J. Graham et al., RAPID IDENTIFICATION OF PLASTICS COMPONENTS RECOVERED FROM SCRAP AUTOMOBILES, Plastics, rubber and composites processing and applications, 24(2), 1995, pp. 55-67
The application of mid-infrared reflection spectroscopy to the identif
ication of non-metallic components recovered from automobile scrapyard
s is described. Identification of all the polymers used in the car ind
ustry can be achieved reliably in less than 10 s per identification. T
he method does not require that samples be removed from the component.
