Polymers are useful in a variety of applications because of the combination of polymer selection and the additive package. Without proper additives polymers do not process well and cannot withstand environmental exposures such as heat, oxygen, ozone, radiation, solvents, water, and stress.
Typically Additives Analysis is done to verify product conformance to a formula, compare competing products, determine cause of failure, or guide a development program.
We analyze the following:
Additives are removed from the sample and then the extraction solvent is typically analyzed using chromatography to separate the mixture of additives and a spectrometer to provide identification. Gas Chromatography (GC) and Liquid Chromatography (LC) are often used.
Inorganic additives are usually evaluated using Energy Dispersive Spectroscopy while acquiring Scanning Electron Microscopy (SEM/EDS) images to determine particle size and shape.
