Common questions
Questions buyers ask about this product
How do I choose between #5, #8 and #10 airtight waterproof zippers?
#5 suits lightweight and flexible products, #8 suits medium-to-high strength waterproof equipment, and #10 suits heavy-duty, pressure-resistant and industrial sealing projects. The plastic, nylon woven, self-healing and circular ranges address military equipment, waterproof equipment, sealed bags and luggage, and protective suits. When selecting, supply the use case, opening length, tape width, host material, water or air pressure, opening frequency and target waterproof rating.
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. Plastic teeth with a sealing layer suit openings that need higher strength.
