| High Light | 180℃ High-Temp Resistance Highland Barley Paper ，0.08mm–0.3mm Thickness Battery Insulation Paper ，Adhesive Backing Insulation Highland Barley Paper | ||
When assembling cylindrical lithium battery packs (18650, 21700, 26650, 32650), reliable insulation, heat resistance, and easy assembly are non-negotiable—yet ordinary insulating papers often fall short on one or more fronts. Our Custom Color Highland Barley Paper solves this by blending three key strengths: extreme high-temperature resistance, strong pre-applied adhesive, and customizable colors for visual differentiation. Made from natural highland barley fiber, it’s not just an insulator—it’s a production-friendly solution that streamlines assembly, enhances safety, and lets you match your brand or module identification needs.
| Advantage | Key Benefit for Battery Pack Manufacturers |
|---|---|
| Customizable Colors | Available in red, blue, green, black, white, or your brand color—enables quick visual sorting (e.g., 区分 different battery modules or production batches) and reduces assembly errors. |
| 180℃ High-Temp Resistance | Withstands continuous use at 180℃ (short-term up to 220℃), outperforming standard PET or kraft paper (≤120℃) and avoiding insulation breakdown during battery charging/discharging. |
| Strong Adhesive Backing | High-tack acrylic adhesive bonds firmly to battery casings; resists peeling even under vibration (ideal for e-scooters/EVs) or temperature cycles (-40℃ to 180℃). |
| Natural & Eco-Friendly | Made from renewable highland barley fiber—halogen-free, non-toxic, and RoHS/REACH compliant, fitting green energy and consumer electronics standards. |
| Thin & Space-Saving | 0.08mm–0.2mm thickness saves critical space in compact battery packs (e.g., power banks, laptop batteries) without compromising insulation performance. |
