Abstract
An improved process for dispersing filler particles in a resin composition is disclosed. The filler particles, for instance electrically conductive or metal particles, are mixed with a resin material or blend of materials including a resin material to form a mixture that is subjected to an acceleration force. The acceleration force can be generated by passing the mixture through a static nozzle having particular dimensions to generate an acceleration of the mixture in the nozzle in excess of 400,000 m/sec2. The treated particles become uniformly dispersed in the resin composition and a reduction in average particle size of the filler material can be achieved.
