Difference between PPF and TPU for paint protection film: Paint protection film is a high-performance, environmentally friendly new-type film widely used in the automotive film beauty and maintenance industry. It is a common name for transparent paint surface protection film, also known as clear bra. TPU refers to thermoplastic polyurethane, which is one type of material used for paint protection films. Below are the functions of paint protection film: 1. Protection: Crystal clear transparency, wear resistance, scratch resistance, yellowing resistance, and impact vibration reduction. After installation, it provides protection against tar, tree sap, insect fluids, bird droppings, acid rain, and saltwater corrosion. 2. Repair: Maintains metal, ABS plastic, paint surfaces, and organic materials, and can repair minor scratches on poor-quality materials. 3. High-temperature resistance: Withstands water impact at 5MPA, high temperatures up to 150 degrees Celsius, and low temperatures down to -80 degrees Celsius; excellent composite materials maintain product performance on complex surfaces.
I've always valued car protection, and after applying paint protection film (PPF) several times, I've learned: PPF is the general term for invisible car bras, a film that protects the car's paint from scratches and gravel impacts. TPU, on the other hand, is one of the mainstream materials—a thermoplastic polyurethane known for its good elasticity and ability to self-heal minor scratches, such as automatically repairing slight abrasions under sunlight. In contrast, ordinary PPF might use cheaper PVC or PU materials, which have poor weather resistance, turning yellow or cracking after a few years and affecting the car's appearance. I've been using TPU-based PPF for two to three years now—it's more durable, has strong UV resistance, and keeps the paint shiny. However, it's crucial to have it installed by a professional shop to ensure no bubbles or misaligned edges, as improper application can diminish its effectiveness. This is definitely worth noting.
