Abstract:
A process for producing a composite product having a predetermined shape, said process being characterized by subjecting a mixture of particles of thermoplastic material and particles of waste or filler material to a mixing operation of such high intensity so as to raise the temperature of the particles of thermoplastic material and particles of waste or filler through particle collision until the particles of thermoplastic material reach a molten state causing the molten plastic to coat and bond with the hot particles of waste or filler material to form a hot mass of particles of waste or filler material which are both coated with and bound together by said thermoplastic material and then with the thermoplastic material in the molten state, compressing the hot mass to force the thermoplastic material into any interstices and irregularities of the particles of waste or filler material while forming the hot mass to a desired product shape to produce, upon cooling thereof, a compacted composite product in which the particles of waste or filler material are encapsulated by the thermoplastic material.
