Morphology and Performance of Hydrogen Polysiloxane Cross-linked RTV Silicone Rubber

In this article, two sorts of hydrogen polysiloxanes were added into vinyl silicone rubber as crosslinkers, and the effects of the crosslinkers on the mechanical, electric properties and vulcanization time were compared.The results indicate that the hydrogen polysiloxane with low hydrogen content improves the performance of the silicone rubber, more distinctively and the optimum comprehensive property was achieved as 4% wt hydrogen polysiloxane was added.
