Beschreibung
Zusammenfassung:	A polymer thick film carbon black composition comprising 6-13 wt % conductive carbon black powder; and 87-94 wt % organic medium comprising thermoplastic polyurethane resin dissolved in an organic solvent may be used to form the resistive element of heaters in applications where significant stretching is required, particularly on substrates that can be highly elongated and, in particular, that can be used in wearable garment applications.
