AN336: Accelerated Solvent Extraction of Plasticizers from

Polyvinyl chloride (PVC) polymers are typically composed of resins, stabilizers, pigments, and plasticizers. Plasticizers, 30–35% of the formulation, are used to soften the polymer, increase manufacturability, and provide form and function. Extraction and determination of plasticizers in PVC material are critical steps in evaluating a polymer for an intended use. This Application Note

Accelerated Solvent Extraction for Additives in Polymer Materials

The accelerated solvent extraction technique improves the extraction efficiency of plasticizers from polymers by using elevated temperature and pressure. Many of the organic solvents used in these extractions boil at relatively low temperatures at atmospheric pressure (e.g., acetone boils at 56 °C). By exerting a pressure of 1500 psi (10 MPa

In the fourth extraction no plasticizers could be detected anymore. Methanol is therefore an efficient solvent for plasticizers extraction. The extraction with methanol was validated by repeating the procedure several times with different CA materials. Three extractions with methanol led in each case to a total extraction of plasticizers.

Effect of Protective Coating on Extraction of Plasticizer

Abstract The mechanism of desorption of a plasticizer from polyvinyl chloride and its effect on the extraction rate, which decreases after desorption of a certain proportion of the plasticizer, have been studied. Parameters of the transfer of plasticizer from polyvinyl chloride to the environment reflecting the rate and conditions for decreasing the rate of desorption have been proposed. A
