Mastic is a very tacky material with extreme elongation properties. Rubber mastic tape combines an ethylene propylene rubber backing with a conformable mastic layer.Rubber Mastic Tape 2228 integrates some of the best qualities of both materials−higher temperature rating, conformability, dielectric strength. It’s one tape that belongs in every toolkit.
Pros and Cons of Butyl Tape


For electrical repairs and insulation, silicone tape is a fantastic choice. It can withstand high temperatures and is an excellent insulator, ensuring safety in electrical applications.

Moreover, 3M HT Insulation Tape is known for its easy application and flexibility. The tape can be easily cut to the desired length and applied to a variety of surfaces, including metals, plastics, and composites. This versatility allows it to be used in diverse applications such as automotive wiring harnesses, electronic devices, and even household repairs. Its conformable nature ensures that it sticks well to uneven surfaces, providing effective insulation and protection.


Butyl rubber tape is also incredibly flexible and easy to apply. It can be cut to size and shaped to fit various contours and surfaces. This adaptability makes it a favorite among DIY enthusiasts and professionals alike. Applying the tape typically requires no special tools; even those with minimal experience can achieve a reliable seal by simply cleaning the surface and pressing the tape into place.
Electrical Applications


Alternatives to electrical tape include heat shrink tubing and wire connectors. Heat shrink tubing is usually used for applications with lower gauge wiring, such as smaller electrical circuits, and wire connectors are used at the ends of stripped wires. Other types of adhesive tape should not be used as a substitute for electrical tape as they will not have the thermal efficiency of a dedicated electrical tape and can therefore be unsafe to use in such situations.
3M also makes an electrical tape made of silicone rubber for applications where Class “H” (180°C/356°F) temperatures are encountered i.e., silicone rubber cables.
