Additives, such as plasticizers, processing aids, softeners, extenders, and fillers, serve a variety of purposes in a material or compound recipe. They can increase flexibility or processability and impact the compounding process and final product performance. While there are many types to choose from, the compatibility of the filler with the elastomer or polymer must be assessed to avoid bleeding or other issues with the cured system.

Gas chromatography – mass spectrometry (GC-MS) is a common method used to evaluate the presence and quantity of additives, plasticizers, and other specific ingredients in compounds. It can also identify unknown substances in a sample by comparing results to commonly known chemical “fingerprints.”
