Electrostatic discharge materials

Electrostatic discharge materials (ESD materials) are plastics that reduce static electricity to protect against damage to electrostatic-sensitive devices (ESD) or to prevent the accidental ignition of flammable liquids or gases.

ESD materials are generally subdivided into categories with related properties: Anti-Static, Conductive, and Dissipative.

[1] Note that the sheet resistance quoted above depends on the thickness of the layer of material, and the value is the resistance of a square of the material for a current flowing from one edge to the opposite edge.

Insulative materials prevent or limit the flow of electrons across their surface or through their volume.

Static charges remain in place on these materials for a very long time.
