The amount of heat generated by friction in the material is dependent on field strength, frequency, dipole strength, and free volume in the material. [1] Since the main driving force for dielectric heating is the interaction of the dipole of a molecule with the applied electrical field, RF welding can only be conducted on dipole molecules.
