Thermal Management: Heat Spreader

Thermal Heat Spreader Overview and Value Proposition

  • G3’s graphene thermal heat spreader provides superior thermal management in the form of high thermal conductivity films / sheets and enhanced heat dissipation in a lightweight and non-combustible film
  • The thermal heat spreader can be easily cut and laminated, making it compatible as a drop in solution for a variety of electronic applications
  • The AT 1500 series of heat spreaders come in a variety of thickness options ranging from 20 – 300 um
  • The heat spreader is currently in mass-production in the capacity-expanding phase
  • Applications: 3C industry, large screen displays, LED lighting

Performance

  • G3’s graphene heat spreader offers substantially higher thermal conductivity than competing materials such as copper, aluminum and magnesium alloys
  • G3’s graphene heat spreader dissipates heat quicker and more efficiently than other materials, able to maintain a temperature of 74.1° C compared to the heat source at >150° C
