摘要： A net-shape molded elastomeric gasket for dissipating heat and providing electro-magnetic interference (EMI) shielding for an electronic device is formed by loading a base elastomeric matrix material with thermally conductive filler and EMI reflective metallic filler and injecting the mixture into a mold cavity. The gasket of the present invention provides superior sealing between the case sections of an electronic device by shielding the device from EMI infiltration along the seam between the sections. In addition, the gasket of the present invention is in thermal communication with the case sections of the electronic device to provide thermal transfer and dissipation between the separate parts of the device.

摘要： A thermally conductive and electromagnetic interference and radio frequency reflective polymer composition and a method for creating the same is disclosed. Thermally conductive filler material is coated with a thermally conductive and electromagnetic interference and radio frequency reflective coating material and mixed with a base polymer matrix. The mixture is molded into the desired shape. The electromagnetic interference and radio frequency reflective coating material prevents the absorption and transfer of EMI and RF waves through the filler material thus resulting in an EMI and RF reflective composition.
