4:1 High shrink ratio dual wall heat shrink tube electrical waterproof industrial black , red , yellow , clear

Product Description:

The Dual Wall Heat Shrink Tube is a versatile and reliable solution designed to provide superior insulation and protection for electrical connections, wires, and cables. Manufactured from high-quality polyolefin material, this tubing offers excellent durability, flexibility, and resistance to environmental factors, making it an essential component in various electrical, automotive, and industrial applications.

One of the standout features of this product is its dual wall construction. Also known as dual wall adhesive heat shrink tubing or double wall heat shrink tubing, it consists of an outer polyolefin layer and an inner adhesive lining. When heated, the tubing shrinks to tightly conform to the shape of the underlying substrate, while the inner adhesive melts and forms a strong, moisture-resistant seal. This combination ensures enhanced mechanical protection, electrical insulation, and resistance to corrosion, moisture, and abrasion, which are critical for maintaining the integrity and longevity of wiring systems.

The tubing is available in a variety of vibrant colors including Black, Red, Yellow, Blue, White, Green, Grey, and Pink. This wide color range allows for easy color coding, identification, and organization of wires and cables, which is particularly useful in complex electrical systems or environments where quick visual identification is necessary.

The Dual Wall Heat Shrink Tube offers impressive mechanical properties, including a tensile strength of 10.4MPa. This high tensile strength ensures the tubing can withstand significant stress and strain during installation and operation without tearing or breaking, thus providing reliable protection over time. Additionally, it exhibits a shrink ratio of 2:1, 3:1, and even 4:1, offering flexibility in fitting a range of wire diameters and shapes. The tubing’s ability to shrink significantly while maintaining its structural integrity makes it adaptable to various applications, from small connectors to larger cable assemblies.

Installation is straightforward and efficient, requiring only a minimum shrink temperature of 80℃. This relatively low shrink temperature allows for safe and quick application using standard heat guns or other heat sources, minimizing the risk of damage to sensitive components or insulation during the shrinking process. The ease of installation combined with the strong adhesive lining makes the dual wall adhesive lined heat shrink tubing an ideal choice for both professional technicians and DIY enthusiasts.

In addition to electrical insulation and mechanical protection, this tubing also provides excellent resistance to chemicals, UV radiation, and abrasion, which enhances its suitability for harsh environments. Whether used in automotive wiring harnesses, marine electronics, aerospace applications, or general electrical maintenance, this heat shrink tubing ensures reliable performance and long-lasting protection against environmental challenges.

Overall, the Dual Wall Heat Shrink Tube stands out as a high-performance product that combines the benefits of sturdy polyolefin material, a strong adhesive lining, and a versatile range of shrink ratios and colors. It is engineered to meet the demands of modern electrical insulation and protection needs, making it an indispensable tool for professionals seeking durable, efficient, and visually organized solutions. Whether you need to protect, insulate, or seal electrical connections, this dual wall heat shrink tubing provides an excellent balance of strength, flexibility, and ease of use.
