The PET heat shrink tube for batteries is mainly used in 14500,18650,21700,26700 and other small cylindrical lithium batteries as well as all kinds of battery packs. In recent years, with the rise of new energy power and energy storage industry, Changyuan Changtong has cooperated with domestic and foreign head battery enterprises to develop the corresponding heat shrink tube, and has realized the industrialization production of PET tube for 32650,40132，46800，60138and other large cylindrical batteries. The PET heat shrink tube for the battery has the advantage of low-temperature shrinkage and flatness. It has the characteristics of high and low-temperature cycle test tubes without deformation, good coating after charge and discharge, wear resistance and impact resistance, etc. The product meets the environmental protection requirements of the European Union does not contain halogen, meets the environmental protection standards.
Insulation: Protecting battery cells from external elements and preventing short circuits.
Physical Protection: Shielding batteries from mechanical damage during handling and operation.
Sealing: Providing a moisture barrier to enhance the longevity and reliability of battery systems.
