## Description

PVC heat-insulating tube for wrapping and insulating battery packs, ideal for 5S configurations with 18650 cells. Folded width 190 mm, circumference 380 mm, shrinks uniformly at 100 degrees C with a shrinkage rate of 48% horizontally and 12% vertically. Blue color, high resistivity for electrical protection in technical applications.
Heat-shrinkable PVC tube, 190mm, insulating, used for wrapping battery packs.
The size refers to the width of the folded tube (its circumference being double). To correctly calculate the size of the tube, measure the perimeter of the battery and choose a tube with a size larger than its circumference.
