Sodium Polyacrylate for Cable Applications


Sodium polyacrylate, also known as slush polymer, is highly efficient in absorbing and retaining large quantities of liquids relative to its own mass. This white granular or powder material effectively absorbs water, locking it securely in place.

Applications in Cables

In the cable industry, sodium polyacrylate serves as an excellent water-blocking material for:

  • Water-blocking tapes
  • Water-blocking ointments
  • Water-blocking yarn

Key Technical Specifications

  • High liquid absorption capacity: Absorbs liquid up to a hundred times its weight
  • Effective water locking capability: Ensures water is securely trapped

This versatile material plays a crucial role in protecting cables from water ingress, thereby enhancing their durability and performance in various environmental conditions.
