Battery Pack PVC Heat Shrink：

• PVC material is heat shrinkable, the thickness is 0.15MM. The length is 1 meter.

• Heating temperature: 85-105 (℃).

• Flat Width: 150mm Length : 1m.Shrinking Rate: Transverse shrinkage ≥50%, longitudinal shrinkage ≤8%;
  

• PVC heat shrinkable tubing is a thin-walled, low-cost material with good electrical and mechanical properties. When exposed to high temperatures in excess of 98 degrees for a few seconds, the specially formulated PVC material shrinks quickly and evenly to conform to the shape of the object being covered.

• Applications include insulation and sheathing of batteries, capacitors and similar objects - a wide range of applications in the production of industrial equipment, toys, sporting goods, electronics and consumer goods.

Instructions for use:

Use a hot air gun for shrinkage treatment; the temperature and time of the hot air gun are critical: if the temperature is low, the shrinkage will not be in place, and there will be creases. If it is high, it will melt.
