Electrostatic discharge materials (ESD materials)

Electrostatic discharge materials (ESD materials) are plastics that reduce static electricity to protect electrostatic-sensitive devices (ESD) or contain flammable liquids or gases.


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


Conductive materials have a low electrical resistance, thus electrons flow easily across the surface or through these materials. Charges go to ground or to another conductive object that the material contacts.


Dissipative materials allow the charges to flow to ground more slowly in a more controlled manner than with conductive materials.


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.


Insulative materials prevent or limit the flow of electrons across their surface or through their volume. Insulative materials have a high electrical resistance and are difficult to ground, thus are not ESD materials. Static charges remain in place on these materials for a very long time.
