Rubber Mastic Tape - 1.65mm thick- 3M 2228
Scotch 2228 (3M Rubber Mastic Tape)
is a conformable self-fusing rubber electrical insulating and sealing tape. Scotch 2228 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. Scotch 2228 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.
Applications for 3M 2228 Rubber Mastic tape;
Primary electrical insulation for cable and wire connections rated up to 1000 volts
Electrical insulation and vibration padding for motor leads rated up to 1000 volts
Primary electrical insulation for bus bar connections rated up to 35 kv (3M drawing 2047B–106)
Padding for irregular shaped bus bar bolted connections
Moisture seal for cable and wire connections
Moisture seal for service drops
Moisture seal for ground wire and rod connections
Jacket seal on power cable applications
Description
The 3M Scotch 2228 Rubber Mastic Tape is a conformable self-fusing electrical insulating and sealing tape designed for moisture protection, insulation, and padding of electrical connections.
