According to commonly used special treatment methods,
waterproof zippers can be divided into coating waterproof zippers, PVC film waterproof zippers, waterproof agent immersion, TPU film and other categories.
Waterproof zipper with TPU film: TPU is an environmentally friendly high molecular polymer. The Chinese name is thermoplastic polyurethane, also known as waterproof and moisture-permeable membrane. It is a new type of environmentally friendly material. This is a major breakthrough in the application of waterproof and breathable fabrics. It overcomes many shortcomings 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 future material. TPU film is a film made of TPU pellets through a special process. It inherits the excellent properties of TPU and has a wide range of applications. Because TPU overcomes many defects of PVC, TPU film waterproof zipper is also superior in performance than PVC waterproof zipper. To sum up, the waterproof zipper with TPU film has the characteristics of cold resistance -40℃, high temperature 100℃, waterproof, breathable, low temperature resistance, and good softness. It is a high-end product among waterproof zippers.
PVC film waterproof zipper: 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 this film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. There are two reasons why PVC materials can be widely used: One is the unique properties of PVC (rainproof, fire-resistant, antistatic, and easy to form), and the other is the low input and high output characteristics of PVC. PVC waterproof zipper is the use of PVC waterproof characteristics.
What are the characteristics of waterproof zipper?
Waterproof zipper is a branch of nylon zipper. It is a nylon zipper with some special treatments, which can play a waterproof function when it encounters rain. Waterproof zippers are widely used, and are suitable for: cold-proof clothing, ski clothing, down jackets, sailing suits, diving suits, tents, vehicle and boat covers, raincoats, motorcycle raincoats, waterproof shoes, firefighting clothing, luggage, jackets, fishing clothing and other waterproof related products .
What should I pay attention to when choosing a good quality waterproof zipper?
Waterproof effect, the size of the seam is directly related to the waterproof effect of the waterproof zipper, too big obviously can not achieve the waterproof effect, and loses the meaning of the waterproof zipper itself.
The waterproof zipper film does not tear. No matter it is 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 lasting waterproof effect.
The color difference of colored
waterproof zippers should be small. The difference between the color of the zipper tape and the fabric is the color difference. The color difference between the color of the film surface and the color of the tape surface is controlled within 5%.
Service life, the quality of the glue film attached to the waterproof zipper is directly related to the service life of the waterproof zipper.
The surface of the waterproof zipper film is flat and delicate, with a smooth feel similar to leather, which is the appearance of high-quality waterproof zipper.
The degree of smoothness is generally believed that the better the smoothness of the zipper, the better the quality of the waterproof zipper.
Waterproof zipper needs to be environmentally friendly and must pass the OEKO-TEX100 standard.
