45mm Dual-Wall Heat Shrink Tubing

This 45mm Dual-Wall Heat Shrink Tubing provides robust insulation and a watertight seal for medium-to-large diameter cable assemblies. With a 2:1 shrink ratio, it securely conforms to cables, connectors, and splices—offering strong pullout resistance, environmental protection, and mechanical durability in demanding applications.

Key Features:

• 2:1 Shrink Ratio:
  Shrinks to 50% of its original diameter when heated—ensuring a tight, secure wrap around electrical joints and cable terminations.

• Dual-Wall Construction with Thermoplastic Lining:
  The inner adhesive layer melts during heat application, bonding to the cable surface. On cooling, it creates a waterproof and vibration-resistant seal.

• Heavy-Duty Protection:
  Provides insulation, moisture resistance, and enhanced mechanical strength, ideal for high-stress cable junctions and assemblies.

• Stress Relief in Bending Zones:
  Especially suited for coaxial and signal cables where tight bends or frequent motion occur.

Technical Specifications:

• Nominal Diameter (Before Shrink): 45mm

• Shrink Ratio: 2:1

• Material: Cross-linked polyolefin (outer), heat-activated thermoplastic adhesive (inner)

• Function: Waterproofing, strain relief, insulation, and anti-slip protection

• Application Temperature: Begins at ~70°C, full recovery at ~110°C
