High quality zipper. YKK use plastics with high strength and good UV resistance for all zippers and their components.

Polyester carrier tape with water repellency treatment. Sliders, teeth and endcaps are made of "POM" (Delrin) plastics. POM feature high strength, hard- and stiffness in a wide temperature range. POM has a high abrasion resistance, low friction, high dimensional stability under heat and good sliding properties.

We recommend POM zippers in salt water environment to prevent corrosion.
