Polymer Filler Material
Analysis of Polymer Fillers and Colored Pigments

Polymeric materials have been widely used in various industry branches and daily life. Most of the polymeric materials are blended with further additives and filler materials to optimize the properties of the pure polymer matrix.

For the complete characterization of these composite materials not only the mid IR but also the far IR spectral range is of interest. The mid IR region (4000 cm-1 – 400 cm-1) offers valuable information about the composition and structure of organic compounds. In contrast, the FIR/THz region (below 400 cm-1) provides important information about lattice vibrations and vibrations of functional groups containing heavy atoms in inorganic ionic compounds.

Only the combined investigation in the far and mid infrared spectral range provides the optimum solution for the complete characterization of the modern polymeric materials. The unique Bruker FM technology for the VERTEX 70v and the INVENIO R FT-IR spectrometers covering the entire MIR-FIR/THz spectral range from 6000 cm-1 to 50 cm-1 (for INVENIO R 6000 cm-1 to 80 cm-1) in one single scan is the ideal tool for this application.

  • Only one measurement per sample for the complete MIR-FIR/THz spectral range

  • Additional information of the inorganic filler materials in polymers

  • Simple polymer identification by using the dedicated FIR-MIR library

Identification of the filler materials (two examples):
