CoolZorb™-Ultra

CoolZorb™-Ultra

Hybrid Thermal/EMI Absorber

CoolZorb-Ultra series is a higher performance and silicone free hybrid absorber/thermal management material with ultra-high thermal conductivity of 11.5W/m.K. CoolZorb-Ultra is designed to be used like a traditional thermal interface material between heat source such as a high-power IC and heat sink or other heat transfer device or metal chassis. CoolZorb-Ultra also functions to suppress unwanted energy coupling, resonances or surface currents causing board level EMI issues.

Features and Benefits

  • Very high thermal conductivity to meet industry trend of increasing IC power 
  • Good EMI suppression over wide frequency range, particularly over 25GHz 
  • Silicone free formulation make it suitable for silicone sensitive application 
  • Inherent surface tack typical of standard thermal gap fillers 
  • Compliant with minimal component stress during assembly 
  • CoolZorb Ultra passes UL94V0 requirements
