MTE Solutions Polyimide Kapton Tape 1 Mil - 72 Yards - Variety of Sizes (2.5 Mil Total)
MTE Solutions Polyimide Kapton Tape, 1 Mil Backing, Silicone Adhesive, Amber, 72 Yards — Variety of Widths
MTE Solutions polyimide Kapton® tape is made from DuPont™ Kapton® HN polyimide film with a silicone adhesive backing. The 1 mil film provides outstanding thermal resistance, excellent electrical insulation, and high dielectric strength — rated for continuous use up to 260°C (500°F) with short-term peak performance to 400°C (752°F). The silicone adhesive bonds securely during high-temperature processing and removes cleanly without adhesive residue. This 72-yard roll format offers double the length of the standard 36-yard roll, making it the preferred choice for high-volume SMT assembly, PCB masking, and production environments where roll changes slow throughput. Available in 1/4", 1/2", 5/8", and 3/4" widths.
Sold individually by width (select size above). 72 yards/roll.

Frequently Asked Questions
Why choose the 72-yard roll over the 36-yard roll?
The 72-yard roll is designed for high-volume production environments where minimizing roll changes improves throughput and reduces downtime. If your operation uses polyimide tape continuously in SMT assembly, wave soldering, or conformal coating masking, the 72-yard roll cuts your roll change frequency in half compared to the standard 36-yard roll. The 36-yard roll is the better choice for lower-volume use, prototyping, or when you need a wider selection of widths (the 36-yard version is available in 11 widths vs. 4 widths for the 72-yard roll).
What is Kapton tape used for?
Kapton® polyimide tape is used in any application requiring electrical insulation, high-temperature masking, or mechanical protection at temperatures that would destroy standard tapes. Common applications include masking PCBs during wave and reflow soldering, insulating transformer windings and motor coils, bundling and protecting wire harnesses, masking surfaces during powder coating and paint baking, and protecting components during conformal coating. The combination of high thermal stability, electrical insulation, and clean silicone adhesive removal makes it the standard tape for electronics manufacturing.
Will the silicone adhesive leave residue after removal?
No. The silicone adhesive is formulated for clean removal after high-temperature processing. It bonds securely during soldering, powder coating, or other heat processes and releases cleanly without leaving adhesive residue on PCB surfaces, components, or metal parts — even after multiple reflow cycles.
Is this tape compatible with conformal coating processes?
Yes. MTE Solutions polyimide tape is chemically resistant to most conformal coating materials including acrylic, urethane, silicone, and epoxy coatings. It is widely used to mask connectors, test points, and other areas that must remain uncoated during the conformal coating process. The silicone adhesive provides a clean seal at the tape edge to prevent coating bleed-under.
