We know that waterproof zippers can play a waterproof function when it rains or encounter rain, and waterproof zippers are also used on seamless products. In this article, we will share with you the uses of waterproof zipper.
Generally speaking, waterproof zippers are divided into civil waterproof zippers, industrial waterproof zippers, and airtight and watertight zippers. And watertight and airtight products have relatively high requirements for waterproofing. In fact, waterproof zipper is also a kind of nylon zipper, which is specially processed nylon zipper. The special treatment of waterproof zipper includes attaching PVC, attaching TPU film, soaking in waterproof agent and coating waterproof zipper.
Now PVC waterproof zipper is the most widely used, and its main material is PVC and 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. Usually PVC can be divided into soft PVC and hard PVC. Soft PVC is often used for floors, ceilings and the surface of leather, because soft PVC contains softeners, this is also the difference between soft PVC and hard PVC. And it is easy to become brittle and difficult to store, so its use range is not wide. Rigid PVC does not contain softener, so it has good flexibility, and it is easy molding and not easy to be brittle. Basically it is non-toxic and non-polluting, and has long storage time. So, it has great development and application value and a broad market.
Usually there are two reasons PVC can be widely used. One is the unique properties of PVC which is rainproof, fire-resistant, antistatic and easy to form, and the other is the low investment and high output characteristics of PVC. So, PVC waterproof zipper has waterproof characteristics. It is widely used on many fields, and it is 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 .
