Self Vulcanizing Tape

The vulcanisation process is a chemical reaction in which heat turns a malleable rubber compound into flexible rubber. Although more time-consuming than a simple repair, it is a more durable, safer and more flexible solution. And in the case of vulcanising tape, we are talking about a bonding technique that vulcanises without the application of heat. Self-vulcanising tape is most typically used to protect connections in telecommunications data transmission systems. It is an extremely versatile material, an excellent electrical insulator, with a high resistance to moisture and chemicals, weathering and UV rays. Its properties, when correctly applied, provide watertight connections in damp locations over a wide range of temperatures. Read more...

What is vulcanising tape used for?

It can be used primarily to bond low voltage and cable TV and telephone cables, but its uses can be very diverse. The main applications are:

  • In telecommunication and power systems, it provides basic protection of connections.
  • It can be used to terminate wires and cables, to protect splices against corrosion and to protect the splice.
  • It is suitable for insulating, covering and protecting electrical cables.
  • It can also be used for coaxial, CCTV, UTP and FTP cable connections.
  • It can also be used for waterproof covering of cables where they need to be water and moisture resistant.
  • It can also be used to seal joints in PVC pipes, to cover the pipes and to protect them against corrosion.
  • Also perfect for repairing cracked pipes.

The tape does not react with the protected surface and does not leave any traces. As the tape can therefore be cleanly removed from most surfaces, it is also an ideal choice for temporary repairs.

How to use vulcanising tape?

The first, and most important thing to do is to ensure that the conditions required for the tape to be effective are met. The surface to be taped must be clean and dry. Free from any dust, grease, oil or other petroleum derivatives. The temperature in the area of application must be above 0 degrees Celsius. Once this is done, the tape is wrapped around the object to be vulcanised without the plastic separator between the sheets.


Vulcanising tape is a very flexible material and can be stretched to the point where it is about two-thirds as wide. The tape must be stretched properly, which is very important to achieve the self-vulcanising effect. When applying the tape, note that the self-vulcanisation process will be triggered by the contact of the tapes with each other. Therefore, when winding successive layers, always ensure that there is at least 50% overlap between them. This will guarantee a tight adhesion of the tape to the object and between its layers. After use, fold back the end of the tape to prevent the risk of it sticking to the roll under pressure, which would make it difficult to unwind later.


DND offers a range of quality self-vulcanising tapes in five and ten metre lengths for insulating antenna and cable connectors, moisture protection, sealing and electrical insulation. Our products come with a two-year warranty period, and as a related service we can also provide custom cable production and connector assembly, whether you need 1 or 1000 pieces, using our vulcanising tapes.
