I have searched for high-temperature copper adhesive tape, but found no tape that combines both a copper backing and a specialized high-temperature adhesive for extreme environments. The available products are copper foil tapes designed for electrical conductivity and EMI shielding, with limited heat tolerance-1-4-5.
To help you find a suitable product, I have compiled the key performance data of common copper foil tapes and high-temperature tapes from different materials for comparison.
???? Copper Foil Tape Performance Overview
The table below summarizes copper foil tapes, which are primarily designed for electrical applications and offer moderate temperature resistance.
| Product / Model | Temperature Range | Key Adhesive/Backing Features | Primary Applications |
|---|---|---|---|
| 3M™ Copper Foil Tape 1126-5 | -40°F to 266°F (-40°C to 130°C) | Flame-retardant acrylic adhesive, copper foil backing | EMI shielding, cable wrapping, static draining |
| Discount-Autosport Copper Tape-2 | -40°C to +200°C | Resistant to over 600V, copper backing | Electrical insulation, EMI/RFI shielding |
| Tapedepot Conductive Tape-7 | Operating Temp: Class F (155°C) | Conductive acrylic adhesive, 1 oz rolled copper foil | Cable wrapping, EMI/RFI shielding, static draining |
| CGS Copper Tape-1 | Not specified in search results | Acrylic adhesive (conductive or non-conductive), malleable copper foil | EMI shielding, arts & crafts, electrical repairs |
????️ High-Temperature Alternatives: Aluminum & Fiberglass Tapes
If your application involves much higher temperatures (e.g., above 250°C), you will need to consider tapes with different materials. These products are designed for thermal insulation and heat reflection, not electrical conductivity.
| Material / Product | Temperature Range | Key Features & Limitations | Typical Use |
|---|---|---|---|
| Aluminized Fiberglass Tape-8 | Up to 1200°F / 648°C (base fabric) Adhesive limits: ~450°F / 232°C (continuous) | Reflects radiant heat. Adhesive may degrade before base fabric. | Protecting wires/cables near intense heat sources (exhaust, furnaces). |
| Aluminum Foil Tape (Silicone Adhesive)-8 | Peak: 1000°F / 537°C Continuous: 450°F / 232°C | High-temp silicone adhesive. Better for intermittent high heat. | Heat shielding, sealing, and protection in industrial/automotive settings. |
| Stainless Steel Foil Tape-8 | Peak: 1000°F / 537°C Continuous: 450°F / 232°C | Very stiff, holds form well but can crease. Excellent durability. | High-heat environments requiring a robust, reflective barrier. |
???? How to Choose the Right Tape
To narrow down your options, please consider the following questions related to your specific needs:
Primary Goal: Is electrical conductivity your main requirement, or is heat shielding more critical?
Temperature Details: What is the maximum continuous operating temperature and the nature of the heat (e.g., ambient, radiant, direct contact)?
Application Context: Will the tape be used in an electronics project, for industrial equipment protection, or in an automotive/engine environment?https://store.unigulfsupply.com/product/copper-adhesive-high-temperature-tape/
