YKK Vislon® Separating Zippers are extremely strong and lightweight and differ from conventional zippers, because the "teeth" are made from Delrin® and the tape is polyester. Because of the unique properties of the Vislon Zipper, it has a wide variety of industrial, consumer and military applications where environmental conditions reduce the effectiveness of metal zippers.
The Vislon Zipper is corrosion resistant. The zipper is self-lubricating and operates smoothly despite mud, sand etc. The color is an integral part of the molding material, creating a finish that does not rub off, peel or chip.
The Vislon Zipper has excellent resistance to heat (up to 360° F) and to cold (to 60° F below zero),and melts at 480° F, which is 150° F higher than normal laundry temperature. Resistance to chemicals further extends the use for the Vislon Zipper beyond the scope of conventional metal zippers.
