Laird CoolZorb 400: A Hybrid Absorber and Thermal Management Material

CoolZorb 400 is a hybrid material engineered for both EMI mitigation and thermal management. It’s applied like a traditional thermal gap filler - positioned between a heat source, such as an integrated circuit (IC), and a heat sink, metal chassis, or other heat-dissipating surface.

Beyond its thermal function, CoolZorb 400 helps suppress unwanted energy coupling, resonances, and surface currents that can contribute to board-level EMI issues.

Benefits

  • High thermal conductivity (2 W/mK) with effective EMI suppression across the 10–40 GHz range
  • Naturally tacky surface for easy placement, similar to standard thermal gap fillers
  • Enhances overall reliability of electronic systems
  • Tested to meet UL 94 V-0 flame requirements
