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 60GHz 

• 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 

VALUE  

• Performance advantage comes from dual functional properties of thermal conductivity and EMI reduction 

• Improved reliability performance of electronics   

  – Better signal integrity due to reduction of EMI 

  – Consistent performance of electronics due to temperature stability and low outgassing properties of product 

• Improved EMC performance to meet compliance requirements 

• Environmentally friendly solution that meets regulatory requirements including RoHS  and REACH
