Gap Pad 2500S20
Highly Conformable,Thermally Conductive, Reinforced “S-Class” Gap Filling Material
Gap Pad
: U.S. Patent 5,679,457 and others
Features and Benefits
Thermal conductivity: 2.4 W/m-K
Low “S-Class” thermal resistance at
ultra-low pressures
Ultra conformable, “gel-like” modulus
Designed for low-stress applications
Fiberglass reinforced for puncture, shear
and tear resistance
Gap Pad 2500S20 is a thermally conductive,
reinforced material rated at a thermal
conductivity of 2.4 W/m-K.The material is a
filled-polymer material yielding extremely soft,
elastic characteristics.The material is reinforced
to provide easy handling, converting, added
electrical isolation and tear resistance. Gap
Pad 2500S20 is well suited for low-pressure
applications that typically use fixed standoff or
clip mounting.The material maintains a
conformable, yet elastic nature that allows for
excellent interfacing and wet-out
characteristics, even to surfaces with high
roughness and/or topography.
Gap Pad 2500S20 is offered with inherent
natural tack on both sides of the material
allowing for stick-in-place characteristics during
application assembly.The material is supplied
with protective liners on both sides.The top
side has reduced tack for ease of handling.
Note: Resultant thickness is defined as the final gap
thickness of the application.
Typical Applications
Between processors and heat sinks
Between graphics chips and heat sinks
DVD and CDROM electronics cooling
Areas where heat needs to be transferred to a frame, chassis or other type of heat spreader
