Applications

Our PVDF heat shrink tubing offers superior heat resistance, abrasion resistance, mechanical durability, and resistance to chemical media. It is designed to thrive in environments with corrosive air, thermal cycling, or mechanical stress.
It offers superior flame retardancy, widely used for wiring in automobiles, aviation, marine vessels, and electronic devices.
Its transparency makes it suitable for encapsulating electronic components and providing clear identification.
