1, TPU membrane waterproof zipper: TPU is an environmentally friendly polymer material, which is called thermoplastic polyurethane in Chinese, also known as waterproof and moisture permeable membrane, and it is a new type of environmental protection information. This is a major breakthrough in the application of waterproof and breathable fabrics and overcomes many shortcomings of PVC waterproof zippers. It not only has most characteristics of rubber and general plastics, but also has excellent physical and chemical functions, so it is also called future data. TPU film agent is a film agent made of TPU particles through special process. It inherits the excellent physical properties of TPU and is widely used.

2. Because TPU overcomes many shortcomings of PVC, TPU film waterproof zipper is also superior to PVC waterproof zipper in function. To sum up, TPU film waterproof zipper has the characteristics of cold resistance -40℃, high temperature resistance 100℃, waterproof and breathable, low temperature resistance and good flexibility, and it is a high-end commodity in waterproof zipper.

3. PVC film waterproof zipper: The primary information used in this product is PVC, and the primary component is PVC. Other components are added to enhance its heat resistance, patience and ductility. The top layer of this film is paint, the main component in the middle is PVC, and the bottom layer is adhesive.

4.PVC materials can be widely used for two reasons: PVC has the same function (rain-proof, fire-proof, antistatic and easy to form), and PVC has the characteristics of low input and high output. PVC waterproof zipper is the use of PVC waterproof characteristics.
