Extraction of Additives from Plastics

Abstract

The EDGE® automated extraction system is the most advanced extraction system available for the extraction of additives from polymers. The EDGE combines pressurized fluid extraction and dispersive solid phase extraction to dramatically reduce the sample preparation time and the potential of human error. The extraction is simple, repeatable, and fast, lasting less than 20 minutes, which includes sample cooling and system washing.

The extraction of polypropylene and polyethylene was performed with the EDGE and ASTM methods D6043-09 and D6953-11. Recovery results are published and discussed.
