Component Analysis of Rubber

Print

Summary

Rubber contains not only the primary components such as dienepolymer and EPR but also rubber chemicals (vulcanizing agents, vulcanization accelerators, vulcanization accelerator aids, age resister, etc.) which are compounded and crosslinked. We are able to perform the analysis of the compounded components by using a wide variety of analytical equipment and selecting appropriate analytical methods.

Analytical method of the compounded components

Compounding component An example of analytical equipment to be used
Rubber component Fourier-transform infrared spectroscopy (FT-IR)
Field desorption mass spectrometry (FD-MS)
Rubber chemicals Gas chromatography/mass spectroscopy (GC/MS)
Field desorption mass spectrometry (FD-MS)
X-ray fluorescence analysis (XRF)
Inductively coupled plasma-atomic emission spectrometry (ICP-AES)
Fillers Fourier-transform infrared spectroscopy (FT-IR)
X-ray fluorescence analysis (XRF)
X-ray diffraction analysis (XRD)
Thermogravimetric analysiss (TGA)
Oil Gas chromatography/mass spectroscopy (GC/MS)
Field desorption mass spectrometry (FD-MS)
Thermogravimetric analysiss (TGA)
Carbon black Raman spectroscopy
Thermogravimetric analysiss (TGA)

Example of analysis: Analysis of components contained in rubber (thermogravimetry)

The amounts of the compounded components are determined from the weight reduction curve based on temperature changes.
