Technical Adhesives for Electrical Assemblies
Electrical Adhesives can be used to bond together different components within an electrical assembly. These bonding adhesives are often used for ease of assembly, electrical isolation, thermal management, EMI protection, and other properties.
Here at Materials Direct, we offer a wide range of electrical tapes and electrical adhesives that can be custom cut to meet your specification.

Double Sided Adhesive Tapes
Material Direct is growing this sector by offering a large variety of Electrical tapes and adhesives with different characteristics needed in your industry.
Many double-sided adhesive tapes can be roller die-cut to produce “custom parts” on a roll. This is not only a fast production method but keeps the parts very clean as they only become exposed to the environment as they are unrolled.
This helps keep parts in pristine conduction as they are being used. They also avoid picking up foreign bodies in the assembly.
Thermal Management
For linear printed circuit boards such as LED line light assemblies, Bondline Adhesives can be applied to the rear of the PCBs using a simple applicator.
The Bondline range has electrical Isolation, good mechanical strength, and high thermal conductivity. This removes the need for mechanical fixing points on the PCB.
Electrical Tapes and Adhesives can not only save time but can provide high-quality bonding and protection for your electronic assemblies.
High Voltage Breakdown
Most technical tapes used in Electronic applications have multiple special characteristics other than being a bonding film such as high Voltage breakdown.
Technical Adhesives with this range of characteristics allow for better performance of not only its bond but that of your electronic devices. This is due to the protection from environmental factors as well as internal ones.

Frequently Asked Questions
What is electrical tape used for?
There are many types of electrical tape used in electronic applications. Some of which include:
- Electrical isolation
- EMI shielding
- Mechanical bonding
- Thermal interfacing
- Sealing and bonding
- Electrically conductive
- Double-sided flexible
- Intumescent fire protection
- Indicating tapes such as exposure to water for warranty purposes.
What is the most common application for tape and adhesive in electronics?
The most common types are for electrical isolation and protecting against EMI.
Can electrical tape catch fire?
Most tapes can burn at high enough temperatures, the key is to understand what the requirements are for your application. There are standards such as UL laboratories V-Rating for materials. A good rule of thumb is if you have a risk of the materials being exposed to high temperatures assure the UL rating is sufficient for the application. UL V0 is often specified for Electronic applications and more recently Electric vehicle Energy storage (Battery) packs
How do I use electrical tape?
Most tapes supplied by Materials Direct are continuous rolls of single or double adhesive coated tapes. The material is supplied with a single or a double protective liner. If we are supplying cut parts on a roll then the material sits on a baseliner ready to be removed (with a top liner the same shape as the cut part) and applied and bonded to your component. Once the material is applied the second liner is removed exposing the top bonding surface.
If we supply material with a single liner the material's sticky surface is exposed as you unroll it ready for applying directly to your component.
What are the benefits of supplying cut shaped parts on a roll?
The use of parts on a roll means they are always clean as they come off the roll. They do not attract debris and swarf often present in assembly environments as they are not laying around waiting to be used. They are effectively covered until they are needed to be applied. Counting the parts during manufacturing is easier and so quantity and quality is assured. This method is reserved for high-volume applications as there are special rotary die-cutting tools needed to manufacture the parts. If the material is simply a roll of material without cut shapes then the application of linear lengths can be achieved by running the exposed adhesive in a channel and applying the component (often a long PCB or metal board) to the exposed adhesive side sliding it along and cutting across the tape
