GP-HC3.0 Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – Thermal Conductivity: 3.0 W/m-K
Gap Pad® HC 3.0
April 2015
PRODUCT DESCRIPTION
High-Compliance, Thermally Conductive,
Low Modulus Material
FEATURES AND BENEFITS
• Thermal Conductivity: 3.0 W/m-K
• High-compliance, low compression stress
• F iberglass reinforced for shear and
tear resistance
Gap Pad® HC 3.0 is a soft and compliant
gap filling material with a thermal
conductivity of 3.0 W/m-K. The material
offers exceptional thermal performance at
low pressures due to a unique 3.0 W/m-K
filler package and low-modulus resin
formulation. The enhanced material is
ideal for applications requiring low stress
on components and boards during
assembly. Gap Pad® HC 3.0 maintains a
conformable nature that allows for quick
recovery and excellent wet-out
characteristics, even to surfaces with high
roughness and/or topography.
Gap Pad® HC 3.0 is offered with natural
inherent tack on both sides of the material,
eliminating the need for thermally-
impeding adhesive layers. The top side
has minimal tack for ease of handling.
Gap Pad® HC 3.0 is supplied with
protective liners on both sides.

1) Young’s Modulus, calculated using 0.01 in/min. step rate of strain with a sample size of 0.79 inch2 after 5 minutes of
compression at 10% strain on a 1mm thickness material.
2) The ASTM D5470 test fixture was used. The recorded value includes interfacial thermal resistance. These values are
provided for reference only. Actual application performance is directly related to the surface roughness, flatness and
pressure applied.
3) Minimum value at 20 mil.
4) Thirty second delay value on Shore 00 hardness scale.
