High Light Cross-Linked PE Heat Shrink Sleeve21700 26650 Battery Insulation Tube120℃ Blue Shrink Tube 2:1 Ratio
Blue Cross-Linked PE Heat Shrink Tube for 21700 26650 Battery Cell Insulation

Product Overview

This blue cross-linked polyethylene (PE) heat shrink tube is engineered for 21700 and 26650 large-format cylindrical battery cell sleeve insulation. Cross-linked PE delivers superior chemical resistance, mechanical strength, and thermal stability compared to standard PVC tubing. The 50mm flat width accommodates larger cell diameters while the 2:1 shrink ratio ensures tight, wrinkle-free conformity after 80℃ heat activation. Blue color provides professional appearance and easy visual identification in multi-format battery production environments.

Key Features
  • Cross-Linked PE Material: Superior chemical resistance and mechanical strength compared to PVC, with 120℃ short-term temperature resistance for demanding battery manufacturing environments
  • 2:1 Shrink Ratio: Consistent 50% transverse shrinkage ensures tight, uniform coverage over 21700 and 26650 cell casings without wrinkles or air pockets after 80℃ activation
  • 50mm Flat Width: Optimized for 21700 (21mm diameter) and 26650 (26mm diameter) cells, providing full circumferential coverage with minimal material overlap
  • 100m Continuous Roll: Extended roll length reduces changeover frequency on automated sleeving lines, improving production throughput
  • 40%-50% Transverse Shrinkage: Reliable, consistent shrinkage within specification ensures predictable post-shrink dimensions for quality-controlled cell assembly
Applications
  • 21700 cylindrical cell PVC-free sleeve insulation for EV battery packs
  • 26650 large-format cell casing insulation for energy storage systems
  • High-temperature battery assembly lines requiring 120℃ rated sleeving material
  • Compatible with automated heat shrink tube applicators and hot-air shrinking tunnels operating at 80℃
