3M Scotch 2228 Rubber Mastic Tape
3M Scotch 2228 Rubber Mastic Tape is a go-to sealing and insulating solution in installation accessories and spares because of its outstanding conformability, long-term dielectric properties, and ease of use for on-site repairs. Compared with molded solutions like Raychem GELCAP end seals it is more flexible and lower cost for small repairs or irregular surfaces, and it pairs economically with fastening products such as Ty‑Rap cable ties and grounding connectors for comprehensive field kits.
