Politubes offers a wide range of heat shrinkable polyester spiral wound tubes for the insulation and protection of automotive, energy and military batteries.

In addition to protection and insulation, another fundamental purpose of our heat-shrinkable tubes is to reduce overheating, the thermal runaway of the cells, improving their safety and performance.

For this application we produce our tubes by using different types of heat shrinkable polyester type like Mylar HS or low shrinkable polyester type 2LSO.
