Rubber compounding ingredients — Carbon black — Determination of light transmittance of toluene extract
Preview
Summary
This document specifies a method for the determination of the light transmittance of the toluene
extract from carbon black for use in the rubber industry, as a means of measuring the discolouration
caused by the extractable matter.
The light transmittance value provides an estimate of the degree of discolouration caused by the
toluene-extractable matter present on the surface of the carbon black.
This method might not be applicable to carbon blacks with a high extractable-matter content.
