MACRO SORB ® Cable Water Blocking Polymer Strong Absorption Under Pressure Good Expansion Height

Introduction of MACRO SORB® Cable Water Blocking Polymer

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.

MACRO SORB® Cable Water Blocking Polymer Applications

Direct Incorporation Into Cables

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.

Cable Filling Compounds(Gels Or Jelly)

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).

Water Blocking Tapes

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.

Additionally, we offer customized services to provide tailored solutions that cater to our customers' specific needs.

FAQ

1. What is water blocking powder?

Water-Blocking Powder is a kind of super absorbent polymer made of sodium polyacrylate. This kind of water blocking powder will be swelling to block the gap and preventing further water penetration.

2. What is water swellable tape in cable?

Water-swellable tape, also known as water-blocking tape or water-swellable polymer tape, is a material used in the construction of cables to prevent water ingress.Using super absorbent polymers (SAP) gives these tapes premium performance during the critical first minute of response to water. It is typically applied in the cable's core or around the cable's components to provide a barrier against moisture and water penetration.

3. What is the ingredient of SOCO® cable water blocking polymer?

SOCO cable water blocking polymer is one kind of super absorbent polymer which is sodium polyacrylate. It has better water absorbent capacity and harmless.

4. How should sodium polyacrylate be stored?

Store in a cool, dry, well-ventilated, locked store room away from incompatible materials. Use ventilation to keep airborne concentrations below exposure limits.
