Thermal Management Solutions

SPREADERSHIELD™ products distribute heat evenly while providing thermal insulation through the thickness. This unique combination of spreading and shielding properties make flexible graphite an excellent material choice for thermal solutions. SPREADERSHIELD products are offered in a variety of engineered in-plane thermal conductivities, from 300-1500 W/m-K. By eliminating heavy thermal solutions, SPREADERSHIELD products have enabled slimmer product design and reduced product weights by up to 50%.

Features and Benefits:

  • Engineered thermal conductivity up to 1500W/m-K outperforms Copper and Aluminum
  • Eliminate "hot spots"
  • Shield components and external surfaces
  • Reduce skin temperature
  • Flexible enough to conform to product contours
  • Performance reliable up to +400°C
  • Can eliminate the need for fans and heat pipes
  • Thickness from 0.05mm (0.002")
  • 80% lighter than Copper
  • 30% lighter than Aluminum
  • Can be die-cut, laminated with plastics, metals or elastomers to meet mechanical and electrical criteria
  • Can be adhesive-backed for peel-and-stick attachment
  • Always manufactured to specific product dimensions and shape
