Product Description

Product information: 

The Dual Wall Heat Shrink Tube is a high-performance staple for electrical and mechanical applications, delivering premium insulation, robust protection, and long-lasting durability—all at an attractive price point without compromising quality.
Crafted from durable Polyolefin (a material renowned for reliability), this dual-wall adhesive-lined tubing stands out with its core advantage: an inner adhesive layer that melts and bonds tightly to substrates when heated, forming a secure, moisture-resistant seal. Ideal for environments where defense against moisture, dust, and chemicals is critical, it’s a cost-effective yet high-quality solution for professional and DIY projects alike.
Boasting flexible shrink ratios (2:1; 3:1; 4:1), it conforms seamlessly to irregular shapes and connectors—made even easier by its 400% elongation rate, which lets it stretch without breaking, maintaining a consistent seal under vibration or movement. Its mechanical strength is equally impressive: with a tensile strength of 10.4 MPa, it resists abrasion, impact, and physical stress for long-term durability.
Safety and versatility are non-negotiable here: it holds a UL224 VW-1 flammability rating (meeting strict fire-resistance standards) and operates reliably across a wide temperature range of -55°C to 125°C—perfect for extreme cold, high-heat, or fluctuating environments (think outdoor setups, industrial machinery, or automotive wiring). Electrical performance is top-tier too, with a dielectric strength of 600V-15kV/mm ensuring robust insulation.
Installation is hassle-free: simply cut to length with scissors or a knife, then apply heat to activate the 125°C full-shrink temperature—the adhesive bonds quickly, saving labor time. Available in a spectrum of colors (Black, Red, Yellow, Blue, White, Green, Grey, Pink), it suits both functional and color-coding needs.
In short, this dual-wall heat shrink tube pairs unbeatable value with professional-grade performance: UL-certified safety, all-weather reliability, rugged durability, and user-friendly design. For electrical wiring, automotive harnesses, or industrial equipment, it delivers peace of mind, longevity, and protection—all at a price that’s easy to justify.
