3M™ Polyimide Film Electrical Tape 1205 Polyimide Film Tape with Acrylic Pressure-Sensitive Adhesive Data Sheet February 2017 Description 3M™ Polyimide Film Electrical Tape 1205 is a 1-mil polyimide film backing with acrylic adhesive. Its acrylic pressure-sensitive adhesive allows it to be used at 311ºF (155ºC), and it is UL 510 Flame Retardant. Like most insulated tapes, from 3M, Tape 1205 is available in standard and custom widths and lengths. The standard length is 36 yards, and can be cut to widths ranging from 1/4” to 23”. Longer lengths up to several times normal length are possible, dependent upon width.--Check with Customer Service for details. Agency Approvals & Self Certifications UL Recognized component listing not to exceed 155°C (311°F), Meets flame retardant requirements of UL510, Product Category OANZ2, and 3M File No. E17385 UL File Number E17385 A and B, Guide OANZ2. Underwriters Laboratories (UL) Recognized products have been evaluated for use as components of end-product equipment that is listed or classified by UL. To achieve Underwriters Laboratories recognition, component construction must meet UL specifications and conditions of acceptability for proper and safe use of the component or product. Product Category OANZ2, File E17385 For RoHS information, please visit www.3M.com/ROHS Applications Specifications 3M 1205 Tape is used for high-temperature electrical applications in which a tough, thin insulating material is required for wrapping coils, transformers, capacitors, wire harnesses, and for anchoring leads / terminal boards. It also is used in printed circuit board assembly as a wave solder masking tape. 3M 1205 Tape is a polyimide film with thermosetting acrylic pressure-sensitive adhesive. The tape shall be coated on one side with pressure-sensitive adhesive, which shall not require heat, moisture or other preparation prior to or subsequent to application. The adhesive coating shall be smooth and uniform and be free of lumps and bare spots. There shall be no separator between adjacent layers of the roll. The tape shall perform at a temperature of -40°F (-40°C) to 311°F (155°C) without substantial loss of tensile or electrical properties 1 of 2 3M 3M™ Polyimide Film Electrical Tape 1205 Typical Properties Not for specifications.
