Description
Key Features:
Dual-Wall Co-Extrusion:
The robust dual-wall design combines a durable outer layer with a hot melt adhesive inner lining to provide optimal sealing and protection from moisture, contaminants, and other environmental factors.
UV Resistant:
Engineered to withstand prolonged exposure to UV light and outdoor elements, ensuring long-lasting performance in weather-exposed applications.
Flame Retardant:
Meets specific industry requirements for controlled flammability, making it ideal for safety-conscious applications in medium and high-voltage systems.
Semi-Rigid Design:
The semi-rigid construction offers a perfect balance of flexibility and mechanical strength, making it suitable for a wide range of installation environments.
Shrink Ratio 3:1:
The 3:1 shrink ratio allows the tubing to cover a wide range of cable sizes, reducing inventory requirements and simplifying installation processes.
High-Temperature Recovery:
Fully recovers at a minimum temperature of 120℃, ensuring a tight, reliable, and secure fit in all cable insulation and sealing applications.
Applications:
Cable Insulation and Sealing:
Perfect for medium and high-voltage cables in industries that require superior moisture protection, UV resistance, and mechanical durability.
Harsh Environmental Conditions:
Ideal for installations where UV exposure, mechanical stress, and moisture protection are crucial, such as outdoor or underground environments.
