This is a conformable self-fusing rubber electrical insulating and sealing tape. It consists of Ethylene Propylene Rubber (EPR) backing coated with a strong, temperature-stable mastic adhesive.
These rolls and pads are self-fusing, rubber-based thin insulating mastic compounds laminated to a flexible, all-weather grade PVC backing and are designed for moisture sealing of electrical connections up to 600 Volts.
