Both TPU and PU belong to polyurethane, but TPU belongs to thermoplastic polyurethane and is superior in performance to PU material. It is also the first material recommended by well-known invisible car ppf brands at present.
Invisible car clothing, commonly known as car paint protection film, is a transparent film with high transparency, toughness, and strength. It mainly acts on the car paint surface, similar to putting an invisible “coat” on the car, used to protect the car paint surface from external scratches, flying stones, bird droppings, acid rain, gum, exhaust gas, graffiti, and other damage to the car paint surface. After using a legitimate invisible car clothing, Car owners basically don’t have to worry about the paint being damaged anymore.
At present, the main materials of invisible car paint protection film are PVC, TPH, TPE, PU, TPU, and other materials.
PVC, also known as polyvinyl chloride, is the most common material for invisible car clothing among domestic brands, and its overall price is only around thousands of yuan. Although the price is cheap, PVC invisible car jackets do not have scratch self-healing, hydrophobic, and oil repellent functions. Moreover, due to their low elasticity, their strength and toughness are low, and their protective ability for the paint surface is insufficient. They need to be replaced after less than two years of use, and the adhesive layer also has fatal corrosiveness to the paint surface.
TPU is a thermoplastic elastomer with a wide hardness range (60HA-85HD), wear resistance, oil resistance, transparency, and good elasticity. It is widely used in daily necessities, sports goods, toys, decorative materials, and other fields. TPU can also replace soft PVC to meet the environmental requirements of more and more fields, and its outstanding performance and environmental concept are increasingly popular among people. At present, wherever PVC is used, TPU can become a substitute for PVC, but the advantages of TPU are unmatched by PVC. The invisible car clothing made of TPU material can achieve excellent performance such as scratch self-healing, long-term resistance to yellowing, and hydrophobicity, making it an invisible car clothing material that other materials in the market cannot match.
