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.
– 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
