Electrostatic Dissipative Polyester Wipes
Polynit-Z wipe is constructed using conductive yarns within the polyester interlock knit that features an unidirectional conductive pattern. It is a very clean static dissipative wipe that is well suited for applications sensitive to electrostatic discharge. The average surface resistivity is 3.5 x 1019 ohms/sq.
Polynit-Z wipes have laser-cut edges which seal fibers at the wipe's edge. The wipes are ideal for cleaning the interior surface of process tools and other equipment.
These wipes meet the requirements of USP<797> and IEST-CC-RP004.4 for "non-shedding, low-lint, lint-free wipes."
