How much recycled material can you put into expanded polystyrene before it is no longer considered virgin?
Is there a certian percentage or must it be absolutely zero percent recycled material to be called "virgin" material.
I am specifically asking about expanded polystryene (EPS or styrofoam) but if something applies to all plastics that would be great
US EPS suppliers commonly use the "virgin" designation for only 0% recycled material content domestically. The more recycled content, the more brittle (and abrasive to your product) it will be. Since the recycle % can affect performance even if it is only 10%, it's best to specify unless you can deal with the weaker material.
