CooLam® thermal substrates

CooLam® thermal substrates are used in submount, chip-on-board and metal core PCB LED packaging applications.These thermal clad laminates are a composite of metal foil, proprietary polyimide dielectric with thermally conductive inorganic fillers bonded to a metal base, and provide an ideal insulated metal substrate for high brightness LED lighting.

DuPont offers two CooLam® product types for today's demanding thermal applications.

  • CooLam® LA is designed for general LED lighting, LCD TV and LED backlight units.
  • CooLam® LX is designed for LED high bay lighting and outdoor LED lighting, where very low thermal impedance is required.
  • CooLam® 3D is designed for innovative omnidirectional A-19 replacement bulbs and general lighting fixtures.

Key properties of DuPont™ CooLam® thermal substrates:  

  • Low thermal resistance allows more light output at the same current
  • Fewer LEDs achieve the same level of light intensity
  • LEDs run cooler and longer

Features Include: 

  • Very low thermal impedance
  • Excellent durability and stability at high temperature
  • UL 94 recognition: V-0
  • Halogen free
  • Lead free solder compatibility
  • RoHS compliant

Applications Include: 

  • General lighting
  • Automotive lighting
  • Back light units (BLUs) for LCD displays in:
    • Notebook and desktop computers
    • Televisions
    • High end monitors for medical and industrial uses
