About EPR Self Fusing Tape

We are one of the leading manufacturers and suppliers of highly elastic EPR Self-fusing Tape that is commonly used for jointing and repairing power cables with high voltage rating of up to 69 kilo-volt. It is made up of top-quality ethylene propylene rubber which gives high insulation and waterproofing properties. It is available in various lengths, widths, and thicknesses as per the order placed by our customers. EPR Self-fusing Tape is in high demand due to its compatibility with rubber as well as plastic dielectric cables. The offered tape is capable to withstand temperature within the range of -40 to 100 degrees Celsius.

Electroarc Insulation Tape is an EPR based insulation tape possessing excellent electrical, chemical and physical properties. It maintains a tight insulation built up without any voids giving good electrical stability and resistance to moisture penetration. Compatible with most commonly used Cable Jackets i.e. XLPE, PVC, PILC or Rubber Sheathed Cable.

Features & Benefits:

The tape has the property of cold flow, thereby when applied with 50% overlap, different layers, sticks with each other resulting into formation of void free insulation.
Excellent resistance moisture, contamination and adverse environmental conditions.
Excellent UV stabilized & weather resistant.
High heat dissipation helps to keep the conductor cooler.
Excellent electrical & thermal Provides protection to the conductor material against corrosive elements present in the environment.

FAQ's of EPR Self Fusing Tape:

Q: How do I apply EPR Self Fusing Tape for cable insulation or repair?

A: Start by cleaning the application area, then stretch the tape and wrap it tightly around the cable, overlapping each layer by half its width. The tape will naturally fuse to itself, forming a seamless, durable insulation layer without the need for heat or adhesives.

Q: What benefits does EPR Self Fusing Tape offer compared to regular insulation tapes?

A: This tape offers high dielectric strength, excellent flexibility, and long-term resistance to UV and ozone exposure. Unlike standard adhesive tapes, it bonds to itself on contact for a more robust and waterproof seal, making it ideal for cable splicing, sealing, and emergency repairs.

Q: When should I use EPR Self Fusing Tape instead of other insulation tapes?

A: Use this tape when you need advanced electrical insulation, waterproof sealing, or must insulate cables exposed to weather or high stress. Its high elongation and peeling strength ensure reliable performance in both routine maintenance and emergency situations.

Q: Where can this tape be effectively used?

A: EPR Self Fusing Tape is ideal for insulating and sealing power cables, connectors, and joints both indoors and outdoors. Its weather resistance makes it suitable for exposed locations and harsh environments, including industrial, utility, and residential settings.

Q: What are the recommended storage conditions and shelf life of the tape?

A: Store the tape in a cool, dry place to maintain its properties. When stored properly, it has a shelf life of up to 2 years, ensuring long-term usability and performance.

Q: What is the process for removing the tape after use?

A: Although the tape fuses to itself, it can be cut and peeled away manually when required, leaving minimal residue and making cable maintenance straightforward.

Q: What makes EPR Self Fusing Tape highly conformable and weather-resistant?

A: Its ethylene propylene rubber composition allows it to stretch and adhere to unequal surfaces, while UV and ozone resistance safeguards it against environmental aging, delivering exceptional durability and performance.
