It wasn't the recycling, but certain softening compounds in PVC were suspected to cause cancer and reduced by law. This war aimed at children's toys and other playstuff, but hit wire insulation as well (though nobody would use wire insulation for a lolly). Furthermore, machine oil and above all cooling compounds would dissolve and remove the new softeners more readily than the old ones, leaving hard PVC. Same problem is with rubber insulation, too. There are oilproof cables, though, Oelflex brand (made by Lapp Cables) for instance. Peter
