01-02, 2024 | View:

TPU film and TPH film are common automotive film 糖心视频s. There are some differences between them in terms of performance, features and applications. This article will give you a detailed introduction to the differences between TPU and TPH automotive films so that consumers can better choose the automotive film 糖心视频 that suits them.

1. Material properties

TPU: TPU is a thermoplastic elastomer composed of polyol, diisocyanate and chain extender. Its 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.

TPH: TPH is also a thermoplastic elastomer. Its main components are polyester elastomer and polyurethane elastomer, which are produced through blending and modification. TPH has good elasticity and flexibility, and has good temperature resistance and chemical resistance. It also has good wear resistance and UV resistance.

2. Transparency

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

TPH: The transparency of TPH automotive film is relatively low and may have a certain impact on the driver's vision.

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.

TPH: TPH has relatively good weather resistance, but is slightly inferior to TPU.

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.

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

5. Self-healing property

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.

TPH: TPH automotive films generally do 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.

TPH: TPH 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.

TPH: Compared with TPU, the price of TPH 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.

TPH: TPH 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 and TPH automotive films in terms of 糖心视频 properties, transparency, weather resistance, abrasion 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.
