KE28 Rubber Mastic Tape


KE28 is a versatile, adaptable rubber tape used for insulating and sealing electrical components. Crafted from ethylene propylene rubber (EPR), it boasts a sturdy backing coated with a potent, thermally stable adhesive.


This tape, measuring 65 mils (1.65 mm) in thickness, enables rapid application buildup. It is meticulously engineered for the purpose of safeguarding against electrical issues and moisture infiltration. Ideal for application on copper or aluminum conductors rated at 90°C, it can handle emergency overload conditions up to 130°C.


Notably, KE28 showcases exceptional resilience to moisture and UV exposure, making it suitable for both indoor usage and outdoor application in various weather conditions.
