Long-form articles for engineers specifying a sealed opening. Each one is the manufacturer’s published technical copy, restructured so the tables and headings are readable on the web rather than locked inside a PDF.
Choose an airtight waterproof zipper in four steps: waterproof rating, size, material and custom specification. Includes the published IPX6–IPX8, #5/#8/#10 and material comparisons.
Read the articleAirtight, watertight and waterproof are three different sealing levels. This guide compares their definitions, ratings, structure and typical uses — and the one question that tells you which you need.
Read the articleWhat IPX6, IPX7 and IPX8 actually mean, with the IEC 60529 test conditions behind each rating and the limitations of using IPX alone to specify a sealed zipper.
Read the articleWhy silicone rubber is used for drysuit envelope zippers, how salt water and deep-sea pressure affect the seal, and what to test before specifying an IPX8 drysuit closure.
Read the articleHow TPU airtight zippers are constructed and joined to a host material — high-frequency welding, sewing with tape, and bonding — and what each process means for seal integrity.
Read the articleWhat an inflatable closure has to do — hold air pressure, survive folding and resist abrasion — and how airtight zipper specification follows from that.
Read the articleWhat to compare when sourcing airtight waterproof zippers — published test values, material capability, process range, customisation envelope and documentation.
Read the articleA complete procurement checklist for custom airtight zippers: the parameters to supply, the sample validation steps, and the acceptance criteria to agree before mass production.
Read the articleThese articles are also published as the reference set in the technical guides section, which is the canonical home for this content.
Send the drawing, the host material and the rating you are working to. We will come back with the series, the assembly process and the test conditions to agree.
