Rheological Properties of Polydimethylsiloxane at Various Cure States

This paper discusses the rheological properties of semi-cured compounds of polydimethylsiloxane (silicone) rubber.By controlling cure time, compounds of various states of cure were prepared and then, using a Rubber Process Analyzer (RPA), frequency sweep tests were carried out on the prepared samples. Results obtained indicated that depending on the gel (sol) fraction of samples, each sample presented a particular behavior
