What is TPU PPF?
TPU stands for thermoplastic polyurethane. In automotive PPF, the TPU body is normally only one part of the finished product. The final film also depends on a functional top coating, pressure-sensitive adhesive, release liner, coating quality, winding and converting control.
Why TPU is used in PPF
TPU is selected when the film needs to conform to compound curves, recover after stretching, absorb normal road abrasion and maintain a transparent flexible layer over painted surfaces. Exact behavior still varies with TPU grade and finished-film design.
