This heat shrinkable sheath has a diameter of Ø12mm and a shrink ratio of 2:1.  Its intermediate size thickness is designed to ensure excellent resistance to mechanical stress while maintaining a high degree of flexibility. 

The sheath adapts to irregular shapes and provides very good insulation and sealing. It is halogen-free and has a flame-retardant design. It is also RoHS certified.

The ratio of 2:1 means that the diameter of the sheath once heated will be divided by 2. The initial diameter of this sheath is 12mm, once heated and shrunk its diameter will be 6mm.
