Heat Shrinkable Semi-conductive/insulation Tube
Request a Quote
Our composite heat shrink tubing is extruded, irradiated, and expanded to form a dual-wall structure of conductive and insulation materials. The red insulation layer guarantees insulation strength, while the black semi-conductive layer restores electronic shielding. It is suitable for electronic systems up to 42kV.
