KEHS - 225

KEHS-225 is a very flexible, flame-retardant, radiation cross - linked heat shrinkable Polyolefin Tube.
It is designed for a wide range of applications including insulation of electric and electronic parts.
such as wire strain relief, wire terminal resistors and binding of Wires.

DESIGN
- shrink ratio : 50% or more in the radial direction 7% or less in the axial direction
- operation temperature : -55¡É to 125¡É
- high resistance to chemicals and oils.
- standard : UL 224 (File No. E221576)
