tesa® 58326

Product description

tesa® 58326 is a 1200 μm thermally conductive pad. This acrylic based thermally conductive product provides high thermal conductivity with its thermally conductive fillers when it is applied between heat source and heat sink to transfer the heat. Besides that, it also has excellent electrical insulation property and flame retardancy.

Application Fields

Applied between heat source and heat sink to transfer the heat:
  • EV battery between module and cooling system
  • Power electronics between chips
  • PCB and heat sink
