1 kinds of introduction

According to the commonly used characteristic treatment methods, waterproof zippers can be divided into coating waterproof zippers, PVC film waterproof zippers, waterproof agent soaking, TPU film and other categories.
(1) Waterproof zipper with TPU film: TPU is an environmentally friendly polymer, the Chinese name is thermoplastic polyurethane, also known as waterproof and moisture-permeable film, which is a new type of environmentally friendly material. This is a major breakthrough in the application of waterproof and breathable fabrics, which overcomes many defects 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 the material of the future. TPU film is a film made of TPU pellets through a special process. It inherits the excellent physical properties of TPU and has a wide range of applications. Because TPU overcomes many defects of PVC, TPU film waterproof zipper is also superior to PVC waterproof zipper in terms of performance. To sum up, the waterproof zipper with TPU film has the characteristics of cold resistance -40 ℃, high temperature resistance 100 ℃, waterproof, breathable, low temperature resistance, good softness, etc. It is a high-end product in waterproof zipper.
(2) Waterproof zipper with PVC film: The main material used in this product is PVC, the main component is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness and ductility. The top layer of the surface of this film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is a back coating adhesive. There are two reasons why PVC materials can be widely used: one is the unique properties of PVC (rainproof, fire resistance, antistatic, easy to form), and the other is the characteristics of low input and high output of PVC. PVC waterproof zipper takes advantage of the waterproof properties of PVC.
(3) Coated waterproof zipper: It is characterized by no falling off, no whitening, no embrittlement, low temperature resistance of minus 70 degrees Celsius, environmental protection, softness, and good waterproofness.
2 Notes
edit
1. Waterproof effect, the size of the middle seam is directly related to the waterproof effect of the waterproof zipper. If it is too large, it will obviously not have the waterproof effect and lose the meaning of the waterproof zipper itself.
2. The waterproof zipper film does not tear. No matter in the case of low temperature or repeated washing, the waterproof membrane is not easy to fall off or tear, so as to ensure the waterproof effect for a long time.
3. The color difference of the colored waterproof zipper should be small. The difference between the color of the zipper tape and the fabric is the color difference. The color of the film surface and the color of the tape surface should be controlled within 5%.
4. Service life, the quality of the film attached to the waterproof zipper is directly related to the service life of the waterproof zipper.
5. The surface of the waterproof zipper film is smooth and delicate, with a smooth feeling similar to leather, which is the appearance of high-quality waterproof zippers.
