Product Description
Product Overview
This 72mm × 30mm PVC heat shrink film provides reliable insulation and short-circuit prevention for 18650 lithium batteries. Engineered with precise dimensions and high-grade PVC material, it ensures optimal protection against dust, moisture, and electrical hazards.
Core Advantages
Precise 72mm × 30mm Fit
Optimized for standard 18650 cylindrical cells (18mm diameter × 65mm length) - shrinks tightly without excess material or loose edges
Fast & Uniform Shrinkage
Activates at 80°C-120°C with 30%-35% transverse shrink rate - eliminates wrinkles and bubbles
Reliable Insulation
Volume resistivity ≥10¹⁴Ω*cm and dielectric strength ≥15kV/mm prevent short circuits
Tear-Resistant Construction
Tear resistance ≥20N/cm and tensile strength ≥15MPa ensure durability during handling
Cost-Effective Bulk Supply
Available in 100m and 500m rolls with competitive pricing for mass production
