Adhesive Insulation Highland Barley Paper

Product Description
Battery Raw Material Custom Color Highland Barley Paper (18650/21700/26650/32650) – Adhesive, High-Temperature Resistant
In lithium battery pack assembly (especially for cylindrical cells like 18650, 21700, 26650, and 32650), reliable insulation and heat resistance between cells are critical to prevent short circuits and ensure safety. Our Highland Barley Paper with Adhesive solves the limitations of ordinary insulating papers: made from natural highland barley fiber, it combines strong high-temperature resistance, excellent dielectric strength, and easy application via pre-applied adhesive—making it ideal for spacing and insulating cylindrical battery cells in EVs, power tools, energy storage systems, and consumer electronics.
Core Advantages: Why Choose Highland Barley Paper with Adhesive?
Advantage Key Benefit for Battery Pack Manufacturers
Multi-Cell Compatibility Pre-cut sizes (or roll form) for 18650/21700/26650/32650 cylindrical cells—no extra trimming needed, saving assembly time.
Extreme High-Temp Resistance Withstands continuous use at 180℃ (short-term up to 220℃), outperforming standard paper insulators (typically ≤120℃).
Strong Adhesive Backing High-tack acrylic adhesive ensures secure bonding to battery cells; resists peeling even under vibration or temperature cycles.
Natural & Eco-Friendly Made from renewable highland barley fiber—non-toxic, halogen-free, and compliant with environmental standards (RoHS/REACH).
Thin Yet Durable 0.08mm–0.2mm thickness saves space in compact battery packs; tensile strength ≥30MPa to resist tearing during assembly.
