Extraction of plasticizers: An entire and reproducible
The extract can also be used to analyse the presence of plasticizers with Thin Layer Chromatography (TLC) [21]. It could also be shown that the extraction method is not only applicable to CA sheets but also to photographic films and animation cells. It will be shown if the extraction method is also applicable to other polymers. Data availability

solvent extraction or Soxhlet conditions described above. AN70640_E 07/13S Application Note 336 Method Validation When developing extraction methods, one way to validate extraction efficiency is to re-extract the same sample and check for remaining analytes. The Dionex ASE system allows the analyst to automate re-extraction for easy method

ELVALOY Copolymer Alloys | Plastics Modification | Dow Inc.
ELVALOY is a flexible polymer that is highly miscible with PVC during the PVC compounding stage. This makes it a useful PVC plasticizer. Because it is a high-molecular-weight, solids-phase (non-liquid) PVC plasticizer, ELVALOY adds permanent flexibility to the PVC compound, enabling higher-value use in more demanding applications.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates. They are made from aliphatic dibasic acids such as adipic acid and alcohols.
- 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.
- 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.
- 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 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.
