What is the composite process of TPU composite film?

TPU composite film is a composite film made of thermoplastic polyurethane material. It is widely used in various industrial fields due to its excellent physical properties and chemical stability. Composite technology mainly involves combining TPU materials with other materials (such as cloth, leather, paper, etc.) through specific processes to improve the performance of the product or give it new functions.

The composite process of TPU composite film usually includes the following steps:

1. Surface treatment: In order to enhance the bonding performance between the TPU film and the substrate, the surface of the substrate needs to be pre-treated, such as cleaning, grinding or chemical treatment, to remove surface impurities and oil stains and improve surface energy.

2. Gluing: Apply specific glue evenly on the surface of the TPU film or substrate. The choice of glue depends on the type of TPU film and substrate, as well as the required composite strength and temperature resistance.

3. Composite: Align and press the TPU film coated with glue with the base material, and solidify the glue by hot or cold pressing to achieve a tight combination of the TPU film and the base material.

4. Post-processing: After the composite is completed, some post-processing steps may be required, such as cutting, trimming, heat setting, etc., to ensure that the size and shape of the composite film meet the requirements and to improve its durability.

5. Quality inspection: Finally, quality inspection is conducted on the composite film, including performance tests such as bonding strength, temperature resistance, chemical resistance, etc., to ensure that the product meets the predetermined quality standards.
