- How are plasticizers extracted from PVC?
- Plasticizers may account for 30–35% of the PVC formulation. Extraction and determination of plasticizers in PVC material are critical steps in evaluating a polymer for an intended use. Traditionally, plasticizers are extracted from PVC using a 6-h Soxhlet method and identified using infrared spectrometry or gas chromatography.
- How are PVC samples extracted?
- PVC samples were extracted using a 6-h Soxhlet extraction method (ASTM D 2124) and the accelerated solvent extraction method described above. Both methods used petroleum ether as the extraction solvent. Each extract was thoroughly dried, reconstituted using methy-lene chloride, and analyzed using the GC method described above.
- What is a plasticizer in PVC?
- Plasticizers soften the polymer, aid in the manufacturing process, and provide form and function to various PVC materials. Plasticizers may account for 30–35% of the PVC formulation. Extraction and determination of plasticizers in PVC material are critical steps in evaluating a polymer for an intended use.
- What is accelerated solvent extraction?
- Accelerated solvent extraction is recognized as an oficial extraction method in U.S. EPA Method 3545. This Application Note outlines the basic principles of using accelerated solvent extraction to extract plasticizers such as dioctyl adipate (DOA), trioctyl phosphate (TOP), dioctyl phthalate (DOP), and trioctyl trimellitate (TOTM) from PVC.
