Red Anti-Tracking Sealing Mastic Tape is designed for high-voltage and medium-voltage cable insulation and sealing. Provides excellent anti-tracking, UV resistance, and weatherproofing in outdoor environments. Used for cable joint protection, termination sealing, and moisture barrier applications. The tape is non-tracking, flame retardant, and self-bonding for efficient performance. Supplied between two silicone release liners for clean, easy handling and application. Ideal for substations, power utilities, switchgear, and industrial electrical systems.
