Gap Pad

2500S20

Highly Confor mable ,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” ther mal resistance at

ultr a-low pressures

• Ultra confor mable ,“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 r ated at a thermal

conductivity of 2.4 W/m-K.The material is a

filled-polymer mater ial yielding extremely soft,

elastic char acteristics.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 topogr aphy.

Gap Pad 2500S20 is offered with inherent

natur al tack on both sides of the mater ial

allowing for stick-in-place character istics during

application assembly.The mater ial is supplied

with protective liner s 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 processor s and heat sinks

• Between graphics chips and heat sinks

• DVD and CDROM electronics cooling

• Areas where heat needs to be tr ansferred to a frame , chassis or other type of heat spreader

Configurations Available:

• Sheet form and die-cut parts
