Typically crosslinked acrylates, superabsorbent polymers (SAP) absorb and retain
at least 200x their own weight
DefinitionIntroduction
3
Water diffuses into the SAP particle by:
Capillary action Osmotic pressure
AbsorptionIntroduction
4
The dry SAP changes into a flexible but resistant hydrogel
by absorbing water
Swollen SAP
Swelling and BlockingIntroduction
Dry SAP
5
Absorption Phase
Incoming water is absorbed and retained so its free flow is hindered. A fast and high absorption is beneficial at this step.
Blocking Phase
Swollen SAP has to be impermeable to stop the water-transport from gel-particle to gel-particle. Gel-strength and gel-stability are more important than capacity or speed.
Dry SAP Impermeable stable hydrogel
Steps of SealingIntroduction
6
The permeability of SAP determines how water is transported in a layer of swollen SAP
The water transport happens through microscopic channels between the hydrogel particles
The permeability is mainly influenced by:
Shape (form and surface) of SAP particles Gel strength (rheology/viscosity) of SAP
PermeabilityIntroduction
7
Hydrated gel strength is very important:
A high and fast absorbing SAP does not provide good sealing properties for the expected life of the cable.
Swollen SAP creating an impermeable hydrogel, with excellent gel-stability is required for good water-blocking properties

Streamlined Cable Manufacturing Process
Faster line speeds / cleaner process Usage volume is a fraction of what it replaces
(i.e. filling / flooding compounds)
Improved Cable Installation
Smaller diameter Lighter weight Easier cable pulls both aerial and underground / conduit
Significant Reduction in Cable Prep / Splice Time
Lowers cost of initial installation Reduces emergency cable outage / restoration time
Cablers / Installers/ End UsersBenefits
19
Improves Cable Life Cycle
Effective sealing of defects localizing water damage Replacement of gel eliminates damage due to oxidation Insoluble x-linked polymers insure long term stability
Environmentally-friendly / neutral
SAP is non-toxic and can be placed in land-fills SAP is used in agricultural applications for soil amendment
