Professional High Grade 18650 Battery Insulation Gasket and Industrial Barley Paper Heat Shield

Ensure the ultimate safety and structural integrity of your custom power solutions with high-performance electrical protection. This 18650 battery insulation gasket, commonly known as barley paper or fish tape, is a professional-grade dielectric material engineered for high-density Li-ion battery pack assembly. Featuring an ultra-thin 0.008-inch (0.2mm) profile, it provides critical electrode insulation that prevents short circuits and manages heat dissipation within complex cell arrays. Whether you are rebuilding an e-bike battery, constructing a portable power station, or performing precision electronics repair, this insulating glue fish tape offers the industrial-strength reliability required for high-voltage applications.

Key Features

• Superior Dielectric Protection: Specifically treated green shell paper provides exceptional electrical insulation, preventing hazardous contact between battery terminals and nickel strips.

• Thermal and Shock Resistance: Engineered to withstand high operating temperatures and absorb micro-vibrations, extending the lifespan of your 18650 battery packs.

• Professional Grade Adhesive Backing: Features a high-bond insulating glue that ensures a permanent, bubble-free attachment to the electrode surface, even under thermal expansion.

• Customizable Large Format Roll: Delivered in a 3.3-foot (1 meter) length with a wide 4.7-inch (120mm) surface, allowing for precision cutting to fit any custom battery configuration.

Why Choose Our Professional Barley Paper Insulation

Unlike standard tapes that can degrade or melt under heat, our battery pack insulating patch functions as a vital safety hardware shield. It utilizes high-density fibers that offer excellent mechanical strength, making it resistant to tearing during the assembly process. The 0.2mm thickness is meticulously calibrated to provide maximum insulation without adding unnecessary bulk to your battery enclosures. This is an essential component for engineers, DIY enthusiasts, and technicians who demand professional manufacturer standards for their lithium-ion projects and energy storage systems.

Perfect For

• Custom Li-ion Battery Builders: A mandatory safety component for insulating the positive terminals of 18650 cells during spot welding and pack assembly.
