Analysis of Black Rubber by FTIR and Thermogravimetry

Introduction

In Application News No. A406, we introduced the analysis of a black rubber diaphragm by FTIR and EDX, and in Application News No. 304, we introduced the analysis of rubber by the single reflection ATR method using FTIR. ATR measurement is easy to conduct, and accordingly, it is used to analyze a variety of samples. In particular, this method is widely used for analysis of rubber-related samples. However, as touched upon in the above-mentioned Application News articles, carbon black is added to many rubber products as a reinforcing agent, and this carbon black has a large effect on measurement results. Here we introduce an analysis of black rubber with added carbon black, focusing on the amount of carbon black that was added.
