During their service life, wires and electrical cables, can be exposed to a variety of detrimental environmental conditions. Beyond the effects of typical light and heat exposure, other environmental conditions can negatively impact the physical properties and performance of a wire or cable during its end-use. Microorganisms can attack polymers that are typically used in wire and cable jacketing formulations and other components of cable construction, such as filling compounds, resulting in a shortening of their service life by causing premature deterioration and discoloration. This paper will review a new range of antimicrobial additives developed, as active ingredients for use in a variety of polymer applications, to meet the fast growing market needs for biocides that can provide antimicrobial surface effects, beyond typical polymer protection.
