^{Polyimide Film 1218 Acrylic Adhesive 聚酸亞胺薄膜膠帶丙烯酸膠黏劑 無鹵 Non-Halogenated}

3M 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. 3M Tape 1218 is available in standard and custom widths and lengths. Standard length is 36 yards.
• 1 mil polyimide backing
• Acrylic adhesive
• Supplied on 3 inch cores

3M Tape 1218 is 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. It is also used as a cover layer material for many types of flexible printed circuits.
