Electrical tape is a household essential used by electricians and DIYers alike. Its primary purpose is to insulate wires and other electrical connections. Gorilla Tape, known for its incredible strength and versatility, is another popular multi-use tape. But can it serve as a substitute for electrical tape in a pinch?
Comparison Table For Electrical Tape Vs Gorilla Tape
| Feature | Electrical Tape | Gorilla Tape |
| Purpose | Designed for insulating electrical wires and connections | Heavy duty repairs, construction projects, etc |
| Backing Material | Vinyl, rubber, or combination | 3 layers – Double thick fabric + extra adhesive layer |
| Adhesive | Specialized to insulate against electricity | Rubber-based for waterproof, weatherproof bond |
| Reinforcements | None | Fiberglass threads woven into fabric |
| Heat Resistance | High heat and flame resistance | Not designed for high heat applications |
| Tearability | Thinner backing tears easily | Despite thick backing, tears by hand |
| Flexibility | Highly flexible to mold tightly | Flexible enough to conform to uneven surfaces |
As shown in the table, while both tapes are flexible and strong, electrical tape is designed specifically for insulation in electrical applications due to its dielectric backing and adhesive. Gorilla tape has a thicker and more durable construction for repairs and construction but lacks the heat and voltage resistance of electrical tape. The choice between the two depends on the specific application and requirements.
Can You Use Gorilla Tape as Electrical Tape?
Gorilla Tape has many desirable strength properties. But how does it measure up for electrical applications compared to true electrical tape? Here are factors to consider:
Insulating Ability
Gorilla Tape is not designed or rated to safely insulate electrical connections. The fabric backing and rubber adhesive likely have significantly lower dielectric strength than vinyl electrical tape. This means it may not effectively prevent voltage arcing or electrical current passage.
Heat Tolerance
Standard Gorilla Tape begins to soften and melt at temperatures around 200°F. Electrical tape can often withstand temperatures up to 300°F or higher before breaking down. Exposed wires can reach similar temperatures.
Adhesion Properties
While Gorilla Tape bonds very aggressively to surfaces initially, its adhesive properties change over time. Electrical tape retains a more stable adhesive ability long-term.
Conformability
Gorilla Tape is thicker and less malleable than electrical tape. It may be more difficult to wrap tightly around wires without air gaps.
Appearance
Electricians usually use black electrical tape for a discreet professional look. Gorilla Tape only comes in silver/gray.
Dangers of Using Gorilla Tape for Electrical Work
While Gorilla Tape may seem like a quick fix, using it to insulate live electrical connections or splice wires comes with risks:
Potential Fire Hazard
If wires heat up, Gorilla Tape could soften, melt, or burn, exposing wires and leading to electrical arcing and sparks. This may result in a fire.
Short Circuits
If Gorilla Tape lacks the dielectric strength to fully insulate, wires could short circuit or voltage could leak to nearby conductive surfaces creating a shock hazard.
Adhesive Breakdown
As Gorilla Tape adhesive deteriorates over time, the tape backing may come loose and expose bare wires.
Ineffective Protection
Gorilla Tape applied too thickly may compromise wire connections. Applied too thinly, it would not properly insulate. It takes experience to apply electrical tape correctly.
Code Violations
Using Gorilla Tape on electrical systems may violate building codes or burn hazard regulations. This could void insurance policies.
Better Alternatives to Gorilla Tape
Rather than risk safety with Gorilla Tape, consider these alternatives when electrical tape is unavailable:
Purchase Electrical Tape
It is inexpensive and available at any hardware store. Select a tape rated for the voltage of your electrical project.
Use Heat Shrink Tubing
Flexible tubing shrinks when heat is applied to fully insulate connections. It comes in various sizes.
Try Self-Fusing Silicone Tape
This specially engineered tape only sticks to itself, not surfaces. It insulates and protects well.
Use Electrical Insulating Putty
This putty can fully encapsulate electrical connections to prevent shocks and shorts.
Wrap with Electrical Insulating Rubber Tape
Multiple layers of quality rubber tape can substitute for vinyl electrical tape.
Conclusion
While Gorilla Tape excels at repairs and construction applications, it should not replace electrical tape for insulating wires and connections. The adhesives, materials, and construction of Gorilla Tape are not designed to safely perform in electrical environments. Select a product specifically engineered for electrical insulation or speak with an electrician to avoid hazardous shortcuts. Investing a few dollars in the proper tape can prevent electrical fires, shocks, and other safety risks.
