Abstract
Granite-like plastics useful in all forms of molding and thermoforming are disclosed. The granite-like plastics include a multiplicity of particulates formed of a thermoplastic and thermoset plastic combination which are suspended within a clear or translucent matrix of the same thermoplastic material as the particulates. The particulates are maintained in suspension due to their isopynic density with the matrix. Of particular importance are granite-like acrylics that can be used in place of standard acrylics.
Claims13
A simulated mineral article which comprises a plastic material suspended within a thermoplastic matrix, the plastic material and the thermoplastic matrix being visually differentiatable, substantially immiscible and substantially isopycnic in density, the plastic material comprising both a thermoplastic and a thermoset plastic, the thermoplastic matrix consisting essentially of a thermoplastic.
A method of preparing a simulated mineral article, which comprises:
- (a) preparing a liquid thermoplastic matrix consisting essentially of a thermoplastic;
- and
- (b) suspending a plastic material within the liquid thermoplastic matrix, the plastic material having been formed by mixing a thermoplastic with a thermoset plastic so that the plastic material has the same specific gravity as the liquid thermoplastic matrix.
