Cable-Grade Water-Blocking Polymer Powder – Structural Integrity Formula

Cable-Grade Water-Blocking Polymer Powder

Our Cable-Grade Water-Blocking Polymer Powder is a high-performance superabsorbent material specifically engineered to prevent water ingress in power and communication cables. Upon contact with moisture, the polymer rapidly swells into a stable gel, effectively blocking water migration along the cable core and between layers.

Formulated with excellent structural integrity, this powder ensures long-term protection, reducing the risk of cable failure caused by water damage. It features fast absorption speed, high expansion capacity, and thermal stability, making it ideal for applications in fiber optic, submarine, and underground cables.

Key Features:

• Rapid swelling and gel formation upon contact with water

• Superior water-blocking efficiency

• Excellent thermal and chemical stability

• Compatible with a wide range of cable insulation materials

• CAS No. 9003-04-7

This product is a reliable and cost-effective solution for enhancing the durability and service life of modern cable systems.

FAQ

Q1: What is Cable-Grade Water-Blocking Polymer Powder used for?

A: It is primarily used in power and communication cables to prevent water penetration. When exposed to moisture, the powder rapidly swells into a gel, creating a water-tight barrier that protects cable integrity.

Q2: How does it work?

A: The powder is composed of superabsorbent polymers that absorb water and expand to form a stable gel. This gel blocks the flow of water along the cable, preventing damage from moisture migration.

Q3: Is it compatible with all cable types?

A: Yes, the product is designed to be compatible with various cable constructions, including fiber optic, underground, submarine, and other moisture-sensitive cables.

Q4: What are the key benefits of using this powder?

A:

• Rapid water absorption and swelling

• Long-lasting gel stability

• High thermal and chemical resistance

• Easy to apply during cable manufacturing

• Enhances cable lifespan and performance

Q5: What is the chemical composition?

A: The powder is based on a crosslinked sodium polyacrylate polymer, commonly identified by CAS No. 9003-04-7.

Q6: Is the powder safe to handle?

A: Yes. It is non-toxic, non-corrosive, and safe to handle with standard protective equipment. Detailed safety guidelines are provided in the product’s MSDS.

Q7: How should it be stored?

A: Store in a cool, dry place away from moisture. Ensure the container is tightly sealed to prevent premature swelling.
