1. Performance requirements of Plastic Zippers
(1) Good wear resistance to ensure the life of the Long Chain Continuous Plastic Zipper.
(2) Low coefficient of friction and excellent self-lubricating properties to ensure free sliding.
(3) High creep resistance and fatigue strength to ensure a firm fit.
(4) High dimensional accuracy to ensure a precise fit.
(5) Good heat resistance to ensure hot water and water vapour washing.
(6) Good corrosion resistance to suit the washing environment of various detergents.
2. Material selection for Colorful Plastic Zipper
(1) Nylon 66
PA66 is the earliest Plastic Zipper, still occupies the small Zipper market, PA66 is often extrusion stretching method forming processing, first PA66 stretching into silk, and then by winding forming for Zipper products, PA66 molding processing efficiency, and has excellent creep resistance, fatigue resistance, wear resistance and low friction coefficient, self-lubricating properties better than POM.

(2) Polyformaldehyde POM
POM's molding method is mainly injection molding, with the advantages of high precision with the size, and can be molded large size Zipper, in the large size Zipper market accounted for the main mainstream, POM's friction coefficient and wear amount is small, the friction coefficient is PA66 1/3, suitable for long-term sliding parts, fatigue resistance is the best Plastic, wear resistance is PA66 as much as three times.

(3) Glass fibre reinforced PET
GFPET can be injection moulded and extruded to produce Zippers, GFPET creep resistance, wear resistance and friction are better than PA66 and POM, fatigue resistance and POM equivalent, good low temperature resistance, suitable for use in cold areas, the price is 50% lower than POM, 160% lower than PA66. The disadvantage is that the self-lubrication is lower than PA66 and POM.
