3M™ Thermally Conductive Heat Spreading Tape 9786


3M 9876-10

3M™ Thermally Conductive Heat Spreading Tape (TCoHST) 9876 is designed to provide excellent heat spreading performance on the x-y plane direction

3M™ Adhesives for electronics offer an advanced new approach to bonding. Their superior depth of cure, rapid cure speed and easy dispensability can save valuable processing time in UV and visible light curing assembly environments.


  • Excellent thermal conductivity on plane direction (>200W/m-K)
  • Selective thermal spreading path for uniform heat distribution
  • Excellent flexibility without any wrinkle and bending by fold
  • Good light shielding property
  • Low thermal impedance
  • Good and reliable adhesion performance against Al and SUS
  • Easy workability and handling convenience (easy die cut)

Typical Applications: 

  • Heat spreading sheet on FPD (Flat Panel Display) for thin, space constrained devices - LCD with LED BLU, PEP Module, OLED Module
  • Thermal spreading/conduction on Lighting, ECU, Solar Cell, 2nd Battery and Electrical Recharger Module
  • Heat Distribution on LED module/ board
  • Small display for MHH as LCD and OLED
  • COF Chip Thermal Management for Uniform Temperature
