Soft Thermal Sheet Thermally Conductive Pad Gap Filler For Led
Lights
A-gapfill 200 is a very soft, freestanding gap filler that is more
compliant than most other gap fillers. Combining good thermal
conductivity of 1.1 W/mK with high conformability, this gap filler
produces low thermal resistance. The alumina filler allows the
product to remain a cost effective solution where moderate thermal
performance is acceptable. Naturally tacky and not requiring
additional adhesive coating, the
A-gapfill 200 can inhibit thermal performance. This gap filler is
both electrically insulating and stable from -40°C to 160°C and
meets UL 94 VO rating.
FEATURES
• Soft and compressible for low stress applications
• Naturally tacky needing no further adhesive coating
• 1.1 W/mK thermal conductivity
• Available in thicknesses from 0.010” (0.25mm) to 0.200” (5.0mm)
APPLICATIONS
• Cooling components to the chassis or frame
• High speed mass storage drives
• RDRAM memory modules
• Heat pipe thermal solutions
• Automotive engine control units
• Wireless communication hardware
