𝗙𝗿𝗼𝗺 𝗘𝗦𝗗 𝗣𝗿𝗼𝘁𝗲𝗰𝘁𝗶𝗼𝗻 𝘁𝗼 𝗘𝗠𝗜 𝗦𝗵𝗶𝗲𝗹𝗱𝗶𝗻𝗴: 𝗧𝗵𝗲 𝗩𝗲𝗿𝘀𝗮𝘁𝗶𝗹𝗶𝘁𝘆 𝗼𝗳 𝗚𝗿𝗮𝗽𝗵𝗲𝗻𝗲 𝗠𝗮𝘁𝗲𝗿𝗶𝗮𝗹𝘀

In electronics manufacturing and packaging, materials are often classified by their 𝗲𝗹𝗲𝗰𝘁𝗿𝗶𝗰𝗮𝗹 𝗯𝗲𝗵𝗮𝘃𝗶𝗼𝘂𝗿: 𝗶𝗻𝘀𝘂𝗹𝗮𝘁𝗶𝗻𝗴, 𝗱𝗶𝘀𝘀𝗶𝗽𝗮𝘁𝗶𝘃𝗲, 𝗼𝗿 𝗰𝗼𝗻𝗱𝘂𝗰𝘁𝗶𝘃𝗲. These categories exist because different problems require different solutions.

𝗜𝗻𝘀𝘂𝗹𝗮𝘁𝗶𝗻𝗴 materials block current entirely. 𝗖𝗼𝗻𝗱𝘂𝗰𝘁𝗶𝘃𝗲 materials allow it to flow freely. 𝗗𝗶𝘀𝘀𝗶𝗽𝗮𝘁𝗶𝘃𝗲 materials (sometimes called static-dissipative) sit in between: they allow charge to drain away slowly and in a controlled manner, preventing the sudden discharge events that can damage sensitive components.

𝗚𝗿𝗮𝗽𝗵𝗲𝗻𝗲-𝗯𝗮𝘀𝗲𝗱 𝗺𝗮𝘁𝗲𝗿𝗶𝗮𝗹𝘀 𝗰𝗮𝗻 𝗯𝗲 𝗳𝗼𝗿𝗺𝘂𝗹𝗮𝘁𝗲𝗱 𝘁𝗼 𝗼𝗽𝗲𝗿𝗮𝘁𝗲 𝗮𝗰𝗿𝗼𝘀𝘀 𝘁𝗵𝗶𝘀 𝗿𝗮𝗻𝗴𝗲. At lower loading levels, the resulting compound may be dissipative, and useful for ESD-safe packaging, trays, or enclosures. At higher loading levels, with a well-dispersed conductive network, the material becomes suitable for EMI shielding.

The distinction matters for specification. A material described as "conductive" covers a very wide range of actual resistivity values, and the right value depends entirely on the function the material needs to perform.
