Wiman can engineer many types of plastic films to deliver a range of electrical properties from anti-static to highly conductive. Properties are permanent and non-sloughing:
Anti-Static plastics deliver a surface resistivity of 1010 to 1012 ohm/sq. These films provide a decay of static charge, from hundredths of a second to several seconds, preventing accumulations that could otherwise lead to discharge or the initiation of other nearby electrical events. Wiman produces films in this range. Available in translucent, colors, and black.
Static Dissipative plastics deliver a surface resistivity of 106 to 1012 ohm/sq. These films allow for the dissipation or decay of electrical charges at a much faster rate than anti-static materials, generally within milliseconds. Measured resistance is uniform and usually strong. Wiman films cover the 109 to 1012 portion of this range. Available in translucent, colors, and black.
Conductive plastics deliver a surface resistivity of 101 to 106 ohm/sq. Decay rates measured in nanoseconds are instant enough to provide a ground pathway and bleed off stronger electrical charges. Wiman films cover the 103 to 106 portion of this range. Available in black only.
