Potting & encapsulation compounds for lithium-ion battery Packs

Our lithium-ion battery potting materials protect from moisture and chemical exposure while guarding against damage from mechanical and temperature shock. Lightweight lithium batteries are ideal power sources for smaller consumer products exposed to environmental stresses.

We design, formulate, and manufacture polyurethane and epoxy resin potting and encapsulating compounds for lithium-ion (Li-Ion) battery packs. Our products can overcome and work to avoid thermal runaway propagation. Where applicable, we will help you choose the right compound for mitigating thermal runaway in your lithium-ion battery. We partner with our customers, managing issues with thermal conductivity, thermal cycling, thermal shock chambers, and extremely high and low temperatures.

Polyurethane & Epoxy Resin Li-Ion Battery Products

Finding a potting compound to satisfy the needs of all lithium-ion applications can seem impossible. Our in-house formulators create potting and encapsulating compounds to nearly any specification your lithium-ion battery needs for optimized performance.

We can adapt one of our many existing formulations or create a potting compound specific to your product.

Popular Li-Ion Battery Potting Compounds:

 

  • Epic S7475 is a 2-component polyurethane compound
  • Designed for potting electronic devices.
