High-Temperature Polyimide Tape

This 3M 5419 electrical tape uses a polyimide film backing with a silicone adhesive. It is gold in colour and supplied as a continuous single-sided roll measuring 36 yards long by one-quarter inch wide. The tape is designed for applications that demand stable performance across extreme temperatures.

Extreme-Temperature Insulation

Engineers and technicians working in environments from minus 100 to 500 degrees Fahrenheit will find this tape suitable for masking, wrapping or insulating tasks. It is not intended for users who require a voltage-rated electrical insulation product.

Thin Profile With Wide Thermal Range

At 2.7 mil thick the tape conforms to irregular surfaces while maintaining integrity across the full stated temperature span. It runs out when a job calls for a dielectric strength rating or a wider roll than the quarter-inch width provided.

Questions about this item

Does the 3M 5419 tape need a specific surface or primer to adhere properly?

The silicone adhesive bonds to clean, dry surfaces without primer. It is designed for high-temperature polyimide film applications and adheres directly to metals, plastics and insulation materials when applied with firm pressure.

Can the 5419 gold tape be layered over older rubber-based electrical tape without degrading?

Yes, the polyimide film and silicone adhesive remain stable from -100 °F to 500 °F, so they will not melt or react with legacy rubber tapes. Overlap wraps stay intact through thermal cycling.

How can I verify the 2.7 mil thickness is consistent across the 36-yard roll after installation?

Measure a wrapped section with a calibrated micrometer at several points; readings should centre on 2.7 mil. Uniform thickness confirms the roll was slit and wound to specification.
