November 24, 2022

*This article is about super absorbent polymer for plants, potassium polyacrylate, Ag-SAP, water-retaining agent.

SOCO Super absorbent polymer (SAP) is an important water-blocking material.
It can absorb quickly the permeated water when the outer layer of the cable is broken.

Advantages of SOCO super absorbent polymer for water-blocking yarn/tape

  • High absorbent speed;
  • It's neutral when SOCO max with ointment (which can protect the metal in cable).
