Polyolefine (PO) heat-shrink conduit, type ST-BT-HHalogen-free Polyolefine heat-shrink conduit for labelling cables with excellent properties for use with the thermal transfer method. This conduit, with its special approvals, is particularly suitable for applications in the fields of air and rail transport, marine, offshore and tunnel construction.The pre-perforated ST-BT-H 20/12 heat-shrink conduit is divided into a 20 mm long section for cable identification and a 12 mm long section, which contains information to simplify wiring the circuits. This section can be discarded after the circuit is wired. This method helps to significantly reduce the processing timePropertiesExcellent printing propertiesFlat-rolled for thermal transfer method printingHalogen-free, thin-walledShrink ratio of 2:1 (the recommended shrink range is -20 % of the max. value and +20 % of the min. value)Vehicle category 1a according to BS 6853 (1999)Fire resistance ASTM D 635-HBShrink temperature >90°CApplication temperature -55°C to +105°C
