Hybrid Thermal/EMI Absorber  

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

11.5

W/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  

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
