This is a major breakthrough in the application of waterproof and breathable fabrics, which overcomes many of the drawbacks of PVC waterproof zippers. It not only has most of the characteristics of rubber and ordinary plastics, but also has excellent physical and chemical properties, so it is also called future material. The TPU film is a film made by a special process using TPU pellets. It inherits the excellent physical properties of TPU and has a wide range of applications.

(2), PVC film waterproof zipper: The main material used in this product is PVC, the main component is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness and ductility. The uppermost layer of the film is lacquer, the main component in the middle is polyvinyl chloride, and the lowermost layer is a back-coated adhesive. PVC materials can be widely used for two reasons: First, the unique properties of PVC (rain, fire, antistatic, easy to form), and second, the low input and high output of PVC.
