interiors and shoes.

Good wear resistance: TPU film has good wear resistance and can maintain a smooth surface for a long time. This is particularly important in applications where materials need to be durable, such as electronic product shells and handbags.

High transparency: TPU film has good transparency and can transmit more light, making the material surface present clear patterns. This is particularly important in applications where materials need to have good visual effects, such as mobile phone screen protectors and advertising light boxes.

Disadvantages

Poor temperature resistance: TPU films is prone to softening and deformation in high-temperature environments, making it unsuitable for applications where materials need to have high temperature resistance. This is particularly important in applications where materials need to have high temperature resistance, such as car engine covers and oven liners.

Easy aging: TPU films is prone to aging and deterioration after long-term use, with surface cracking, yellowing, and other phenomena affecting aesthetics and service life. This is particularly important in applications where materials need to have long-term service life, such as outdoor billboards and public facilities.

In summary, TPU film has advantages such as good flexibility, strong plasticity, good wear resistance, and high transparency, but also has disadvantages such as poor temperature resistance and easy aging, which need to be selected according to specific application scenarios.
