REPERO 722E Super Bond Cinta autovulcanizante 25mm x 3m Negro

The REPERO 722E Super Bond Self-Vulcanizing Tape is a high-performance electrical insulation tape designed for professional use. Made from ethylene propylene rubber (EPR), this tape fuses to itself upon application, creating a homogeneous, moisture-proof, and airtight seal. Ideal for low and medium voltage cable insulation, splicing, and repair, it offers excellent dielectric strength, UV resistance, and a wide operating temperature range.

Advantages

Self-fusing technology eliminates the need for adhesive, ensuring a secure bond that does not unravel over time. The tape provides outstanding electrical insulation up to 69 kV, along with protection against water, chemicals, and corrosion. Its high elongation (over 700%) allows for conformability to irregular surfaces, while the UV-resistant formulation ensures long-lasting performance in outdoor environments.

Suitable for

• Electrical insulation of low and medium voltage cables
• Sealing and waterproofing cable joints and terminations
• Corrosion protection for metal conductors
• Repair of damaged cable sheaths
• Overhead and underground cable applications
