Thermal Management Materials

In today’s electronic devices, battery applications and even LED lighting, efficient heat transfer from the heat source to a cooling device is critical to long term successful device operation. Heat spreaders, gap fillers, thermal bonding tapes, and foams help in the efficient transfer heat. Die-cut thermal interface materials (TIMs) are light weight and easy to handle. Die-cut thermally conductive tapes, foils and gap pads are utilized over greases and liquid adhesives due to easy application and consistent performance.  Marian can help design and manufacture custom thermally conductive components to meet the specifications of your application. Marian has access to a wide range of thermal management materials through strong supplier relationships with Polymer Science, NeoGraf, Saint Gobain, 3M and Rogers Corporation.
