Product Description
3M™ Polyimide Film Electrical Tape 92 with Silicone Adhesive is an amber electrical tape constructed with a polyimide film backing and a non-corrosive, thermosetting silicone pressure-sensitive adhesive. The 2.75 mil (0.070 mm) tape is designed for continuous operation at temperatures not exceeding 180°C (356°F) per its UL listing. It is commonly used for electrical insulation, component wrapping, lead anchoring, and solder masking during printed circuit board assembly.
Key features
- High-temperature electrical tape: Designed for continuous operation at temperatures not exceeding 180°C (356°F) per its UL listing.
- Polyimide film construction: Combines a nominal 1 mil (0.025 mm) polyimide backing with a thermosetting silicone pressure-sensitive adhesive.
- Electrical insulation performance: Provides a minimum dielectric breakdown of 6,000 V and minimum insulation resistance of 1 × 1012 Ω.
- Non-corrosive adhesive: Delivers an electrolytic corrosion factor of 1.0, where 1.0 indicates no corrosion observed under 3M Test Method ETM-54001.
- Pressure-sensitive application: Requires no heat, moisture, or other preparation to achieve application.
Applications / Suitable for
- Wrapping coils, capacitors, wire harnesses, and transformers
- Anchoring electrical leads
- Solder masking during printed circuit board assembly

General Properties
Adhesive Layer
thermosetting silicone
A layer that is applied to one surface or both to bind items together and resist their separation
Color
amber
The color
Film Thickness
0.025 mm
Film thickness is the thickness of a backing film without taking into account any coatings or adhesive layers. It is measured in micron and the conversion factor to mil is 0.039.
Total Thickness
190 μm
Total thickness is taking into account all the films, coatings, adhesives, release liners and special layers and is the maximum thickness of a film or tape.
Mechanical Properties
Adhesion Strength
18 Oz/in
Adhesion is the bond strength measurement of a coating to a substrate. When an adhesive is bonded to an item or surface, numerous physical, mechanical and chemical forces come into play, which may have an effect on each other.
Elongation
40 %
Elongation is the process of lengthening something.
It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks.
It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
Electrical Properties
Breakdown Voltage
6,000 V
Breakdown voltage is the minimum voltage necessary to force an insulator to conduct some amount of electricity.
It is the point at which a material ceases to be an insulator and becomes a resistor that conducts electricity at some proportion of the total current.
After dielectric breakdown, the material may or may not behave as an insulator any more because of the molecular structure alteration. The current flow tend to create a localised puncture that totally alters the dielectric properties of the material.
This electrical property is thickness dependent and is the maximum amount of voltage that a dielectric material can withstand before breaking down. The breakdown voltage is calculated by multiplying the dielectric strength of the material times the thickness of the film.
