In electrical, automotive, marine, and industrial applications, protecting wires and cables from moisture, corrosion, and mechanical damage is essential for long-term reliability. Dual Wall Heat Shrink Tube is an advanced heat shrink solution that combines electrical insulation with strong environmental sealing performance.
Unlike standard single-wall heat shrink tubing, Dual Wall HeatShrink Tube features a dual-layer structure with an outer polyolefin layer and an inner adhesive layer. When heated, the inner adhesive melts and creates a waterproof seal around cables, terminals, and connectors.
As a professional Dual Wall Heat Shrink Tube Manufacturer and Dual Wall Heat Shrink Tube Supplier, we provide high-quality heat shrink solutions designed for demanding industrial applications.
What Is Dual Wall Heat Shrink Tube?
Dual Wall Heat Shrink Tube is a type of adhesive-lined heat shrink tubing designed to provide both insulation and sealing protection.
It consists of two layers:
Outer Layer
The outer layer is usually made of cross-linked polyolefin material, providing:
Mechanical protection
Abrasion resistance
Electrical insulation
Heat resistance
Inner Layer
The inner adhesive layer provides:
Waterproof sealing
Moisture protection
Corrosion resistance
Strong bonding performance
When heated, the tube shrinks while the adhesive flows and fills gaps, creating a tight protective seal.
Features of Dual Wall Heatshrink Tube
