Description. Rubber mastic tape is a conformable self–fusing rubber electrical insulating and sealing tape. TC-T228 consists of an ethylene propylene rubber (EPR) backing coated with an aggressive, temperature–stable mastic adhesive. The tape is made 65 mils (1,65 mm) thick for quick application build–up. It is designed for electrical insulating and moisture sealing applications. TC-T228 can be used on copper or aluminum conductors rated at 90°C, with an emergency overload rating of 130°C. It offers excellent resistance to moisture and ultraviolet exposure and is intended for both indoor and weather exposed outdoor applications.

			Application. • Primary electrical insulation and moisture sealing in splices and terminations of solid dielectric power cable up to 2kV. • Insulating and moisture sealing of telecommunication cable connectors in base station, antenna and aerial feeders. • Bus bar insulation and corrosion protection. • Cable jacketing. • Other moisture sealing applications.
