Structural Stability Cable Water Blocking Powder 9003-04-7 Water Blocking Gel

MACRO SORB® Superabsorbent Polymers (SAP) for the Cable Industry provide essential water ingress protection in demanding environments. When cable sheaths are compromised, the SAPs quickly absorb water, expand, and seal the damage, preventing further penetration and reducing the risk of electrical failures.

Designed for high-voltage, communication, and fiber optic cables, MACRO SORB® SAPs are integral to modern cable manufacturing. They offer reliable, cost-effective solutions to enhance cable durability and performance, meeting the growing demand for high-performance cables across industries.

Can be applied directly loose into the cable, especially in high-voltage cables, during the manufacturing process. The dosage depends on the cable structure and the desired water sealing.

MACRO SORB® SAP as the CABLE FILLING COMPOUNDS works in cable gels or jelly, providing water absorption, water retention, structural stability, and enhanced waterproofing capabilities for cables. For optimum protection of the cable against water ingress, cable fillers are applied either between the core wrap and the outer protective jacket (Cable Flood) or directly onto the cable core (Cable Filler).

MACRO SORB® SAP Polymers with a high swelling rate can be incorporated into water-blocking tapes, which are used to prevent water from spreading within the cable. Typically, this strip material is embedded inside the cable, and upon damage, it will quickly absorb water and expand, serving to seal the water source and prevent the spread of moisture.
