3M Heat-Resistant Tape for Electronics and Industrial Machinery

Heat-resistant 3M tape is chosen by continuous working temperature: Temflex 160 up to 80°C, Scotch 33+, 35 and Super 88 up to 105°C, Scotch 27 glass cloth up to 130°C continuous, and polyimide Tape 92 up to 180°C. For motors and transformers, glass cloth is a better fit. For electronics and soldering, polyimide is more common.

Key Takeaways

• Continuous working temperature is the main deciding factor. Vinyl tape generally goes up to 80–105°C, glass cloth up to 130°C and polyimide up to 180°C, according to 3M.
• For motors, transformers and coils: 3M rates Scotch 27 glass cloth for continuous use at Class B (130°C), with a 600 V dry rating.
• For circuit boards and soldering: 3M Polyimide Film Electrical Tape 92 is rated 0–180°C and used as wave-solder masking.
• For cables and general splices: vinyl such as Scotch 33+, 35, Super 88 and Temflex 160 is enough for lower temperatures.
• Check the temperature and voltage ratings together. A heat-resistant tape is not necessarily suitable for the voltage you use.
• The SinarCS catalog (October 28, 2026) lists Scotch 27, Scotch and Temflex vinyl, and Scotch 23. I did not find polyimide tape in that catalog.

Introduction

In electric motors, transformers, panels and electronic devices, heat is an everyday reality. The wrong tape can soften, lose its adhesion or fail to insulate when the temperature climbs. So choosing heat-resistant tape is not just a matter of brand. It comes down to temperature figures, voltage and material type.

This article answers the core question: which 3M tape is heat resistant for electronic components and industrial machinery, and how do you choose it? We compare tape types by 3M's temperature ratings, explain when to use glass cloth or polyimide, and map out the products available at PT Sinar Cemerlang Semesta (SinarCS).

Temperature specifications refer to 3M's product pages and data sheets. SinarCS catalog entries and prices were taken from sinarcs.com as of October 2026.

What Is Heat-Resistant Tape?

Heat-resistant tape is an adhesive tape that keeps its insulating properties, strength and adhesion at high working temperatures. Two terms need to be told apart:

• Continuous temperature: the temperature the tape can withstand in continuous use.
• Short-term temperature: the temperature it can withstand briefly, usually higher than the continuous temperature.

Always use the continuous temperature as your main reference, not the short-term one. For example, 3M's data sheet for Scotch 27 lists a continuous rating of 130°C and a short-term rating of 160°C.

Comparing 3M Tape by Heat Resistance

Note: temperature ranges can be stated differently across pages. For example, the Super 33+ data sheet cites a UL 510 rating at 80°C alongside use up to 105°C. Read the product data sheet to confirm your operating conditions.

Scotch 27: Glass Cloth Tape for Machines and Coils

3M's official product page describes Scotch 27 as a 7 mil woven glass cloth tape with a thermosetting rubber pressure-sensitive adhesive, designed for 600 V dry applications that need high mechanical strength and high temperature resistance. 3M lists the product as UL Recognized at 130°C and suited to coil covers, anchoring, banding, and core, layer and crossover insulation.

3M's data sheet explains the advantage of the cloth material:

"The glass will not shrink, rot or burn"

- 3M, Scotch 27 Glass Cloth Electrical Tape data sheet

That is why Scotch 27 is commonly used on motor windings, transformers and components that run at high temperatures.

Note the Data Discrepancy on the SinarCS Page

SinarCS sells Scotch 27 at Rp139,000 in the catalog checked. However, the product's older description on the SinarCS site lists a maximum temperature of 80°C, which differs from 3M's continuous rating of 130°C. Because temperature data determines safety, ask SinarCS for confirmation and the official data sheet before ordering.

Polyimide Tape for Electronic Components

For circuit boards (PCBs) and soldering, polyimide is often chosen because it withstands higher heat and is thin. 3M Polyimide Film Electrical Tape 92 is rated for 0–180°C, is flame retardant, and is used as wave-solder masking in PCB assembly. 3M's page states:

"Polyimide backing provides exceptional heat resistance"

- 3M, Polyimide Film Electrical Tape 92 product page

The tape is also designed for thick insulation on coils, harnesses and capacitors. However, polyimide tape does not appear in the SinarCS Industrial Tape category I checked. If you need it, ask SinarCS directly about availability.

Recommendations by Application

This table is a general guide. The final choice should follow the real working temperature, voltage and the product data sheet.

How to Choose the Right Heat-Resistant Tape

1. Measure or estimate the continuous working temperature at the point of installation, not the room temperature.
2. Leave a safety margin. Choose tape whose continuous temperature rating is above the maximum working temperature. The size of the margin follows your company's technical standards.
3. Check the voltage rating. The tapes discussed above are rated up to 600 V. Higher voltages need special products and methods.
4. Pick the material to suit the function. Glass cloth for mechanical strength and heat; polyimide for heat and thinness; vinyl for general insulation.
5. Consider the environment. Is it dry, damp, or exposed to oil and solvents?
6. Check certifications. Look for UL, CSA or other standards information on the data sheet.
7. Make sure it is genuine. Buy from a distributor you can verify.

Installation Tips for Hot Areas

• Switch off the power source before working.
• Clean and dry the surface of dust, oil and moisture.
• Wrap with a partial overlap so the layers seal tightly.
• Press the final layer down firmly so the pressure-sensitive adhesive bonds.
• Do not use vinyl tape on surfaces whose temperature exceeds its rating.
• For critical installations, bring in a competent technician and follow the manufacturer's instructions.

Common Mistakes When Choosing Heat-Resistant Tape

• Looking only at short-term temperature, not continuous temperature.
• Using vinyl tape near high heat sources such as windings or exhausts.
• Ignoring voltage. Heat resistant does not mean suitable for any voltage.
• Not reading the data sheet, so the temperature figure in a seller's description is taken on trust.
• Choosing tape that is too thick for small electronic components.

FAQ: Questions About Heat-Resistant 3M Tape

Which 3M tape is heat resistant?

According to 3M, Scotch 27 glass cloth is rated 130°C continuous and polyimide Tape 92 up to 180°C. Vinyl tapes such as Scotch 33+ and Super 88 are rated up to 105°C.

Which 3M tape is for electric motors and transformers?

Scotch 27 glass cloth is often used for windings because of its Class B 130°C rating. Make sure your working temperature and voltage match the data sheet.

Which 3M tape is for electronic components and soldering?

Polyimide tape such as 3M Tape 92 is commonly used for wave-solder masking and component insulation. Ask SinarCS about availability.

What is the maximum temperature of Scotch 27?

3M's data sheet lists 130°C continuous and 160°C short term. Some seller descriptions list different figures, so ask for the official data sheet.

Is vinyl electrical tape heat resistant?

Up to a point. Scotch 33+ and Super 88 are rated up to 105°C, while Temflex 160 is rated up to 80°C according to 3M. Above that, use glass cloth or polyimide.

What is the difference between continuous and short-term temperature?

Continuous temperature is what the tape withstands in constant use. Short-term temperature applies only to brief exposure and is higher.

Where can I buy genuine 3M tape in Jakarta?

SinarCS in West Jakarta sells 3M tape in its Industrial Tape category and says it is an official 3M distributor. You can reach them at (+62) 21 5431 7537.

How much does Scotch 27 cost at SinarCS?

As of October 28, 2026, Rp139,000. Prices can change, and size and packaging need to be confirmed.

Is heat-resistant tape safe for all voltages?

No. Check the voltage rating on the data sheet. The tapes discussed here are rated up to 600 V.

Conclusion

For electronic components and industrial machinery, choose tape by continuous working temperature, voltage and function. According to 3M, vinyl suits temperatures up to about 105°C, Scotch 27 glass cloth suits continuous use up to 130°C on motors and transformers, and polyimide Tape 92 suits needs up to 180°C such as PCB soldering.

In the SinarCS catalog, Scotch 27 is the most relevant option for heat on machinery, but because the temperature data in the seller's description differs from 3M's, confirm the data sheet before ordering.
