Superabsorbent polymers (SAP) for the cable industry

The cable industry faces the challenge that defective cables can result in costly repairs, especially for complex installations.

LEVACO's superabsorbers quickly and reliably protect the conductor/strand inside the cable in case of water ingress, if the cable sheath is damaged, and maintain the functionality of the cable. In the event of damage and water penetration, our products quickly absorb the water, thereby expand and seal cavities along the cable to prevent further water intrusion.

For the cable industry and its suppliers, LEVACO offers a wide range of water-swellable, water-absorbing and water-blocking polymers, so-called "superabsorbents" (SAP). Nowadays, these SAP are incorporated in almost all types of cables, such as high-voltage cables, communication or optic fiber cables.

The product range includes

  • Superabsorbent polymers (powder) DEFOSORB®
    - for direct incorporation into the cable
    - for cable filling compounds
    - for water-swellable tapes

  • Superabsorbent polymers (liquid) DEFOPOL
    - for yarn
