What does ESD stand for and what is the difference between ESD and Conductive materials?

Most plastics are electric insulators and they have a tendency to accumulate static electric charges. This can cause damage to electronic components and assemblies.

ESD materials are produced by filling a plastic with a conductive material such as carbon black. This allows the static to dissipate preventing static build up.

 

Electrostatic Dissipative Material (ESD) is a material that has a surface resistivity between that of a conductor and an insulator, usually defined as between about 106 and 1012 O/.quadrature

Conductor is a material that has a surface resistivity less than about 105 O/.quadrature
Insulator is a material that has a surface resistivity greater than about 1013 O/.quadrature

Resistivity the inverse of electrical conductivity, is a measure of the resistance to the flow of an electric current and is measured either as a surface or a volume phenomenon. Surface resistivity is expressed in ohms per square (O/.quadrature.) and is measured at the surface of a material, usually at room temperature. Information detailing methods for quantifying surface resistivity is given in ASTM D257 and EOS/ESD S11.11.
