The difference between automotive film TPU and PU

12-28, 2023 | View:

TPU and PU are two common automotive film 糖心视频s. There are some differences between them in terms of performance, features and applications. Next, we will introduce you in detail the difference between TPU and PU automotive film.

1. Material properties

TPU: TPU is a thermoplastic elastomer whose molecular chain structure contains ester bonds and urea bonds. TPU has high strength, wear resistance, tear resistance and chemical resistance. It also has good flexibility and reshaping properties and can adapt to changes in the body's curved surface.

PU: PU is a polymer 糖心视频 composed of polyurethane segments and other additives. PU has excellent wear resistance, scratch resistance and chemical resistance. It also has good flexibility, but is slightly harder than TPU.

2. Transparency

TPU: TPU automotive film has high transparency and can provide a clear view without affecting the driver's vision.

PU: The transparency of PU automotive film is relatively low, which may have a certain impact on the driver's line of sight.

3. Weather resistance

TPU: TPU has excellent weather resistance and can resist the erosion of external factors such as ultraviolet rays, high temperature, humidity and chemical pollutants, maintaining long-term color stability and appearance quality.

PU: PU automotive film generally has poor weather resistance and is easily affected by ultraviolet rays and oxidation, leading to color fading and surface aging.

4. Wear resistance

TPU: TPU has excellent wear resistance, which can effectively resist scratches and wear in daily use, protect the surface of the car body from external damage, and extend the aesthetic life of the car body.

PU: PU automotive film also has good wear resistance, but it is slightly inferior to TPU.

5. Self-healing

TPU: TPU automotive film has self-healing properties, which can repair minor scratches and small damages, maintain the smoothness and gloss of the surface, and extend the service life of the film.

PU: PU automotive film generally does not have self-healing properties.

6. Installation difficulty

TPU: The installation of TPU automotive film is difficult and requires professional skills and experience to ensure good film effect and avoid bubbles, wrinkles and other problems.

PU: PU automotive film is relatively easy to install and can generally be installed relatively easily.

7. Price

TPU: Due to its higher performance and advantages, the price of TPU automotive film is usually higher.

PU: Compared with TPU, the price of PU automotive film is generally more moderate.

8. Application scope

TPU: TPU automotive film is mainly used in high-end models and cars with high appearance requirements, such as luxury cars, sports cars, etc.

PU: PU automotive film is suitable for general models and the needs of ordinary consumers, and is widely used in various types of cars on the market.

There are some differences between TPU automotive film and PU automotive film in terms of 糖心视频 properties, transparency, weather resistance, wear resistance, self-healing, installation difficulty, price and application scope. When choosing, consumers can consider these factors based on their own needs and budget, and choose the car film 糖心视频 that suits them.
