Nylon waterproof zipper

The waterproof zipper is a branch of nylon zipper, which is a nylon zipper that has undergone certain special treatments. Commonly used special methods include pasting PVC film, pasting TPU film, soaking in waterproofing agent, coating waterproof zippers, etc.

The main material used for waterproof zippers with PVC film is PVC, and the main component is polyvinyl chloride. TPU film is a film made of TPU granules through a special process. It inherits the excellent physical properties of TPU and has an extremely wide range of applications. Because TPU overcomes many of the shortcomings of PVC, TPU waterproof zippers are also superior in performance to PVC waterproof zippers. The characteristics of the coated waterproof zipper are that it does not fall off, does not turn white, does not become brittle, is resistant to low temperatures of minus 70 degrees Celsius, is environmentally friendly, soft, and has good waterproof properties.
