Product Description

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.

Core Advantages

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.

Application Scenarios

Consumer Electronics: Insulating individual 18650 cells for power banks, portable chargers, wireless speakers, and laptop batteries—prevents short circuits from metal contact.
Lighting Devices: Wrapping 18650 cells in flashlights, headlamps, and LED work lights—blocks dust and moisture, ensuring stable performance in outdoor use.
Small Energy Storage: Insulating cells in mini solar power banks, backup batteries for routers, and IoT device batteries—protects against environmental factors.
DIY Battery Projects: Ideal for hobbyists assembling 18650 packs for RC cars, drones (small-scale), and home electronics—easy to use with standard heat guns.
Industrial Auxiliary: Insulating 18650 cells in handheld medical devices, sensors, and portable meters—meets basic insulation safety standards for industrial use.

How to Use

Cut to Size: If using roll form, cut the film into 30mm lengths (or your desired size) using a utility knife or film cutter.
Cover the Battery: Slide the 18650 cell into the 72mm×30mm film, ensuring the entire cell (except the positive/negative terminals if needed) is covered.
Apply Heat: Use a heat gun (set to 100℃-120℃) or shrink tunnel to apply uniform heat to the film. Move the heat source back and forth to avoid overheating—the film will shrink tightly around the battery in 5-10 seconds.
Cool & Inspect: Let the battery cool for 10-15 seconds, then check for wrinkles or loose areas (reapply heat if necessary).

Customization & Order Support

Customization Item	Available Options
Dimensions	Custom width (50mm-100mm) and length (20mm-50mm) for non-standard 18650 cells
Color	Black, red, blue, green (MOQ 500m per custom color)
Thickness	0.03mm-0.08mm (adjustable for different insulation needs)
Packaging	Customized roll lengths (e.g., 200m/roll) or pre-cut pieces in branded packaging

Quality Assurance & After-Sales

Quality Testing: Each batch undergoes shrinkage rate, insulation resistance, and tear strength tests—test reports provided free for bulk orders.
Certifications: Compliant with RoHS and REACH standards—safe for consumer and industrial electronics.
MOQ & Lead Time: Standard clear film: MOQ 10 rolls (100m/roll), ships in 2-3 days; Custom colors/sizes: MOQ 500m, delivers in 5-7 days.
After-Sales: Free sample roll (1m) for testing; 3-month warranty for quality issues (e.g., uneven shrinkage, poor insulation).
