Product Description:
ZIRFON
®
PERL is a high quality separator membrane for use in alkaline water electrolysis systems.
It allows for highly efficient electrolysis cell operation, and is very durable, allowing for many
years of operation under normal conditions.
ZIRFON
®
PERL can be considered as a replacement material for chrysotile asbestos and PPS
cloth, with far superior characteristics over both.

Composition:
ZIRFON
®
PERL consists of an open mesh polymer fabric, which is symmetrically coated with a
mixture of a polymer and zirconium oxide. It has a controlled pore size.
￿
Major features:
￿
Permanently hydrophilic, perfect wettable in water and most common electrolytes.
￿
Dimensionally stable (no shrinkage effects)
￿
Very robust (always reinforced with a fabric)
￿
Stable in strong alkaline
￿
Availability for different application temperatures
￿
Low ionic resistance, enables electrolysis at high current densities
￿
Symmetrical internal pore structure
￿
Double safety by double skinlayer
￿
Thickness upon request

Storage:
AGFA’s Zirfon® Perl separators are shipped with full moisture content.
In order to maintain the moisture-content as high as possible, AGFA recommends to keep the original
packingbags closed during storage in a cool place out of the sun.
Storage in a refrigerator is not necessary.
Keep the separatorsheets humid throughout the whole assembling process to ensure optimal
characteristics.

Humidifying:
It is always possible to humidify the separators with demineralizeddemineralizeddemineralizeddemineralized water, either by immersion
in a small bath, or by making use of a soft handspray gun.
￿
Dimensions and cutting:
Separatorfoil can be delivered in rolls up to 1,6m width, for the customer to cut down to application-
size, or can also be delivered in rectangle sheets.
Unwrap the separatorfoil according the needs, and cut it down to smaller sizes. Re-pack the rest to
avoid drying-out. Store for later use.
