NOTES: All properties are typical values based on roll averages. Contact DuPont to verify that properties listed meet your specific application. MD=Machine Direction CD=Cross Direction For all styles with antistat, the log of the electrical resistivity has a maximum roll average of 9.8 ohms/square (at 55% relative humidty, smooth and rough side). Values are based on preliminary specifications.

(a) Modified for specimen size.

(b) 7.15 psi, 0.625 inch diameter presser foot.

(c) Cut strip; CRE tensile tester, crosshead speed of 2 in/min and gauge length of 5 inches.

(d) 1.0in2 orifice size at 20 ounce cylinder weight.

All preliminary properties will be confirmed according to ISO 9000 specifications.
