Techy info about the zippers::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. Has excellent resistance to heat (up o 360 degrees F) and cold to 60 degrees F below 0). Melts at 480 degrees F. Resistance to chemicals further extends the use for the Vislon Zipper beyond the scope of conventional metal zippers.
