This PVC heat shrink tubing is engineered for secure insulation and professional-grade packaging of 18650 lithium battery cells and other electronic components. Designed for consistent shrink performance and high electrical resistance, this product ensures stable protection in both industrial and DIY applications.

Key Features

• Reliable heat shrinkage at 100°C with horizontal shrinkage of 48 ± 3% and vertical shrinkage of 12 ± 3%
• Usable with heat shrink machines, hot air blowers, and water-based shrink methods
• High flexibility; resists cracking after multiple 1-meter drop tests on cement surfaces
• Color stability maintained when stored at 30°C with no discoloration
• Low water absorption (≤0.5%) and minimal natural shrinkage (≤0.5% at 30°C)
• High resistivity of ≥1 × 10¹⁵ Ω/cm³ at room temperature (≤65% relative humidity)
• Strong electrical insulation properties with high breakdown voltage across multiple thickness ranges
• Suitable for applications including battery packs, electrolysis fuses, lighting components, inductors, metal pipes, and wire/cable joints
