In nuclear power environments, cable protection systems must meet the highest standards of safety, reliability, and long-term performance. Extreme conditions such as radiation exposure, elevated temperatures, humidity, and strict fire safety requirements demand advanced material solutions.

To address these challenges, we have developed a dual-wall co-extruded flame retardant heat shrink tubing, specifically engineered for nuclear power applications. This article provides a technical overview of its structure, performance advantages, and key application scenarios.

Key Technical Advantages

1. Flame Retardancy for Critical Safety

○ Reduces fire propagation risk

○ Enhances overall system safety

2. Excellent Sealing Performance

○ Moisture-proof sealing

○ Resistance to dust and contaminants

○ Protection against corrosion

3. Mechanical Protection and Strain Relief

The outer layer ensures:

○ Abrasion resistance

○ Impact protection

4. Consistent Quality via Co-Extrusion

Compared to traditional adhesive-lined tubing, co-extrusion provides:

• Uniform adhesive distribution
• Stronger bonding between layers
• Improved long-term reliability

Challenges

• Extreme safety requirements
• Flame retardancy and low smoke requirements
• Long-term aging resistance
• Moisture and environmental sealing
• High reliability for critical systems

Datasheet

• Operating temperature: -55~90℃
• Shrink Ratio: 4:1
• Standard Color: Black, Inner Red.
• ROHS compliant
• Flame Retardant
