Features and Benefits
• Thermal conductivity: 2.0 W/m-K
• Low “S-Class” thermal resistance at very
• Highly conformable, low hardness
• Designed for low-stress applications
• Fiberglass reinforced for puncture, shear
Gap Pad 2000S40 is recommended for low-
stress applications that require a mid to high
thermally conductive interface material.The
highly conformable nature of the material
allows the pad to fill in air voids and air gaps
between PC boards and heat sinks or metal
chassis with stepped topography, rough
surfaces and high stack-up tolerances.
Gap Pad 2000S40 is electrically isolating, and
well suited for applications requiring electrical
isolation between heat sinks and high-voltage,
bare-leaded devices. Gap Pad 2000S40 is a
filled, thermally conductive polymer reinforced
with a fiberglass carrier on one side, allowing
for easy material handling and enhanced
puncture, shear and tear resistance.
Note: Resultant thickness is defined as the final gap
thickness of the application.
