Rubber formulated with soy filler offers environmental advantages.

We’ve reported many times on moisture content/”percent solids” measurements.  In principle, the measurement is simple.  Weigh an amount of a compound, then dry it out, then weigh it again.  And (as we’ve also reported) you can do it with an analytical balance.  If, however, you frequently make those measurements, you can make it easier on yourself with a moisture analyzer.  For example, for this work on using soy protein as a butyl rubber filler, the researchers used a moisture analyzer to measure the moisture content of the different rubber formulations.
