Politubes produces a wide range of tubes & sleeve for batteries (cells & battery packs) used in automotive, energy, military and aerospace application.

Our tubes are produced through the spiral wound technique without closure overlaps and this guarantee some key benefits as:

• optimizing spaces and filling factor;
• improving safety inside battery packs;
• reduced risk of heat peaks that may occur in the film overlapping area of closure.

We use only the most reliable raw materials selected over the years from the world’s leading manufacturers.
The reasons they are used are:

• Electrical insulation and short-circuit prevention;
• Thermal management and overheating limitation;
• Prevention of thermal runaway in lithium-ion cells by increasing their safety and correct performance;
• Flame resistance and delay of fire spread.

Politubes custom designed tubes are a reliable solution engineered by using shrinkable polyester (Mylar and 2LSO), Nomex, Kapton (polyimide), DyBond in accordance with specific customer requirements.
