3M 5413 Polyimide Electrical Tape Amber 5yd 4in 2.7mil

3M 5413 Polyimide Tape for High-Temperature

This 3M 5413 tape uses a polyimide film with a silicone adhesive for electrical insulation in demanding environments. The amber colour provides visual identification on wiring harnesses and circuit boards. It is supplied as a continuous roll measuring five yards in length and four inches wide. The 2.7 mil thickness balances conformability with dielectric strength for general-purpose high-temperature wrapping.

Sustained Thermal Performance from Minus 100

The tape maintains adhesion and dielectric integrity across a continuous operating range from minus 100 degrees F up to 500 degrees F. Unlike general-purpose vinyl tapes that soften or become brittle, the polyimide carrier and silicone adhesive resist thermal cycling without delaminating. This stability supports reliable insulation on components that experience prolonged heat soak or rapid temperature swings during operation.

Voltage Rating Not Rated Limits Direct

The product carries no voltage rating, so it must not be relied upon as primary insulation for energised conductors at hazardous potentials. It suits wrapping, coil banding, and masking where mechanical protection and thermal endurance are the primary requirements. Users must verify that the application stays within the tape's dielectric capabilities through independent testing or relevant equipment standards.
