Potting & Encapsulants for Battery Thermal Management

Thermally connect your cells to the heatsink by encapsulating the entire pack and minimize design gaps by taking advantage of high dielectric strength.

  • Improve Performance: Our encapsulants facilitate optimum heat transfer because of their high thermal conductivity and low viscosity.
  • Protect Electronics: Potting and encapsulants provide protection from dust and moisture and can reduce vibration.
  • Reduce Component Stress: LORD encapsulants exhibit low shrinkage upon curing.

Thermally Conductive Adhesives for Battery Pack Assembly

Formulated for standard MMD equipment, our adhesives provide your application with structural integrity. Our thermally conductive adhesives not only provide mechanical rigidity but also a thermal connection where heat is a problem.

  • Improve Design Flexibility: No longer constrained by mechanical fixtures and given the ability to bond a wide variety of substrates, you are free to discover the possibilities.
  • Reduce Complexity: Reduce the need for fasteners, thereby simplifying your battery pack design.

Gap Fillers for Battery Thermal Management

Get the best performance out of your batteries by filling in surface imperfections with a thermally conductive gap filler designed with electric vehicle applications in mind. They are a stay-in-place solution and cure as a gel, easing the stresses caused by thermal differences and flex.

  • Low Outgas Options: We offer low ppm siloxane solutions for sensitive electronic applications.
  • Protect Against Shock: Our gap fillers remain tacky and soft to dampen vibration.
