Power Electronics Thermal Management
Improve Thermal Stability with CoolTherm® Materials
Protect components and improve stability - In order to extend the life of your power electronics, you need to maintain low thermal resistance and protect components from shock, moisture and debris. LORD CoolTherm® low viscosity, highly thermally conductive pottants provide a robust thermal interface, as well as protect delicate electrical components. Additionally, we offer a variety of other thermal interface materials — available in gels, greases, adhesives and gap fillers — that will not only improve heat flow but also provide excellent isolation and vibration dampening.
Our dedicated technical service staff will work with you on a customized solution and can help select the correct material for your application that aligns with your cost targets and process for improving performance.
Potting & Encapsulants for Power Electronics Thermal Management
Our thermally conductive encapsulants provide electrical isolation and protection, and their low viscosity enables better impregnation and displacement of air.
- 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 help reduce vibration.
- Reduce Component Stress: LORD encapsulants exhibit low shrinkage upon curing.

Gap Fillers for Power Electronics Thermal Management
Get the best performance out of your components by filling in surface imperfections with a thermally conductive gap filler. 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.
