Gap Pad 2500 is a filled-polymer material yielding an elastic polymer that allows for easy handling and converting without the need for reinforcement.These properties also allow for good wet-out and interfacing char- acteristics to surf aces with roughness and/or topography. All these characteristics make this material ideal for applications using either clip or screw-mounted assemblies. Gap Pad 2500 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. Note: Resultant thickness is defined as the final gap thickness of the application. Typical Applications Include:  Multiple heat-generating components to a common heat sink  Graphics chips to heat sinks  Processors to heat sinks  Mass storage drives  Wireline / wireless communications hardware Configurations Available:  Sheet form and die-cut parts Building a Part Number Standard Options Section A Section B Section C Section D Section E NA = Selected standard option.
