TPU Film in Automotive Applications: Paint Protective Films

Thermoplastic Polyurethane (TPU) film, and particularly in its capacity of paint protective films(PPF), which serve many people in the automotive industry. PPFs protect vehicle surfaces from getting scratches, chips or worn out by weather, thereby allowing the vehicles to maintain their good look and resale value. Since a laminated coating does not deteriorate the appearance of the protective film, high light transmittance of TPU makes it possible through the paint finish layer.

The great elasticity and flexibility of TPU enables the ply to smoothly bend along every contour and line of the vehicle, enabling all round and all angled protection. This pliability does not only make it possible to apply the film, but also take it off without harming wherever it is placed. TPU’s wear resistance is also very pronounced. It protects paints from minor abradants like tiny pebbles or particulate matter during normal use.

The self-healing property of the TPU film is one such application where this polymer excels, especially in the automotive sector. Small cut marks in the film can be removed when heated, which assists greatly in the maintenance of the vehicle’s exterior as though the vehicle has never left the showroom. Furthermore, the TPU’s tear strength allows the film to stretch or be hit substantially without breaking and thereby guarantees long-lasting stability of coverage.

Thanks to the chemical properties of TPU, it can safely endure many automotive cleaning substances, oils, and other chemicals encountered in the course of road use, thus maintaining the integrity and safe use duration of the film while demonstrating good resistance. When applied, it does not change the original colour and shine of the paint, and, on the contrary, improves the external view due to its own degree of transparency and glossiness.

At the same time, TPU film is built to endure temperatures ranging from extremely low to exceedingly high with ease of maintenance. Regardless of whether the temperature is high or low, the characteristics of the TPU resin are not affected, so the protective capabilities of the film against harsh weather conditions are achieved.
