Narva Heat Shrink Dual Wall Black ID: 39mm Length: 1.2m

The Narva Heat Shrink Dual Wall Black ID: 39mm Length: 1.2m is a premium, high-performance heat shrink tubing designed to provide superior protection and insulation for a variety of electrical applications. Here are the key details and features of this product:

1. Size:

   • Inner Diameter (ID): 39mm (before shrinking).
   • Length: 1.2 meters (ideal for use on larger cables or multiple applications).

2. Dual Wall Construction:

   • Outer Wall: Made of a strong and flexible polyolefin material that offers excellent mechanical protection and resistance to abrasions, providing a durable outer layer.
   • Inner Wall: The inner layer features a thermoplastic adhesive that melts when heated, creating a strong seal around the wire or cable. This ensures that the tubing stays in place and offers added waterproofing and electrical insulation.

3. Shrink Ratio:

   • 3:1 Shrink Ratio: The tubing shrinks to approximately one-third of its original diameter when heated, ensuring a tight, secure fit around cables, connectors, or other components.

4. Temperature Range:

   • Shrink Temperature: Begins to shrink at approximately 90°C (194°F), achieving full shrinkage at higher temperatures.
   • Operating Temperature: This heat shrink tubing can withstand temperatures from -55°C to +125°C, making it suitable for both indoor and outdoor applications, and in harsh environments.

5. Durability:

   • Abrasion Resistance: The outer polyolefin layer provides excellent resistance to abrasion, making it ideal for use in environments where the tubing will be exposed to wear and tear.
   • Waterproofing: The inner adhesive layer creates a waterproof seal around the wire, ensuring it is protected from moisture and corrosion.
   • Chemical Resistance: The material is resistant to oils, solvents, and other chemicals, offering further protection in industrial or automotive environments.

6. Color:

   • Black: The black color is commonly used for a professional, neutral look and is often chosen for standard electrical wiring, automotive, and industrial applications.

Benefits:

• Superior Insulation: The dual-wall design provides a high level of insulation, with the adhesive inner layer helping to securely seal and protect cables from the elements.
• Waterproof and Chemical Resistant: The adhesive lining ensures a waterproof seal, while the outer polyolefin layer protects against chemicals, oils, and abrasions.
• High Durability: Resistant to wear, abrasion, and environmental damage, this tubing is perfect for use in rugged conditions.
• Easy to Apply: The tubing is easy to apply with a heat gun, and it will shrink to tightly fit over your wires or cables, providing a clean and professional finish.
• Versatile Use: Suitable for a wide range of applications, including automotive, marine, industrial, and electrical wiring.

Applications:

• Automotive Wiring: Ideal for use in automotive wiring, offering insulation and protection from abrasion and environmental damage.
• Marine Applications: Protects wiring and electrical components in marine environments where water, salt, and moisture are a concern.
• Electrical Systems: Perfect for protecting electrical wiring in any application, whether it's residential, commercial, or industrial.
• Industrial Equipment: Used to protect industrial wiring systems exposed to harsh conditions, oils, and chemicals.
• DIY Projects: Great for hobbyists or custom wiring projects where added protection is needed.
