The aging behavior of TPU-coated, waterproof zippers has been a significant focus of TIZIP’s product development for decades.
It has been mostly analyzed that TPU coating material failure, characterized by swelling, cracks, or delamination, is caused by aging (moisture, temperature, microorganisms, etc.), known as hydrolytic degradation processes. Despite various handling precautions contributing significantly to minimizing hydrolytic degradation, TIZIP has now developed a optimized TPU coating material that eliminates the typical aging behavior of TPU-coated zippers in the long term.
Especially in the watersports & diving sector, where waterproof zippers are exposed to constant moisture, the new & unique hydrolysis protection represents a significant advantage compared to conventional, short-lived products.
