CoolZorb 400

Hybrid Thermal/EMI Absorber

Product Description

CoolZorb 400 is a hybrid absorber/thermal management material that is used for EMI mitigation and heat dissipation. It is used like a traditional thermal interface material between a heat source, such as an IC, and a heat sink or other heat transfer device or metal chassis. CoolZorb 400 also functions to suppress unwanted energy coupling, resonances or surface currents causing board level EMI issues.

Features and Benefits
  • High thermal conductivity with good EMI suppression within 10-40GHz
  • Inherent surface tack typical of standard thermal gap fillers
  • Meets UL 94 V-0 flame requirements
  • Dual functional properties of thermal conductivity and EMI reduction provide two in one solution for easier design and assembly and lower cost of ownership
  • Improved reliability performance of electronicsBetter signal integrity due to reduction of EMI
  • Consistent performance of electronics due to temperature stability and low outgassing properties of product
  • Improved EMC performance and resultant lower cost to meet compliance requirements
  • Environmentally friendly solution that meets regulatory requirements including RoHS and REACH
