Number, concentration, and number of nonpolymer-identical organic and inorganic foreign substances are increasing. With each new thermal stress, the natural overseas substances will react by decomposition. This is causing the liberation of additional degradation-supporting substances and coloring substances. The mechanical recycling the place the original polymer properties are being maintained or reconstituted.
