In recent times it has been common to call recycled PET and recycled HDPE compounds (usually produced from recycled bottles) as rPET and rHDPE respectively.

The term "rGrade plastics" is an extension to this and essentially refers to any plastic raw materials that have been or can be recycled.

These are materials that may have derived from production waste of the various moulding processes of plastic products but more usually will be waste plastics derived from plastic products at the end of their first useful life.

rGrade plastics will typically have been processed in some way, either to densify them (such as the compounding of EPS fish boxes or baling of packaging film) or size reduced (shredded, granulated, crumbled etc.) ready for further processing either directly into finished products or into recycled plastic compounds.

rGrade can also be used to refer to these recycled plastic compounds which have colourants and product enhancing additives compounded in with the base raw material to produce a higher quality and more consistent product for moulding than non-compounded raw materials.

CK Polymers Plastic Distribution offer recycled / recyclable (rGrade) plastic raw materials in a wide range.
