What Is the Difference Between Electrical Tape and Heat Shrink Tubing?

Heat shrink tubing and electrical tape are commonly used tools among those in the automotive, electrical, and telecommunication professions. Because of this, many people are under the impression both can perform the same job. Unfortunately, this is not the case.

Both electrical tape and heat shrink tubing can be used as an insulator, protector, and for identification purposes, depending on the job at hand. While each one has its own viable properties, they shouldn’t be used interchangeability in all situations.

In this article, we will look at the similarities and differences that set heat shrink tubing and electrical tape apart. 

What Is Electrical Tape & How Does It Work?

Electrical tape is a vinyl, rubber, or mastic material with an adhesive side that is capable of attaching to metal, plastic, and rubber. This type of pressure sensitive tape is also known as insulating or friction tape. It provides resistance to electrical currents of up to 600V. 

It is typically used to wrap around wiring components as a protective layer. The properties of the tape work to stop electrical currents from passing to other wires, which may cause an electrical fire. Electrical tape also works as an insulator. 

What Is Heat Shrink Tubing & How Does It Work?

Heat shrink tubing is a thermoplastic material, usually made from polyolefin, that placed around wires, cables, and connectors. Often referred to as sleeves, this tubing relies on a heat source to shrink its diameter and therefore form a tight seal around the wiring. 

By forming a protective layer around the wires or cables, the heat shrink tubing can insulate the delicate electrics. It also works as protection against abrasion, extreme weather conditions, damage, and moisture. 

The Difference between Electrical Tape and Heat Shrink Tubing   

Can You Use Electrical Tape Instead of Heat Shrink Tubing?

Whether electrical tape can be used instead of heat shrink tubing depends on the application itself. The product, location, and environment all need to be taken into consideration.

The quick ease of use and access to electrical tape makes it the favorable choice for easy repairs and added protection to wires and cables. But the adhesive must be properly secured to last and can easily wear off, tear, or be unraveled with movement. 

For projects where a layer of protection or insulation is required for long-lasting use, heat shrink tubing is the better choice. While the tubing requires the use of a heating mechanism for a tight fit, it cannot be easily removed or worn down. This ensures longevity and makes heat shrink a more reliable option.
