3M™ Thermally Conductive Silicone Interface Pad 5591 is designed to provide a preferential heat transfer path between heat generating components and heat sinks, heat spreaders or other cooling devices. 3M™ Thermally Conductive Silicone Interface Pad 5591 consists of a highly conformable and slightly tacky silicone elastomer sheet filled with thermally conductive ceramic particles, which helps provides enhanced thermal conductivity and excellent electrical insulation performance.

FEATURES

  • Very good softness and conformability even to non-flat surfaces
  • Good thermal conductivity
  • Good electrical insulation properties
  • Compression relaxation properties help reduce pressure to electric components
  • Slight tack allows pre-assembly
  • Good wettability for improved and lower thermal resistance

APPLICATIONS

  • Integrated chip (IC) packaging heat conduction
  • Heat sink interface
  • Chip on film (COF) heat conduction
  • LED board thermal interface material (TIM)
  • HDTV integrated chip (IC)
  • General gap filling in electronic device
