*This page is about sodium polyacrylate for cables.
Sodium polyacrylate
Sodium polyacrylate also referred to as Slush Polymer has the capacity to absorb and retain liquid in large quantities relative to its own mass.
It is a white granular or powder solution material that can absorb liquid a hundred times its weight and when it does, it locks water firmly.
Uses for cables
For cables, sodium polyacrylate can be used as the water blocking material for
water blocking tapes,
water blocking ointment,
water blocking yarn.
