| Form形态 | Flat film / lay-flat sleeve optional 平膜 / 对折套管二选一 |
| Thickness厚度 | 0.10–0.20 mm (high-end grade avoids ultra-thin to ensure insulation) 0.10–0.20mm（高端不做超薄，保障绝缘强度） |
| Width宽度 | 20–1500 mm 20–1500mm |
| Shrink temperature收缩温度 | 85–105 °C 85–105℃ |
| Shrinkage收缩率 | TD 42–48%, MD ≤10% (strict MD to stop module shifting) 横向 42–48%，纵向 ≤10%（防模组移位拉扯） |
| Electrical电气指标 | Rated 300 V, breakdown ≥8 kV; anti-static surface 10⁸–10¹¹ Ω 额定 300V，击穿 ≥8KV；抗静电表面电阻 10⁸–10¹¹Ω |
| Working temperature使用耐温 | -20 °C ~ 105 °C; anti-UV formula for outdoor use -20℃~105℃；户外可选抗 UV 配方 |
| Flame retardant阻燃 | Standard flame-retardant & upgraded VW-1 versions 基础阻燃、升级 VW-1 两个版本 |
| Surface表面 | Matte preferred for ESS clients (anti-reflection, anti-static) 储能客户偏好哑光（不反光、防静电） |
Product advantages产品优点
- High safety margin: outperforms economical PVC film for high-safety scenarios安全冗余高：绝缘指标优于普通经济型 PVC，适配高安全要求场景
- Anti-static version solves assembly static risk — a must for ESS PACK抗静电款解决电芯组装静电风险，是储能 PACK 刚需
- Anti-aging: resists embrittlement under long sun exposure in PV storage耐老化：光伏储能户外长期日晒不易脆化开裂（普通 PVC 户外老化快）
- Minimal post-shrink deformation: no pulling or shifting on large modules收缩形变极小：大尺寸模组包覆后无移位拉扯
- Stable batches with per-batch COA, convenient for UL & CE pack certification批次稳定：每批附 COA，方便电池做 UL、CE 整套认证
- One-stop supply: standard film, sleeve and insulation film from one factory with unified QC一站式配套：普通膜、套管、绝缘膜同厂供应，统一品控
Application scenarios适用场景
- PV, residential and commercial & industrial ESS battery packs光伏储能、户用储能、工商业储能电池包
- High-power electric equipment, forklift batteries, AGV power modules大功率电动设备、叉车电池、AGV 动力电池模组
- High-safety lithium PACK and internal insulation of ESS cabinets高安全要求锂电池 PACK、储能柜内部绝缘包覆
