Scotch 2228 consists of an ethylene propylene rubber (EPR) backing coated with an aggressive, temperature-stable mastic adhesive. The tape is 1.65mm thick for quick application build-up. It is designed for electrical insulating and moisture sealing applications. Scotch 2228 can be used on copper or aluminium 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.

The specimens were thermal cycled in water baths at 25°C and 90°C. The total test time of 336 hours revealed no significant change in insulation resistance. The results exceed requirements listed in UL486D “Standard for Insulated Wire Connectors for Use With Underground Connectors” for insulation resistance (6.0 megohms, section 7.1) and dielectric voltage withstand (2.2kV, 1 minute, section 8.1) Scotch 2228 should be applied in half-lapped layers until desired insulation build up is reached. Stretch the tape to ¾ of its original width during application for good conformability and to obtain a moisture tight seal. Specification The tape shall be 1.65mm thick. The tape must be ethylene propylene rubber based and coated with a rubber mastic pressure sensitive adhesive. The tape must be classified for normal service temperatures up to 90°C with allowable short-term exposure up to 130°C. The tape must be applicable at temperatures of 0°C to 38°C without loss of physical properties. The tape must be classified for use in both indoor and weather exposed outdoor environments. Scotch 2228 should be overwrapped for mechanical protection with two half-lapped layers of Scotch Brand vinyl electrical tape. Shelf Life Scotch 2228 tape has a five year shelf life (from date of manufacture) when stored under the following recommended storage conditions. Store behind present stock in a clean, dry place at a temperature of 70°F (21°C) and 40-50% relative humidity. Good stock rotation is recommended. Availability Scotch 2228 Rubber Splicing Tape is available from your local 3M authorised distributor. The tape must not split or crack when exposed to normal operating temperatures and environments. The tape must be compatible with synthetic cable wire insulations. The tape shall not be corrosive to aluminium or copper conductors.
