Heat Shrink Tube

Heat-shrink tubing is a versatile protective sleeve made from radiation-crosslinked polyolefin or other specialized polymer materials. When heated, it shrinks radially to conform tightly to the substrate, providing electrical insulation, mechanical protection, environmental sealing, and stress relief.

KEY FEATURES

• Reliable Insulation
• Waterproof Sealing (Dual-Wall)
• Quick Installation
• Strong Adaptability
• Durable Protection

SPECIFICATIONS

• Product Composition:
• Outer Layer (Substrate): Radiation-crosslinked polyolefin, providing mechanical protection, insulation, and
