TEST METHOD Visual Reinforcement Carrier ELECTRICAL Dielectric Breakdown Voltage (Vac) 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. METRIC VALUE Light Brown NA = Selected standard option.
