Introduction to 26650 Lithium Battery PET Heat Shrink Tubing
The 26650 lithium battery PET (Polyethylene Terephthalate) heat shrink tube is an essential component in the battery manufacturing and DIY battery pack assembly industries. This specialized tubing is designed to provide insulation, protection, and structural integrity to lithium batteries, particularly the 26650 size, which is widely used in various applications, including electric vehicles, power tools, and portable electronics.
Material and Properties
PET is a thermoplastic polymer known for its excellent electrical insulation properties, chemical resistance, and durability. When heat is applied, PET tubing shrinks to fit snugly around the battery, creating a tight seal that protects against moisture, dust, and mechanical damage. This shrinkage occurs at relatively low temperatures, making it safe for use with sensitive electronic components.
Applications
The primary application of lithium battery PET heat shrink tubing is to encase the battery cells such as 10440 battery cells, 14500 battery cells, 16340 battery cells, 18650 battery cells, 21700 battery cells, 26650 cells, 32650 cells, 40132 cells, 46800 cells, 60138 cells, etc, providing a protective layer that enhances safety and performance. It helps prevent short circuits by insulating the battery terminals and reduces the risk of physical damage during handling and transportation. Additionally, the tubing can be printed with labels or color-coded for easy identification, which is particularly useful in battery packs containing multiple cells.
Installation Process
Installing PET heat shrink tubing is straightforward. First, the sleeve tube is cut to the desired length and slipped over the battery. A heat gun is then used to apply heat evenly around the tubing, causing it to shrink and conform tightly to the battery's shape. This process not only secures the battery but also improves its aesthetic appeal.
Benefits
Using PET heat shrink tubing offers several advantages:
Enhanced Safety: Providing insulation minimizes the risk of electrical shorts.
Durability: The robust nature of PET ensures long-lasting protection against environmental factors.
Versatility: It is suitable for various battery sizes and types, making it a flexible choice for manufacturers and hobbyists.
In conclusion, lithium battery PET heat shrink tubing is a vital accessory for anyone working with lithium batteries. Its combination of protective qualities, ease of use, and versatility makes it an indispensable tool in both industrial and DIY applications.
