Material Identification Services | Polymers


Material identification is often used to validate the composition of a supplier's products used in manufacturing of components. Determining the molecular chemistry of non-metallic materials is primarily accomplished using FTIR and Micro-FTIR Spectroscopy. 

FTIR is one of the most important techniques used in the identification and analysis of polymers. Typical applications of FTIR in polymers include:

  • Identification of the polymer type to ensure that the correct type of polymer has been used. 
  • To investigate the composition of copolymers and polymer blends.
  • To investigate and identify polymer degradation mechanisms.
  • To identify substances that have migrated to the surface of the polymer.

Positive Material Identification (PMI) is the analysis of a material, this can be any material, but is generally used to establish composition by reading the quantities by percentage of its constituent elements. Typical methods for PMI include X-ray fluorescence (XRF) and optical emission spectrometry (OES)
