In the field of car beauty and customization, color-changing films are favored by more and more car owners as a convenient and economical way to change the color of the car body. The mainstream color-changing film materials on the market currently include PVC (polyvinyl chloride), PET (polyethylene terephthalate), and TPU (thermoplastic polyurethane). Each material has its own unique characteristics and application scenarios. This article will analyze the material characteristics and selection guide of these three color-changing films in detail.
PVC color-changing film
PVC color-changing film, that is, polyvinyl chloride color-changing film, is the most common and popular color-changing film material on the market. PVC material has won a wide market share with its rich colors and low prices. PVC color-changing film has bright colors and a wide range of choices, which can meet the diverse needs of car owners for car body colors. However, PVC color-changing film also has some obvious disadvantages, such as poor durability and flexibility, and it is prone to fading, warping, cracking and other problems after long-term use. In addition, the environmental adaptability of PVC color-changing film is also weak, and it is easy to deform or produce chemical reactions in high or low-temperature environments, resulting in decreased viscosity.
Nevertheless, for car owners who pursue cost-effectiveness and short-term decorative effects, PVC color-changing film is still a good choice. It is affordable, easy to install, and can bring a new appearance experience to the vehicle in a short time.
PET color-changing film
PET color-changing film is relatively less mentioned in the market. In fact, PET appears more as a base paper or release film material in the color-changing film, rather than directly as a film material. PET base paper has a better finish and strength, making the color-changing film smoother during the laminating process, less likely to produce bubbles, and ultimately showing a better laminating effect on the car body. The overall texture and durability of the color-changing film with PET base paper are better than those of the traditional PVC color-changing film with paper base paper.
However, it should be noted that color-changing films with PET as the main material are relatively rare on the market. If they exist, they may provide better quality than PVC due to the superior physical properties of PET, but cost and popularity may limit their application. Therefore, when purchasing, car owners should clarify the specific role of PET in the color-changing film to avoid misunderstandings.
TPU color-changing film
TPU color-changing film is a high-end color-changing film material that has emerged in recent years, with thermoplastic polyurethane as the main component. TPU color-changing film has many excellent characteristics, such as bright colors, rich and diverse, customizable and small color difference; high toughness and strong wear resistance, excellent anti-scratch ability; self-repair function, small scratches can heal themselves under certain conditions; environmentally friendly and stable, long service life, and not easily affected by environmental changes.
Compared with PVC color-changing film, TPU color-changing film performs well in quality, weather resistance, toughness, etc. Its installation process is also relatively simple, using physical bonding, and does not require the use of special tools and equipment. However, the price of TPU color-changing film is relatively high, and the color variety is relatively small, mostly basic monochrome. In addition, due to its large thickness, the requirements for construction technology are also higher.
For car owners who pursue advanced protection and long-term use experience, TPU color-changing film is undoubtedly the best choice. It can not only provide comprehensive protection for the car body, but also meet the car owner's demand for personalization. It is a high-end product in the car beauty market.
