5550H Thermally-Conductive Acrylic Interface Pad

3M’s interface pad incorporates a thin, firm acrylic layer for good handling

Image of 3M™ 5550H Thermally Conductive Acrylic Interface Pad3M™ thermally-conductive acrylic interface pad 5550H is designed to provide a preferential heat-transfer path between heat-generating components like an IC chip or EV batteries and heat spreader. With higher thermal conductivity (3.0 W/mK) and low hardness (Asker C 5), the 3M pad 5550H consists of a highly conformable, slightly tacky acrylic elastomer sheet filled with conductive ceramic particles.

Features
  • High conformability, even for non-flat IC surfaces and automotive batteries
  • Incorporates a thin, firm acrylic layer for good handling
  • High thermal conductivity while being electrically insulating
  • Slight tack allows pre-assembly
  • Good wettability for better thermal conductivity
  • No siloxane gas/oil bleeding, which can cause an electric connection failure
  • UL94 V-0 certified (File no. E176845)
  • White/gray color
  • Thickness ranging from 0.5 mm to 1.0 mm, with thicker pads available upon request
  • Acrylic base resin and ceramic filler type
Applications
  • Heat transfer between PCB and heat sink
  • Thermal management in automotive batteries
  • Power electronics component thermal management
  • Chip-on-film (CoF) heat conduction
  • LED thermal management
  • HDTV IC chip
  • General gap-filling in electronic devices
