Introduction to Waterproof Zipper

Waterproof zipper is a specially designed zipper mainly used in occasions that require waterproof, moisture-proof or sealing functions, such as outdoor clothing, diving suits, tents, waterproof bags, etc. Unlike ordinary zippers, waterproof zippers effectively prevent moisture infiltration and ensure the dryness of internal items through material, structure, and process optimization.

Characteristics of Waterproof Zipper
Waterproof materials: PVC (polyvinyl chloride), TPU (thermoplastic polyurethane) or specially coated nylon are usually used as zipper teeth and base materials, which have excellent waterproof and corrosion resistance.
Sealing design: The teeth of the waterproof zipper are tightly interlocked, and a waterproof rubber strip or hot pressed sealing layer is added to the back of the zipper to further prevent moisture from seeping in.
Durability: The waterproof zipper has been specially treated to have UV resistance, wear resistance, and low temperature resistance, making it suitable for harsh environments.
Smooth opening and closing: Some high-end waterproof zippers adopt self-lubricating design, which can be smoothly pulled even in humid or low-temperature environments.
Types and Applications
PVC waterproof zipper: Low cost, commonly used in raincoats and ordinary waterproof bags.
TPU waterproof zipper: good elasticity, environmentally friendly, suitable for high-end outdoor equipment.
Diving zipper: completely sealed, used in professional fields such as diving suits and dry diving suits.
Purchase and maintenance
When making a purchase, it is important to pay attention to the waterproof rating (such as IPX standard) and the applicable environment. After daily use, the zipper gap should be cleaned to avoid prolonged exposure to sunlight or corrosive substances, in order to extend its lifespan.

Waterproof zippers, with their reliable sealing performance, have become essential accessories for outdoor sports, navigation, medical and other industries, providing users with more comprehensive protection.
