|Ohms Per Square||Material||Description|
|103 to 105e||Conductive||No initial charge. Provides path for charge to bleed off. Typically black color.|
|105 to 109||Dissipative||No or low initial charge. Prevents discharge to or from human contact|
|109 to 1012||Anti-Static||Initial charges are suppressed.|
|1013||Insulative||Insulators and Base Polymers. Not an ESD material|
Anti-static materials are generally referred to as any material which inhibits triboelectric charging. This kind of charging is the buildup of an electric charge by the rubbing or contact with another material.
