What type of ESD protective material includes metal and carbon-impregnated plastics?

The correct type of ESD protective material that includes metal and carbon-impregnated plastics is conductive ESD protective material. This type of material is specifically designed to dissipate static electricity and prevent electrostatic discharge, which can damage sensitive electronic components.

Conductive ESD protective materials have the ability to conduct electricity and provide a continuous path to ground, thereby safely redirecting the static charges away from sensitive devices. The inclusion of metals and carbon in these materials enhances their conductive properties, making them highly effective in environments where static discharge is a concern.

In contrast, antistatic ESD protective materials are primarily designed to reduce the buildup of static electricity but do not conduct electricity as effectively as conductive materials. Standard plastic ESD materials do not typically have the same level of conductivity and are often used for lighter protection against static. Hybrid ESD-protective bags may combine different materials but may not exclusively include the metal and carbon components found in conductive materials.
