Product Description

Product Name: 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.
