CoolTherm® potting, encapsulants, adhesives, and gap fillers are fully customizable and compatible with cylindrical, pouch, and prismatic battery cells.
Thermally connect your cells to the heatsink by encapsulating the entire pack and minimizing design gaps by taking advantage of high dielectric strength.
Get the best performance out of your batteries by filling in surface imperfections with a thermally conductive gap filler designed with EV applications in mind. They are a stay-in-place solution and cure as a gel, easing the stresses caused by thermal differences.
Formulated for standard MMD equipment, our thermally conductive structural 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.
Watch Now
As consumer demand for higher-performing electric vehicles continues to rise, so does the need for highly engineered solutions that enable these vehicles to have higher power density, faster charging, and increased safety and reliability. Parker Lord is a total solutions provider to OEMs and Tier suppliers looking to design highly reliable electronic components for electric vehicle end-use.
We specialize in developing world-class thermal management solutions that include thermally conductive (TC) gap fillers and structural adhesives shown in the image above. Our liquid-dispense, cure-in-place gap fillers provide low stress on batteries and improve thermal resistance when compared to thermal pads. Similarly, our structural adhesives couple high-bond strength with thermal conductivity for ease of use and cost-savings.
As battery technology evolves towards increased energy density, the ability to manage heat during charge and discharge cycles is crucial for optimizing performance. Our CoolTherm potting and encapsulants, shown in the image above, are fully customizable and compatible with lithium ion cylindrical, pouch, and prismatic battery cells. Our structural adhesives allow design flexibility and the ability to bond a variety of substrates.

Traditional joining techniques in the automotive industry include welding and mechanical fasteners. However, many challenges arise when using these methods. By using structural adhesives, the need for mechanical fasteners as well as post-weld rework is eliminated. Adhesives also eliminate heat-affected zones and can double as a sealant.
For industries ranging from electric forklifts to eighteen-wheelers and everything in between, our high-quality products cater to industrial batteries of all sizes. Available off the shelf, our materials are designed to meet the diverse needs of a broad spectrum of industries. Discover the extensive range of non-automotive sectors we serve.

The purpose of this study was to compare the thermal impedance of CoolTherm® gap fillers versus commercially available thermal pads having equivalent bulk thermal conductivities. Data from this and future studies on battery packs will better enable designers to develop more efficient and cost-effective battery packs.
Electric vehicles - including automobiles, buses, trains, off-road vehicles, watercraft, and aircraft are here to stay. A key challenge in developing higher-power-density electronics for electric vehicles and other applications is to manage the heat. This e-book covers topics crucial to thermal management in your applications.
Assembling electric vehicle (EV) battery boxes using structural adhesives instead of mechanical fasteners not only results in process efficiencies but can help installed boxes perform better. Here are five ways how.
There are 3 main types of cooling systems used in EV battery packs today. Learn more about these types and how they effect battery degradation.
From arcing to shorting out, protecting against electrical failures in an EV application can be challenging. To reduce these electrical issues, dielectric coatings have become a popular solution.
