3M Rubber Mastic Tape 2228 – Self-Fusing Rubber Electrical Insulating & Sealing Tape
Category: Packaging, Tapes & Adhesives
3M Rubber Mastic Tape 2228 is a conformable self-fusing rubber electrical insulating and sealing tape designed for electrical insulating and moisture sealing applications. It consists of an ethylene propylene rubber (EPR) backing coated with an aggressive, temperature-stable mastic adhesive and features a 1.65 mm thick construction for quick application build-up. The tape is designed for use on copper or aluminium conductors rated at 90°C with an emergency overload rating of 130°C, while providing excellent resistance to moisture and ultraviolet exposure for dependable indoor and weather-exposed outdoor applications
Its highly conformable construction allows easy application over irregular surfaces while remaining compatible with solid dielectric cable insulations. The self-fusing design provides reliable electrical insulation and moisture sealing, and the thick construction enables quick build-up and padding over irregular connections. The tape offers excellent adhesion and sealing characteristics with copper, aluminium and power cable jacket materials, making it suitable for cable and wire connections, motor leads, bus bar insulation and other electrical sealing applications specified by the manufacturer.
