Gap Pad
®
3000S30
Ther mally Conductive, Reinforced,Soft “S-Class” Gap Filling Mater ial
Gap Pad ®: U.S.Patent 5,679,457 and others
Features and Benefits
• Thermal conductivity: 3.0 W/m-K
• Low “S-Class” ther mal resistance at very
low pressures
• Highly conformable,“S-Class” softness
• Designed for low-stress applications
• Fiberglass reinforced for puncture , shear
and tear resistance
Gap Pad 3000S30 is a soft gap filling material
rated at a thermal conductivity of 3 W/m-K.
The mater ial offer s exceptional ther mal
performance at low pressures due to an all-
new 3 W/m-K filler package and low-modulus
resin formulation.It is reinforced to enhance
material handling, puncture , shear and tear
resistance . It is well suited for high perfor-
mance , low-stress applications that typically
use fixed standoff or clip mounting. Gap Pad
3000S30 maintains a conformable yet elastic
nature that allows for excellent interfacing
and wet-out character istics, even to surfaces
with high roughness and/or topography.
Gap Pad 3000S30 is offered with natural
inherent tack on both sides of the material,
eliminating the need for thermally-impeding
adhesive layers.The material’s natural inherent
tack allows for stick-in-place character istics
dur ing assembly.Gap Pad 3000S30 is supplied
with protective liners on both sides.The top
side has reduced tack for ease of handling.
Typical Applications:
• Processor s • Notebook computer s
• Server S-RAMs • BGA packages
• Mass storage drives • Power conversion
• Wireline / wireless communications hardware
Configurations Available:
• Sheet form and die-cut parts available
