3M™ Electrical Tape 1218 is a one mil polyimide backing with acrylic adhesive. It is designed for high temperature applications, in which a solvent resistant backing is required, used on coils, capacitors and wire harnesses.
FEATURES
- 1 mil polyimide backing
- Acrylic adhesive
- Supplied on 3 inch cores
- Widths from 1/4” to 23”
- Longer lengths up to several times normal length, dependent upon width.
APPLICATIONS
- Used for high temperature electrical applications in which a tough, thin insulating material that is solvent-resistant is required for wrapping coils, transformers, capacitors and wire harnesses.
- Used as a cover layer material for many types of flexible printed circuits.
