Abstract: The present disclosure provides a compressible gasket, an electronic product comprising the compressible gasket and a method for preparing the compressible gasket. The compressible gasket of the present disclosure comprises an open-cell foam matrix and a filling medium which fills and is cured in the open cells of the open-cell foam, the filling medium comprising a curable adhesive and one or more types of micrometer particles dispersed therein. The one or more types of micrometer particles comprise at least one of thermally conductive micrometer particles and thermally and electrically conductive micrometer particles, and optionally comprise at least one of flame retardant micrometer particles, electrically conductive micrometer particles and electromagnetic wave absorption micrometer particles. The compressible gasket of the present invention can provide shock and vibration absorption and sealing functions and also meet requirements on system thermal management design and/or electromagnetic compatibility design.
