2228 Rubber Mastic Tape

  • DW-2228

Product Description  


 


     2228 is a conformable self–fusing rubber electrical insulating and sealing tape. 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.

     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.
