Conductive & Anti-Static Compounds

Conductive thermoplastic compounds offer reliability and value for applications that require dissipation of static and/or protection from electrostatic discharge (ESD).

Specialty compounds can be tailored to span the surface resistivity spectrum from 100 to 1012 ohm/sq. and formulated for injection molding or extrusion processing.

Multiple technologies are available to impart conductive properties into thermoplastic resins. Each offers different approaches to providing the exact degree of conductivity required for your application, whether anti-static, static dissipative, ESD protection, conductive, or EMI/RFI shielding.

In all-polymeric materials conductive polymers (IDP or ICP) are alloyed with host resins, for others conductive particulate or fibers are combined with a base polymer to form a conductive matrix.

Conductive thermoplastics compounds have a number of advantages over metals or surfactant coatings. Finished parts are lighter in weight, easier to handle, and less costly to ship. Their fabrication is usually easier and less expensive due to the elimination of secondary processes, and they are subject to less denting, chipping and scratching.

Black is not your only choice, many conductive compounds can be colored for identification or aesthetic purposes, eliminating time-consuming secondary color operations, some permanently anti-static grades offer transparency.
