Material Spotlight: Avery Dennison Volt Tough Electrical Insulation Solution

die cut presssure senstive adhesive for battery applications

With the electric vehicle sector projected to be valued at 1,891 billion dollars by the year 2032, manufacturers are constantly seeking advancements in new production materials and methods to increase production efficiency and vehicle performance. Companies such as Avery Dennison Performance Tapes have been at the forefront of engineering these performance materials, one such example being their Volt Tough line of adhesives.

The Avery Dennison Volt Tough line is a line of specialty dielectric pressure-sensitive adhesives (PSAs) that was introduced to the market at the 2023 Battery Show North America. With its high-dielectric strength, instant bond, and durability, the Volt Tough line has many applications in electrical battery insulation.

In today's Material Spotlight, we’re focusing on a new addition to the Volt Tough line: Volt Tough Stretch.

Why Volt Tough Dielectric Tapes?

According to Max Vanraaphorst Avery Dennison’s Business Development Manager - E-Mobility, Energy Storage and Automotive, Volt Tough Stretch was engineered to help alleviate problems that manufacturers often face with other electrical insulation methods like spray coating and traditional PSAs. Paramount among these problems is the issue of durability and flexibility, which, he said, is where other methods of electrical insulation often fail.

Dynamic Durability, Functional Flexibility

Typically, a weak spot for traditional dielectric tapes has been their inability to conform to complex geometries.  Forming secure bonds across areas of complex geometries and sharp corners can cause most PSAs to tear or fail in some capacity. Engineered to solve this issue, Volt Tough Stretch allows for flexibility and durability not found in other PSAs creating new possibilities for battery applications.

In areas of complicated geometry or sharp corners, Volt Tough Stretch is durable enough to resist tears and weak spots while providing high dielectric functionality.

Other methods like spray coating can result in weak spots on sharp corners and edges. This can be problematic since there is typically a concentration of charge in these areas.

Here’s a quick overview of the Features and Benefits of Volt Tough Stretch.
