- 1) Thirty second delay value Shore 00 hardness scale. 

Gap Pad 2500 is a thermally conductive, electrically insulating, un-reinforced gap filling material. 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 characteristics to surfaces 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._
