ABSTRACT:
Disclosed is a cold molding process for the production of a unitary article from a plurality of plastic particles. The process may be conducted without the addition of heat. A plurality of homogeneous or heterogeneous plastic particles are introduced into a mold, softened by exposure to a softening agent, and thereafter compressed to form the unitary article. Preferred softening agents comprise an organic component and an aqueous component. One preferred softening agent-plastic combination comprises aqueous methylethylketone and polystyrene.
