The Dual Wall Heat Shrink Tube is an essential product designed to provide superior insulation, protection, and sealing for electrical connections and components. This tubing is distinguished by its dual wall construction, which includes an inner adhesive lining that melts and flows upon heating to create a moisture-resistant and airtight seal. This makes the dual wall adhesive lined heat shrink tubing highly effective in preventing corrosion, environmental damage, and mechanical abrasion on wires, cables, and connectors.
One of the standout features of this product is its availability in convenient roll packaging. The roll format allows for easy handling, cutting, and application, making it ideal for both industrial and DIY projects. Users can customize the length of the tubing to fit specific needs, reducing waste and improving efficiency in various electrical insulation and protection applications.
The dielectric strength of this dual wall adhesive heat shrink tubing ranges between 600V and 1500V per millimeter, ensuring excellent electrical insulation performance. This high dielectric strength protects against electrical shorts, arc flashes, and other electrical hazards, making it suitable for use in demanding environments where electrical safety is paramount.
The tubing has a minimum shrink temperature of 80°C, which means it begins to shrink and conform tightly around the underlying substrate at relatively low heat levels. This characteristic allows for safe application without the risk of damaging sensitive components or insulation underneath. The heat shrink process activates the adhesive lining, which flows to form a robust, moisture-tight seal, enhancing the durability and reliability of the insulated connection.
With multiple shrink ratios available—2:1, 3:1, and 4:1—this dual wall adhesive lined heat shrink tubing offers versatility to accommodate a wide range of wire sizes and shapes. The 2:1 ratio allows the tubing to shrink to half its original diameter, while the 3:1 and 4:1 ratios provide even greater shrinkage, making it adaptable to irregular shapes and ensuring a snug fit on connectors and cables of varying dimensions. This flexibility simplifies inventory management and reduces the need for multiple tubing sizes.
In terms of mechanical properties, the tubing has a tensile strength of 10.4 MPa, which guarantees excellent resistance to pulling forces, abrasion, and environmental wear. This strength ensures that once applied, the tubing will maintain its integrity under mechanical stress, providing long-lasting protection for the electrical components it encases.
The dual wall adhesive lined heat shrink tubing is widely used in automotive, aerospace, telecommunications, marine, and general electrical industries. Its ability to provide both insulation and a sealed protective barrier makes it invaluable for safeguarding connections against moisture, dust, chemicals, and other contaminants.
Overall, this product combines ease of use, robust electrical and mechanical properties, and reliable environmental protection, making the dual wall adhesive heat shrink tubing an excellent choice for professionals and hobbyists alike. Whether used for repairing wires, insulating splices, or protecting terminal ends, the dual wall adhesive lined heat shrink tubing delivers dependable performance and peace of mind in any electrical application.
