There are several effective methods for installing TITAPE® webbings made from TPU (thermoplastic polyurethane) coated polyester. Common techniques include high-frequency (HF) welding, ultrasonic welding, heat sealing, as well as gluing, sewing, and taping.
High-Frequency (HF) and Ultrasonic Welding
HF and ultrasonic welding are generally the most reliable methods for creating strong, durable, and watertight bonds, even in demanding environmental conditions.
- HF welding uses electromagnetic energy to generate heat through molecular friction within the material.
- Ultrasonic welding, by contrast, transfers high-frequency vibrations into the material, creating mechanical friction and heat.
Both methods are suitable for thermoplastic materials. In general, HF welding is preferred for thicker materials and larger bonding areas, while ultrasonic welding is better suited for smaller and more precise joints.
Please note that the optimal welding process — including factors such as power, pressure, temperature, and cooling time — as well as the most suitable coated fabric, must always be evaluated individually for each application.
Heat Sealing (Hot Air Welding)
Heat sealing joins laminates by applying heat and pressure until the material fuses together. This method provides a simple and effective way to melt and bond the layers.
Gluing
Some customers use the adhesive Remda Tip Top SC4000 for bonding applications. However, the suitability of the adhesive should always be tested for each specific use case.
Sewing
When sewing is used, it is essential that all stitching holes are completely covered with an additional sealing tape. The sealing tape must be applied smoothly and without gaps to prevent leakage.
If the stitching holes are not properly sealed, liquids can penetrate the laminate, which may lead to leakage over time.
