Mô tả sản phẩm
18650 PVC Heat Shrink Tube - Blue Flame-Retardant Insulation Sleeve for Battery Packs
Product Overview

Our blue PVC heat shrink tube is a specialized insulation and protection solution engineered exclusively for 18650 lithium battery packs. Crafted from high-quality flame-retardant PVC material, it delivers reliable insulation performance, fire resistance, and mechanical protection, effectively safeguarding battery packs from short circuits, moisture, dust, and external impact. With optimized shrinkage properties and a wide operating temperature range, this heat shrink tube is ideal for battery pack assembly in portable power stations, electric tools, energy storage devices, and consumer electronics. Its vibrant blue color also enables easy identification and aesthetic enhancement of battery packs.

Designed for user-friendliness, it can be shrunk with common tools like a hair dryer, making it suitable for both small-batch production and DIY projects. We offer a wide range of specifications to match diverse battery pack sizes, with professional size recommendation services to ensure perfect fitting.

Technical Specifications
Item Details
Material Flame-Retardant PVC
Color Blue
Flat Width Range 30mm - 600mm (Flat width = folded diameter, customizable)
Wall Thickness 0.08mm - 0.2mm
Shrink Temperature 80°C (starts to shrink at 80°C)
Operating Temperature Range -40°C ~ 105°C
Temperature Resistance Grade 120°C (short-term maximum resistance)
Transverse Shrinkage Rate 40% - 50%
Longitudinal Shrinkage Rate 8% - 15%
Core Advantages
  • Flame-Retardant & Insulating: High-quality flame-retardant PVC material prevents fire spread, while excellent insulation performance blocks electrical conduction, avoiding short circuits and enhancing battery pack safety.
  • Optimal Shrinkage Performance: 40%-50% transverse shrinkage rate ensures tight wrapping around battery packs, and 8%-15% longitudinal shrinkage minimizes length loss. Shrinks fully at 80°C for a smooth, wrinkle-free finish.
  • Wide Temperature Adaptability: Operates stably from -40°C to 105°C, with 120°C temperature resistance grade, adapting to harsh working environments and battery operation heat.
  • Easy Application: Can be shrunk with a household hair dryer, hair dryer, or heat shrink machine, suitable for both small-batch and large-scale production. Simple operation reduces assembly time and costs.
  • Customizable Specifications: Flat width ranges from 30mm to 600mm, wall thickness 0.08-0.2mm, supporting personalized customization for diverse 18650 battery pack sizes.
How to Use & Shrink Guide
  1. Open the heat shrink tube and slide it over the battery pack, leaving 3mm of tube extending from both ends of the pack.
  2. Use a household hair dryer on the hot air setting to heat the tube evenly. For larger-diameter or longer tubes, use a heat gun or heat shrink machine for full, uniform shrinkage.
  3. For areas with creases, apply hot air for a slightly longer time to smooth them out, ensuring a tight, neat wrap.
How to Choose the Right Size?

18650 PVC Heat Shrink Tube - Blue Flame-Retardant Insulation Sleeve for Battery Packs 0

First, understand that "flat width" refers to the diameter of the tube when folded. Here’s a simple way to measure and select the correct size:

Step 1: Measure Flat Width

Wrap a piece of paper around your battery pack, remove it, and flatten it – the width of the flattened paper is the required flat width of the heat shrink tube.

Step 2: Reserve Extra Width

It’s recommended to choose a tube with a flat width 5mm-10mm larger than your measured size. A slightly larger tube is easier to slide over the battery pack; a tube that’s too small will be unusable.

Example Calculation

For a battery pack with a width of 280mm and height (thickness) of 120mm: Measured flat width = 280mm + 120mm = 400mm Recommended size = 420mm (reserving 20mm for easy application) Simply provide us with your battery pack’s width and height, and we will recommend the most suitable size for you.

Application Scenarios

This blue PVC heat shrink tube is widely used for 18650 lithium battery pack insulation and protection in:

  • Portable power stations, electric tools, and energy storage devices
  • Consumer electronics (e.g., Bluetooth speakers, power banks)
  • Industrial backup power systems and automotive electronics
  • DIY battery projects and small-batch battery pack production
Customization & Supply Services

We offer flexible customization services based on your battery pack dimensions, including flat width, wall thickness, and even color (on bulk orders). With stable inventory and efficient production capacity, we ensure on-time delivery for both small-batch samples and large-volume orders. Our professional team provides one-on-one size recommendation services to help you select the perfect heat shrink tube.
