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.
