Water-blocking Powder
1. Definition
It is a kind of macromolecule water absorbent resin made of sodium polyacrylate, With unique body structure and
excellent hydrophilic group, it has the characteristics of large water absorption, strong water retention and high
expansion rate.
2. Application
It owns excellent property of water absorption and provides good insulation protection to prevent moisture erosion
damager. The water blocking powder is added during the procession of conductor stranding, When the water enter the
conductor, the water blocking water will be swelling to block the gap and preventing further water penetration.
3. Package
In ton bags. Ton bag in pallet .Max. 20Tons/20FT container.
