Standard Practice for Extraction of Additives in Polyolefin Plastics

Importancia y uso:

5.1 Separation and identification of additives used in the manufacture of polyolefin plastics is necessary in order to correlate performance properties with polymer composition. This practice provides guidelines for extracting phenolic antioxidants, phosphite antioxidants, UV stabilizers, antistatic agents, and slip additives, from milled polyolefin plastics .

5.2 Water bath shakers and steam-reflux Soxhlet extraction techniques have also been used to successfully remove additives from polyolefin plastics.
