2 0 1 6 • WRAPS • 109 Why Polyurethane for Automotive PPF? For years, thermoplastic polyurethane (TPU) has been known for and widely used as an abrasion-resistant protec- tive material. Hardwood floor finish is an excellent example of liquid poly- urethane's long-lasting beauty and durability. Extruded TPU film performs a simi- lar protective function. Over the last decade, aliphatic polyurethane-based paint protection films (PPF's) have enjoyed tremendous success in pre- serving the finish of cars and trucks the world over. One reason is that this high-performance polymer has no plasticizers, is inherently resistant to ultraviolet radiation and retains its crystal clear finish without yellowing over time. It remains flexible over the life of the film and readily conforms to the contours and edges of the vehicle. Polyurethane PPF's are abrasion, impact and chemical resistant, and proven to perform well in both hot and cold environments. These films even have self-healing properties. For these reasons, polyurethane film is the predominant material used for automotive paint protection films. A similarly formulated product is produced as a protective film for electronic device displays. The fact that TPU contains no environmentally harmful halogens or phthalates is another plus. Visit
