Scotch 2228 Rubber Mastic Tape , HY-2228

Scotch 2228 Rubber Mastic Tape , HY-2228

Scotch 2228 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 electrically 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.

Tape Features:

* Conformable for application over irregular surfaces

* Compatible with solid dielectric cable insulations

* Self–fusing tape

* Flexible over the wide temperature range

* Excellent weather and moisture resistance

* Excellent adhesion and sealing characteristics with copper, aluminum and power cable jacket materials.

* Thick construction allows quick application build–up and padding over irregular connections
