The usual dimensions of pad rolls are 3 (76 mm) I.D. x 6 (152 mm) or 9 (230 mm) outside diameter (O.D.) for widths up to 4 (102 mm). In Luxembourg, 152 mm, 180 mm, 203 mm, and 240 mm O.D. rolls are available. For wider rolls, the usual dimensions are 6 (152 mm) I.D. x 9-1/2 (240 mm) or 11 (280 mm) O.D. For Universal and Step-Pac(TM) rolls, the dimensions are 3 (76 mm) I.D. x 6 (152 mm), 8 (203 mm), or 12 (305 mm) O.D. If these dimensions are not suitable, information on other options is available from your DuPont High Performance Films technical or customer service representative.

Test Method
The percent shrinkage obtained for either the MD or TD by using the average of three measurements in either direction before and after conditioning. Temperature exposure 200C ?C (392F ?.6F) for 1 hr. Measurements must be made at the same temperature and humidity conditions before and after conditioning. To ensure sample/ambient equilibrium before and after conditioning, specimens should be exposed for 3 hr.
