摘要:
An article and process are described. The article includes a conductive heat-recoverable composite shield or a conductive heat-recovered composite shield formed from a conductive heat-recoverable composite shield. The conductive composite shield and/or the conductive heat-recovered composite shield formed from a conductive heat-recoverable composite shield comprises a non-conductive matrix and conductive particles within the non-conductive matrix. The article has a resistivity of less than 0.05 ohm·cm. A process of producing the conductive heat-recovered composite shield includes extruding the conductive heat-recoverable composite shield and heating the conductive heat-recoverable composite shield thereby forming the conductive heat-recovered composite shield.
摘要:
A composite formulation and electrical component are disclosed. The composite formulation includes a polymer matrix having at least 15% crystallinity and process-aid-treated copper-containing particles blended with the polymer matrix including higher aspect ratio particles and lower aspect ratio particles. The higher ratio particles and the lower ratio particles produce a decreased percolation threshold for the composite formulation when processed by extrusion or molding, the decreased percolation threshold being compared to a similar composition that fails to include the first particle and the second particles. The electrical component includes a composite product produced from the composite formulation and is selected from the group consisting of an antenna, electromagnetic interference shielding device, a connector housing, and combinations thereof.
