ESD MATERIALS

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.

 Description

 

No initial charge. Provides path for  charge to  bleed off. Typically black  color.

 

 No or low initial charge. Prevents  discharge to or from human  contact  Initial charges  are   suppressed.  Insulators and Base  Polymers. Not an ESD  material

 


Conductive


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


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


Anti-Static


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


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.
