Investigation of Additives in Plastics by FTIR-ATR Spectroscopy

Commercially available plastic products contain polymers, such as polyethylene (PE) and polypropylene (PP), as their main components, in addition to various trace component s that are added to enhance performance and maintain quality. This application note introduces an evaluation of additives used in plastic bags taking advantage of the high S/N ratio of the Shimadzu FTIR IRTracer-100 spectrophotometer.
