Why High-Strength TPU Coated Zippers Are Essential for Industrial Sealing

In the world of industrial manufacturing, it’s often the smallest components that carry the biggest responsibilities.

If you’ve ever designed a life-saving suit, engineered a military-grade container, or sourced materials for inflatable structures, you know this truth well: when sealing fails, everything fails.

And that’s where high-strength TPU coated zippers come in.

From life rafts to hazmat suits and airlock chambers, the zipper is no longer just a closure—it's a critical sealing solution. At KINZIP, we’ve spent nearly two decades helping OEMs and manufacturers across sectors meet the most demanding airtight and waterproof standards. In this article, we’ll walk you through what makes these zippers so effective—and why they’re essential to your design and product integrity.

What Are High-Strength TPU Coated Zippers?

High-strength TPU coated zippers are engineered sealing solutions that combine durable zipper hardware with a thermoplastic polyurethane (TPU) coating. These zippers are specially designed for airtight and waterproof applications across industrial, marine, military, and environmental protection industries.

✅ What Does TPU Coating Add to a Zipper?

TPU (thermoplastic polyurethane) is known for its:

·         High elasticity

·         Abrasion resistance

·         Chemical and water resistance

·         Flexibility across a wide temperature range

When applied as a coating, TPU creates a flexible but sealed surface that prevents air, water, fuel, and fine particulate matter from penetrating the zipper structure.
