Drysuit Seam Tape - Supplier

Depending on the material, the stitching position of the drysuit is usually use a heat sealing machine hot melt tape (hot tape) or glue rubber tape (glue tape) for waterproof reinforcement. We use Japan MELCO™, China and homemade products for hot melt tape, and Taiwan Butyltex® and homemade products for glue rubber tape. The hot melt tape and glue rubber tape can be cut into different widths according to different needs, and can also be made into a round or square shape for use when repairing drysuits.

Drysuit Hot Melt Tape (Hot Tape)

Explain: We use a heat sealing machine to weld the hot melt tape to the seam of the drysuit, which has achieved the purpose of waterproofing. This process is called hot tape. We can provide classic hot melt tapes made in Japan, such as MELCO™ T5000, as well as cheaper hot melt tapes made in China.

Note: Different fabrics are suitable for different types of hot melt tape, and the temperature control and feeding speed of the heat sealing machine need to be adjusted. The manual heat pressing effect of the digital temperature control electric iron is also good (for repairing).

Drysuit Glue Rubber Tape (Glue Tape)

Explain: Unlike hot melt tape, the rubber tape itself is not sticky. After processing the sewing thread and rubber tape with auxiliary glue and treatment agent, we use glue to glue the rubber tape to the seam line, which has achieved the purpose of waterproofing. This process is called It is a glue tape.

Note: This process is more complicated, and there are many types of glue and auxiliary agents, but its firmness and sealing are very good. Drysuits used for diving usually use this process to waterproof and strengthen the seams.

Note: Breathable tri-laminate drysuit are not suitable for diving, but because of its light and low-cost characteristics, many brands have launched ultra-lightweight travel drysuit (equipped with inflation valve and exhaust valve) made based on breathable tri-laminate fabric, but it can generally only be used for diving at a depth of no more than 10 meters. In fact, there are also lightweight options for butyl tri-laminate fabric, but the price is more expensive than breathable tri-laminate fabric.

Drysuits Leaking and Maintenance Problems:

All our drysuits are tested for pressure leaks in a test pool before leaving the factory to ensure that the drysuits do not leak when shipped, but the harsh transportation environment (Abnormal collision and squeezing) and incorrect storage (abnormal squeezes) occasionally cause water leaks (rarely found).

Unless drysuits are rarely used, water leakage is practically impossible to avoid. Due to the use environment, strength, habits, matching, cleaning and storage methods and occasions, component life and aging and other factors, many drysuits are used after dozens to hundreds of times, it will happen water leaks.

Leaking does not mean that drysuits can no longer be used, most of the water leakage conditions can be repaired. We provide warranty services (quality problems) and repair services (use problems). Unless the aging material has no repair value, everything else can be repaired.

Under normal circumstances, common simple problems are recommended to customers to repair by themselves (such as small leaks, etc.) to save time and transportation costs. We have optional repair kits when we leave the factory, and various repair kits are also available on the market. If there is a big problem, it is recommended that the customer return to the factory for repair (for example: replacing the waterproof zipper, repairing a large break, etc.).
