Thermal Gap Filler Thermal Conductive Material Thermal Pad 30
seconds Hardness
A-gapfill 600 is an exceptionally soft, highly compliant gap
filling interface pad with a thermal conductivity of 3 W/mK. These
outstanding properties are the result of a proprietary boron
nitride filler in the composition. The high conductivity, in
combination with extreme softness produces incredibly low thermal
resistances. A-gapfill 600 is naturally tacky and requires no
additional adhesive coating that can inhibit thermal performance.
A-gapfill 600 is electrically insulating, stable from –45°C to
200°C and meets UL 94 V0 rating.
FEATURES
• Very high compliancy for low stress applications
• 3 W/mK thermal conductivity
• Available in thicknesses from 0.020” - 0.200” (0.5mm - 5.0mm)
• Naturally tacky, needs no further adhesive coating
APPLICATIONS
• Cooling components to the chassis or frame
• High speed mass storage drives
• RDRAM memory modules
• Heat pipe thermal solutions
• Automotive engine control units
• Telecommunications hardware

STANDARD THICKNESSES
0.020 to 0.200-inch (0.5 to 5.0mm)
0.020 to 0.200-inch thick material available in 0.010-inch (0.25mm)

0.200-inches
STANDARD SHEET SIZES
9 x 9” (229 x 229mm). 18 x 18” (457 x 457mm). 9 x 9” only over
0.100” thickness. A-gapfill 600 can be die cut to individual
shapes. Pressure sensitive adhesive is not applicable for A-gapfill
600 products.
TACKY ONE SIDE ONLY
A-gapfill 600 is naturally tacky on both sides. A-gapfill 600 can
be provided tacky on one side only. This is indicated by the suffix
“DC1”. This option offers good separation properties allowing the
tacky side to stick to the heatsink/chasis/cold plate/etc. and the
other “dry” side to release easily from the component(s).
REINFORCEMENT
Fiberglass is required in 0.020” (0.51mm) and 0.030” (0.76mm).
Thicknesses of 0.040” (1.02mm) and above do not require
reinforcement. Data for design engineer guidance only. Observed
performance varies in application. Engineers are reminded to test
the material in application.
