REPERO WTE721EX-0019-07 Self-Vulcanizing Tape 19mm x 7m Black

The REPERO WTE721EX-0019-07 is a high-quality self-vulcanizing (self-fusing) tape designed for electrical insulation, moisture sealing, and cable repair. Made from Ethylene Propylene Rubber (EPR), this tape fuses to itself without adhesive, creating a solid, waterproof, and UV-resistant seal. With a width of 19 mm and length of 7 m, it is ideal for high voltage applications up to 69 kV with proper layering.

Advantages

Self-vulcanizing technology ensures a permanent, non-adhesive bond that resists moisture, UV, and extreme temperatures from -40°C to 90°C. High dielectric strength (>20 kV/mm) and elongation >700% provide reliable insulation and flexibility. RoHS compliant and compatible with solid dielectric cable insulation.

Suitable for

• Electrical insulation and splicing of cables
• Moisture sealing of electrical connections
• Repair of cable jackets and insulation
• High voltage applications (up to 69 kV with layering)
