Water-Resistant and Waterproof Zippers for Cloth and Outdoor Applications

Most high-quality outdoor jackets and backpacks utilize a "reverse coil" nylon zipper construction.
Physical Barrier: This design conceals the zipper teeth beneath a coating, creating a smooth, straight line when the zipper is closed.
Protective Performance: The flat surface effectively blocks rain splashes and prevents fine sand or dust from entering the gaps between the teeth, extending the zipper's lifespan in harsh environments.

Why is TPU the preferred material?
Low-Temperature Flexibility: It ensures the coating does not crack due to cold, making it ideal for polar or high-altitude environments.
Abrasion Resistance: It withstands frequent sliding friction, maintaining the integrity of the coating and its long-lasting waterproof performance.
Matte or Glossy Options: Available in different finishes to suit various outdoor design styles—from the matte, textured look seen on jackets to the vibrant, glossy appearance often found on backpacks.
