ABSTRACT:
An integrated multiple particle heating agent is provided for heating, particularly using the agent for heating and bonding plastic substrates. The integrated multiple particle heating agent includes significant portions of non-conductive ferromagnetic oxide particles which generate heat because of hysteresis losses and of conductive ferrous particles which generate heat because of eddy current losses. The dual particles are thoroughly intermixed and respond to a magentic field of an appropriate RF frequency. The ferromagnetic particles are submicron size and the ferrous particles are micron size. The particles are combined with an inert resin carrier and applied as a coating, directly incorporated within the substrate, or as a separate element. The ferromagnetic oxide loading is generally less than the ferrous particle loading, with a range of 30 to 60 percent (40 to 50 preferred) by weight of ferrous particles and a range of 10 to 50 percent (15-25 preferred) by weight of the oxide particles. The radio freqency magnetic field can be in the range of 1.2 to 7 megahertz (MH.sub.z) with 3.5 to 4 MH.sub.z being typical. The integrated submicron sized ferromagnetic particles and micron sized ferrous particles generate heat at a significantly and unexpectedly high rate using a single RF magnetic field of a relatively low frequency. The percentage loading may vary with different substrates.
