Single-wall tubing is for basic insulation and bundling. Dual-wall tubing includes an inner adhesive layer that melts during shrinking to create a moisture-proof, environmental seal.
Heat Shrink Wrap Component Intelligence
Select heat shrink based on shrink ratio, material temperature rating, and adhesive lining requirements.
What are Heat Shrink Wrap components?
Heat shrink wrap provides essential insulation and mechanical protection for cable terminations. Selection hinges on the shrink ratio, operating temperature range, and whether an adhesive lining is required for moisture-proof environmental sealing.
How to Choose Heat Shrink Wrap Components
Match the tubing properties to your environmental and mechanical constraints.
Shrink Ratio
Choose 2:1 for standard applications or 3:1/4:1 for components with significant diameter variations.
Adhesive Lining
Use dual-wall (adhesive-lined) tubing for environmental sealing; single-wall is sufficient for basic insulation.
Material Rating
Select polyolefin for general use, or fluoropolymers for chemical resistance and high-temperature stability.
Operating Temperature
Ensure the continuous operating temperature of the material exceeds your application's thermal environment.
Diameter Sizing
Ensure the recovered diameter is smaller than the cable bundle to ensure a tight, secure fit.
