Identification of Additives in Polypropylene and Their Degradation
Additives are absolutely essential in the development of commercial polymeric materials. Accordingly, an exhaustive control of composition and evolution in these additives over time is necessary to validate their performance and safety during their shelf life and, consequently, their ultimate applications. Gas chromatography coupled with mass spectrometry, GC–MS, is described in the present
Polymer Additives and Plasticizers Analytical Standards | Agilent
Plasticizers and polymer additives are widely used to improve the manufacture and performance of materials in desired end products. In some countries certain plasticizers, mainly phthalates, are banned, as these substances are suspected of causing a wide range of health issues.
Polymer Additives and Plasticizers Spectral Library
The Thermo Scientific Polymer Additives and Plasticizers library is a valuable addition to any polymer chemist's toolbox. It includes spectra of plastics and additives for polymers, rubbers, cosmetics, adhesives, sealants, and plasticizers. Eliminate guesswork in your spectral analysis and increase efficiencies in your lab.
Handbook of Plasticizers - 3rd Edition
Description. Handbook of Plasticizers, Third Edition, is an essential professional reference, providing information that enables R&D scientists, production chemists, and engineers the information they need to use plasticizers more effectively, and to avoid certain plasticizers in applications where they may cause health or material durability
Additives Analysis for Polymers and Plastics - Intertek
A multitude of polymer additives are added to commercial polymers in order to enhance performance and achieve various functional properties and accordingly demands stringent analytical expertise. Additive analysis for polymer materials can be challenging due to the complexity of the materials: the presence of various groups of additives, compounding ingredients, and fillers all in one sample.
- Can pyrolysis be used to identify organic plastic additives?
- Analysis of organic plastic additives (OPAs) associated to plastic polymers is growing. The current review outlines the characteristics and the development of (multi-step) pyrolysis coupled with a gas chromatography mass spectrometer (Py-GC/MS) for the identification and semi-quantification of OPAs.
- What is the standard protocol for the analysis of plastic additives?
- In the various studies on the analysis of plastic additives, two different approaches have been used. However, there is no established standard protocol to identify and quantify these compounds. Table 4. Py-GC/MS method parameters for the analysis of plastic additives in various studies. Cf. Table 1 for the corresponding compounds analysed.
- How to identify plastic additives in polymer materials?
- Although various analytical techniques can be used to identify plastic additives in polymeric materials, most laboratories and studies use wet chemical techniques to extract additives from the polymers. To date, many conventional methods for OPA analysis in polymer materials have been published.
- What is a chemist's Handbook for plastic & polymer additives?
- Handbook for the Chemical Analysis of Plastic and Polymer Additives, 2nd Ed. The Second Edition of this handbook provides the necessary tools for chemists to obtain a more complete listing of additives present in a particular polymeric matrix. This edition features:
- How difficult is quantitative analysis of plastic additives?
- Quantitative analysis is not easy to perform. The TD of plastic additives is influenced by the geometrical surface of the particle => Sampling problems for heterogenic materials. Difficult interlaboratory reproducibility of Py-GC/MS caused by various factors, including the materials and the different methods of pyrolysis and GC analysis.
- How is Py-GC/MS used to identify plastic additives in polymeric matrices?
- Py-GC/MS has been used to identify and sometimes semi-quantify plastic additives in polymeric matrices. In this section, we discuss the different steps involved in sample preparation before analysis and the importance of the various parameters in a Py-GC/MS method for adequate identification of the additives according to their chemical family. 3.1.
