Recycled thermoplastic material

When thermoplastic is recycled by a general recycling process alone, only a low-quality recycled plastic material having physical property values lower than a virgin material can be obtained. A recycled plastic material of this invention is made from laser-engraved thermoplastic, metal-containing th...

Beschreibung
Zusammenfassung:	When thermoplastic is recycled by a general recycling process alone, only a low-quality recycled plastic material having physical property values lower than a virgin material can be obtained. A recycled plastic material of this invention is made from laser-engraved thermoplastic, metal-containing thermoplastic, thermoplastic used in an inkjet apparatus, or thermoplastic to which an ink or its composition have stuck. This recycled plastic material is manufactured by pulverizing any of these thermoplastics, cleaning the pulverized thermoplastic, removing a cleaning solution from the cleaned thermoplastic to dry it, and removing from the dried thermoplastic solid matter other than the thermoplastic.
