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 adhesiv e allows it to be used at
311ºF (155ºC), and it is UL 510 Flame Retardant. Like most in sulated tapes,
from 3M, Tape 1205 is available in standard an d 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 lengt h are possible, dependent
upon width.--Check with Customer Service for details.

Applications
3M 1205 Tape is used for high-tempe ra t ure electrical applications in which a
tough, thin insulating material is require d for wrapping coils, transformers,
capacitors, wire harnesses, and for anchoring le ads / terminal boards. It also is
used in printed circuit board assembly as a wave solder masking tape.
Specifications 3M 1205 Tape is a polyimide film with thermosetting a crylic p re s sure-sensitive
adhesive.
The tape shall be coated on one side with pressure-sensitive adhesi ve, 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 sh all 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 propertie s
