Key benefits of 3M Glass Bubbles for xEV battery assembly and production

Lighter materials to enable greater range

Using 3M glass bubbles as a lightweight additive for battery components – and components throughout the vehicle – can translate into increased range for xEVs and increased fuel efficiency for hybrid vehicles. Inherent low dielectric and high electrical insulating properties of 3M glass bubbles can lead to lower power loss and more robust battery performance over time.
Enabling process efficiencies

Our high-strength, low-density microspheres with good flow characteristics can withstand the high pressures of compounding and injection molding. They can also enable faster cooling for cycle time reduction and allow for reduced operating pressures. This can translate into lower production costs overall.

Key considerations for design engineers

Our 3M glass bubbles have been instrumental for automotive lightweighting in body and under hood/dash applications. Now, they deliver key properties that help optimize designs and material selection in hybrid and EV battery components.

Consistent thermal expansion and contraction

The isotropic spherical geometry helps promote uniform thermal expansion and contraction for increased dimensional stability.
Lighter and more uniform parts

Compared to conventional fillers, 3M glass bubbles fillers allow you to create lighter, more uniform parts from polypropylene, nylon, acetal and other engineered thermoplastics, as well as many thermoset materials.
May help decrease reactive burning

Being chemically inert and often displacing polymer resin, 3M glass bubbles can help decrease reactive burning during a thermal runaway event.
