Dielectric parameters microwave method vulcanisation elastomers monitoring The application of microwave measure-ments to the characterisation of rubber compounds vulcanisation is considered. The behaviour of mechanical and micro-wave (20 GHz) dielectric parameters dur-ing vulcanisation was investigated for rubber compounds with different con-centrations of active and non-active car-bon black. An increase of concentration or activity of carbon black results in the increase of both dielectric permittivity e 0(T) and loss e 00(T) and in the increase of torsion modulus as well. The start of the vulcanisation reaction is indicated by an increase of dielectric permittivity and torsion modulus in all investigated un-vulcanised compounds with carbon black. While for compounds with non-active carbon black the vulcanisation can be better indicated by the e 0(T) anomaly, for compounds with active carbon black it is more clearly seen by the change of e 00(T) behaviour.
