Fluoroplastic-Processed Highland Barley Insulation Sheet 99mm 100m Roll for 18650 21700 Battery Cell Wrapping

Product Overview

This 0.2mm fluoroplastic-processed highland barley insulation sheet is precision-engineered for cylindrical battery cell wrapping in 18650 and 21700 lithium-ion battery production lines. The fluoroplastic treatment enhances surface durability and tear resistance, while the 99mm width is optimized for high-speed automated wrapping machines. With 4000V voltage withstand and 130℃ continuous temperature resistance, it ensures reliable electrical isolation throughout the battery lifecycle.
