Application of TPU film technology in producing mobile phone film

TPU film, a thermoplastic polyurethane elastomer film, is widely used in the field of mobile phone protective films because of its excellent elasticity, wear resistance and high transparency. Mobile phone films produced using TPU film technology are often called hydrogel films or soft films. Their biggest feature is their super ductility and flexibility, which can perfectly fit the screen curvature of curved and folding screen mobile phones, achieving all-round coverage and protection without dead ends.

In terms of technology, TPU films are mainly produced by casting or calendering, and are then made into finished products through multiple processes such as coating, curing, and slitting. During the production process, the surface of the film will be hardened and anti-fingerprint coated to improve the scratch resistance and feel of the product.

The TPU mobile phone film has an automatic repair function. Slight scratches on the surface can heal and recover on their own in a short time, keeping the screen clear and translucent for a long time. At the same time, its good flexibility can effectively buffer external impacts and play a certain protective role on the screen. In addition, the TPU material is also resistant to yellowing, anti-fingerprints, and high light transmittance. It will not affect the display effect and touch sensitivity of the screen, bringing users an operating experience close to a bare screen.

With the continuous popularity of folding screen mobile phones, TPU film technology has broader application prospects in the field of mobile phone films. It has become the mainstream choice for curved screen and folding screen protective films. In the future, it will continue to be upgraded in the direction of wear-resistant coatings and antibacterial functions.
