The Dual Wall Heat Shrink Tubing is designed for large-diameter cable insulation, providing secure and uniform sealing for cables of various sizes. It is commonly used in power cable terminations, splices, and industrial wiring, offering high-strength insulation and mechanical protection.
The thick polyolefin outer layer provides abrasion resistance, impact protection, and UV shielding, while the inner adhesive lining ensures a moisture-resistant, leak-proof bond, preventing failures in humid or submerged environments.
