The 3M Heat Shrink Tubing HDT-AN is a thick-walled, halogen-free heat shrink tubing made from modified, cross-linked polyolefin. It is suitable for use on all plastic and mass cables for installations both indoors and outdoors, as well as for underground applications. It serves to insulate and seal connections of all kinds, particularly as an outer tubing for control cable assemblies. For improved sealing, it features an adhesive coating on the inner wall. This highly aging-resistant heat shrink tubing is UV-resistant and resistant to many chemical influences. Its shrink ratio is four to one, and it can be used in a temperature range of -55 °C to +130 °C. It is not self-extinguishing.
