Common questions
Questions buyers ask about this product
How do I choose between TPU, PEVA, silicone rubber and nylon woven materials?
TPU suits most airtight waterproof projects. PEVA suits lightweight and economy waterproof products. Silicone rubber suits wide temperature ranges and high-end sealing. Nylon woven with TPU suits garments and flexible fabrics. Resin teeth with a sealing layer suit openings that need higher strength.

YILON currently covers 9 main product ranges: #10 resin airtight zipper, #5 resin airtight zipper, self-healing airtight zipper, PEVA airtight zipper, #5 nylon woven waterproof zipper, #8 nylon woven waterproof zipper, high-speed roller door zipper, circular airtight zipper and drysuit envelope. The #10 resin, #5 resin, self-healing, high-speed roller door and circular ranges are published with 3,000+ cycle durability.
What is an airtight waterproof zipper, and what sealing problems does YILON solve?
An airtight waterproof zipper stops water, air and moisture entering or escaping through an opening. It suits products that need an openable sealed port: military equipment, waterproof equipment, sealed bags and luggage, protective suits, diving gear, inflatable products and industrial high-speed doors. YILON can customise length from 5 cm to 100 m, plus size, tape width, colour, slider, opening style, material and testing requirements.
What do the IPX6, IPX7 and IPX8 waterproof ratings mean?
IPX6 means protection against powerful water jets, IPX7 means protection against temporary immersion, and IPX8 means continuous immersion under agreed conditions. When selecting, define the test depth, pressure, duration, mounting method, end structure and whether the zipper must be opened and closed repeatedly.
