Product Labeling
A self-adhesive product label, with information content
similar to Figure 3, is located on the inside of the roll core
and the outside over-wrap of each roll. The label indicates
the product roll’s width and length in both English and
metric units.
Figure 3. Finished Product Roll Label
GMC: D13278258
Product: Nafion™ NC700
Width: 12 IN x Length: 328 FT
Width: 305 MM x Length: 100.0 M
Manufacture Date: 01/2019
• GMC is a product setup code specific to the thickness,
roll width, length, and other packaging features.
• Manufacture Date is the wide-stock roll’s slit date
(mm/yyyy).
Recommended Roll Storage Conditions
Unopened roll packages of Nafion™ PFSA membrane
should be stored in the original shipping box, out of
direct sunlight, in a climate-co
ntrolled environment
maintained at 10–30 °C (50–86 °F) and 30–70% RH.
Before opening the package, pre-co
ndition the membrane
roll to the processing area temperature for 24 hr.
o
nce opened and exposed to the environment, the
membrane will equilibrate to the ambient RH and change in
dimensions accordingly. Membrane order dimensions are
specified and measured at 23 °C (73 °F) and 50% RH.
Handling Practices
Ventilation should be provided for safe handling and
processing of Nafion™ PFSA membrane. The amount of
local exhaust necessary for processing Nafion™ PFSA
membrane at elevated temperatures will depend on the
combined factors of membrane quantity, temperature, and
exposure time.
