Green PVC Heat Shrink Tubing – Battery & Wire Insulation Sleeve (7mm–200mm)

Measure the outer diameter of the object you want to cover, then multiply by approximately 1.57 to get the required flat width. For example, a 10mm diameter wire bundle typically needs a flat width of about 16mm. When in doubt, size up slightly — PVC heat shrink tubing generally shrinks to about half its flat width when heated, so a slightly larger sleeve will still conform tightly. For battery cells, check the cell's datasheet for the exact diameter.

This green PVC heat shrink tubing typically has a 2:1 shrink ratio, meaning it shrinks to approximately half its original flat width when heat is applied. For example, a 20mm flat-width sleeve will recover to roughly a 10mm inner diameter. The exact recovered diameter may vary slightly by size — contact us to confirm for your specific variant if tight tolerances are required.

PVC heat shrink tubing generally provides good moisture resistance for indoor and light-duty outdoor use. It is not rated for prolonged UV exposure or continuous submersion. For harsh outdoor, marine, or underground applications, we recommend polyolefin or adhesive-lined (dual-wall) heat shrink tubing instead. For protected outdoor enclosures or short-term weather exposure, this tubing is generally suitable.

This PVC heat shrink tubing typically activates at around 90–120°C (194–248°F). A heat gun set to low or medium is the recommended tool — move it steadily along the tubing to shrink evenly from one end to the other. Avoid using open flames such as lighters or torches, as they can scorch, discolor, or unevenly shrink the tubing and may damage the underlying wire insulation.

Yes — green PVC heat shrink tubing is widely used to wrap and insulate lithium-ion battery cells (18650, 21700, and similar formats) and assembled battery packs. It provides electrical insulation between cells and helps identify battery groupings or polarity by color. Before ordering, confirm the flat width matches your cell's outer diameter using the 1.57× formula above. For large prismatic or pouch cells, choose from the wider flat-width options (50mm and above).

For wrapping individual battery cells or short wire segments, a 1-meter roll is generally sufficient for small projects (typically 10–20 cells depending on cell height). For wiring harnesses, cable management runs, or bulk production work, 5–20 meter rolls offer better value per meter. We recommend adding 10–15% extra to your calculated length to account for trimming, test cuts, and any misaligned shrinks.

PVC heat shrink tubing in this size range is typically rated for low-voltage applications up to 600V. It is suitable for most consumer electronics, battery packs, automotive wiring, and control panel cable management. For high-voltage, industrial, or UL-listed applications, please contact us to confirm the specific rating for your chosen size before ordering.
