After three years of intensive development and innovation, TIZIP is proud to introduce the next evolution in zipper technology: the all-new MasterSeal #6 Zipper. Engineered for superior performance, the MasterSeal #6 sets new benchmarks in sealing capability, durability, and user convenience:
A Milestone in Zipper Technology
The MasterSeal #6 represents the culmination of extensive research, featuring re-engineered materials, precision-crafted teeth, and refined slider geometries. This meticulous attention to detail delivers a zipper that exceeds expectations in both performance and reliability. While the previous MasterSeal #6 model was already regarded as an industry leader, the advancements in this new iteration reinforce TIZIP’s commitment to continuous innovation and uncompromising quality.
Stay tuned for the official launch date and discover how the MasterSeal #6 can elevate your products to new levels of quality and performance.
Based on the outstanding durability results of the MasterSeal #10 with hydrolysis-protected material, this enhanced material has now been introduced for the SuperSeal as well.
Since the SuperSeal is TPU-coated only on the front side, it is even more critical to eliminate aging effects, especially when the textile backside may not dried after use. As with the MasterSeal, the hydrolysis-protected SuperSeal material can be welded to TPU-coated fabrics. However, PVC is not chemically compatible for direct welding with the hydrolysis-protected zipper. In such cases, PVC must be glued to the hydrolysis-protected zipper material, or alternatively, an intermediate TPU layer can be used for the welding process.
The hydrolysis protection represents a major milestone in advancing the durability and operational performance of TIZIP’s waterproof and airtight zippers.
We would like to inform you that our factory will be closed from December 23th to January 6th for public holiday.
Orders and inquiries received during this time will be attended to after January 7th. Therefore, we would like to encourage you to place your orders for your next waterproof & airtight projects in good time, so we can match your needs with the upcoming holiday season.
Thank you & stay safe!
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 MasterSeal #10 hydrolysis protection represents a significant advantage compared to conventional, short-lived products.
As a running change, the material of the Q-Strap has been optimized in order to further improve the overall performance and quality starting March 13, 2024. The new Q-Strap tape is covered also on the edges avoiding fibers sticking out and provides an adjusted shore hardness and length. Due to the improved material and geometry of the Q-Strap, the position has been slightly adaped from 82,5 mm to to 100 mm.
Reliable products with an outstanding quality level are the key priorities of our TIZIP brand. That’s why we are constantly working on innovative ideas and technical improvements to further enhance the already outstanding quality and durability level of our waterproof and airtight premium TIZIP zippers – 100% made in Germany.
Unfortunately, TIZIP has learned that products falsely claiming to be made by TIZIP or with imitation TIZIP labels are currently being distributed in many areas around the world. Counterfeit products fall short of TIZIP‘s quality standards, and could possibly cause a customer’s product to malfunction as well as cause serious safety issues. Be advised that TIZIP is not responsible for any malfunction or damages that may occur as a result of the use of counterfeit products and that products purchased outside of TIZIP’s authorized or trusted sales channels are not warranted by TIZIP or supported in any way.
We therefore urge that, in order to avoid purchasing counterfeit products, customers only purchase genuine TIZIP products directly from TIZIP’s headquarter in Germany, through TIZIP’s authorized distributors or trusted sources.
If you are unsure whether your next purchase order consists of genuine TIZIP zippers, please have also a deeper lock at the characteristic trademarks of TIZIP zippers listed on our website.
Waterproof zippers play a vital role in outdoor gear, marine equipment, and other applications where moisture protection is paramount. To perform effectively, a quality waterproof zipper must be airtight, resistant to water, and capable of withstanding exposure to salt and harsh chemicals that can cause material degradation.
Selecting the right waterproof zipper involves balancing factors such as durability, ease of use, and cost. While some zippers may come at a higher price point, they often provide enhanced longevity and superior performance in extreme conditions. The specific demands of your project or activity—whether for recreational or professional use—should guide your choice, as different scenarios may call for varying levels of protection and functionality.
For those facing the most rigorous requirements and heavy-duty professional use, an innovative high-performance solution has arrived:
World’s first 1.0 bar waterproof polymer zipper – the new heavyweight.
Introducing new products to the market often comes with significant challenges. After over five years of dedicated research and development, TIZIP has achieved a remarkable breakthrough.

Durability is one of the key priorities for the TIZIP Brand and TIZIP’s premium waterproof & airtight zippers. That’s why we are constantly investigating innovative ideas and technical improvements to achieve an outstanding level of quality.
