Dustproof 18650 PVC Heat Shrink Film 72mm×30mm – Battery Insulation & Short-Circuit Prevention
When assembling 18650 lithium batteries, reliable insulation is the first line of defense against short circuits, moisture damage, and safety hazards. Our 18650 PVC Heat Shrink Film (72mm x 30mm) is tailored to solve the pain points of ill-fitting or low-quality shrink wraps: it offers precise dimension matching, fast and uniform shrinking, and long-lasting insulation protection—making it ideal for both individual battery cell insulation and small battery pack wrapping. Crafted from high-grade PVC material, it balances flexibility, heat resistance, and cost-effectiveness, ensuring your 18650 batteries stay safe and functional in every application.
| Advantage | Key Benefit for Battery Assemblers |
|---|---|
| 72mm×30mm Precise Fit | Optimized dimensions for standard 18650 cylindrical cells (18mm diameter × 65mm length)—after shrinking, it tightly wraps the battery without excess material or loose edges, ensuring neat insulation. |
| Fast & Uniform Shrinkage | Shrinks quickly at 80℃–120℃ (compatible with heat guns or shrink tunnels); uniform shrinking rate (30%–35%) avoids wrinkles or bubbles, reducing rework and improving assembly efficiency. |
| Reliable Insulation & Protection | Excellent electrical insulation (volume resistivity ≥10¹⁴Ω·cm) prevents short circuits between cells; also blocks dust, moisture, and minor scratches, extending battery lifespan. |
| Flexible & Tear-Resistant | High-grade PVC material with good flexibility—won’t crack during shrinking or bending; tear resistance ≥20N/cm ensures durability during battery handling and installation. |
| Cost-Effective Bulk Supply | Available in large rolls (100m/roll, 500m/roll) with competitive pricing—ideal for mass production of 18650 battery packs (e.g., power banks, flashlights) without compromising quality. |
