Phthalate ester plasticizers were determined in rivers and dams of the Venda region, South Africa. Liquid-liquid extraction, column chromatographic clean-up and capillary gas chromatography
In the process of production, processing, transportation, and storage of edible oils, the oils inevitably come into contact with plastic products. As a result, plasticizers migrate into edible oils, are harmful to human health,
- How are phthalate ester plasticizers determined?
- ABSTRACT Phthalate ester plasticizers were determined in rivers and dams of the Venda region, South Africa. Liquid-liquid extraction, column chromatographic clean-up and capillary gas chromatography were the methods used for the quantitative analyses.
- How to choose an ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will help in selecting an ester plasticizer. ASTM D883, "Plastics Nomenclature," American Society for Testing and Materials, Philadelphia, PA.
- Do fluorocarbon elastomers accept ester plasticizers?
- Fluorocarbon elastomers will accept a relatively wide range of ester plasticizers, but here, with both the high temperature post cure and application temperatures ranging to 232°C, they find use only at very low levels for processing. The selection of an ester plasticizer can often be confusing because of the large choice available.
- Which plasticizers are used in combination with specialty monomeric esters?
- Flame-retardant plasticizers, phosphate esters and chlorinated paraffins are often combined in usage with flame-retardant plasticizers frequently used in combination with specialty monomeric esters. Both materials are inefficient plasticizers, thus explaining their combinations with specialty monomerics.
- Why are ester plasticizers important for elastomers?
- Ester plasticizers make it possible to process elastomers easily while also providing flexibility in the end-use product. Plasticizer–elastomer interactions are governed by many factors, such as solubility parameter, molecular weight and chemical structure.
- Which type of plasticizer enters the polymer system first?
- Primary plasticizers enter the polymer systems first. Plasticizers entering the crystalline regions of crystalline or semi- crystalline polymers are referred to as primary. If the amorphous regions of those polymers are penetrated, the plasticizer may be considered a solvent type.
