Nowadays, many owners in order to protect their vehicles beautiful original car paint, will be pasted for the car transparent car film, now many transparent car film are made of TPU this material, this material car film than PVC or TPH car film will be more durable, more beautiful, there are many different types of TPU, such as the TPU Matte, self-repairing TPU and so on. So the question comes, how is a roll of TPU Car Film made?

TPU (thermoplastic polyurethane) Paint Protection Film is a kind of advanced automotive protection products, it has high transparency, scratch resistance, UV resistance and other characteristics. The production process usually includes the following key steps:

1. Raw material preparation

The production of TPU transparent car film first needs to prepare high-quality TPU particles as the main raw materials, which may come from the synthesis process of TPU. In addition, necessary additives need to be added to improve the performance of the TPU, such as increasing transparency, enhancing toughness or improving adhesion.

2. Melt mixing

The prepared TPU particles and additives are placed in a high temperature melt mixer for heating and mixing until a uniform melt is formed. This process requires strict control of temperature and pressure to ensure the full fusion of TPU components and the stability of the chemical reaction.

3. Extrusion molding

The molten TPU mixture is extruded through a special mold to form a sheet or coil. In this process, the design of the mold is crucial, which determines the thickness, shape and surface texture of the final product. For transparent car film, mold design needs to ensure the smoothness and transparency of the product.

4. Cooling and shaping

The extruded product needs to be quickly passed through the cooling system to make the TPU quickly solidified and formed. The speed and manner of cooling affects the physical properties of the product and therefore requires precise control.

5. Cutting and packaging

The TPU transparent car film after cooling and shaping needs to be cut to meet the needs of different models. After the cutting is completed, the product will be packaged, usually using dust-proof and moisture-proof packaging materials, and attached with instructions and precautions.

In this way, a standard TPU paint protection film is produced, and subsequent quality testing and logistics will be completed together to bring the best use experience to customers

The entire production process requires a high degree of automation and precise control to ensure product quality and consistency. In addition, environmental protection and sustainable development are also important considerations in modern production processes, such as choosing recyclable or biodegradable materials, optimizing energy use, and reducing waste generation.
