Influence of different types and amounts of crosslinking agent on the curing process of silicone rubber

Abstract

In this investigation, a high-consistency rubber was mixed with five different types and amounts of curing agent. After mixing, the raw material was characterised using a rubber process analyser. The results led us to the conclusion that silicone rubber could be crosslinked with a wide range of curing agents based on organic peroxides. A large amount of curing agent is not necessary to achieve higher values in terms of the elastic torque, or to accomplish a shorter processing time. It was able to show that the crosslinking density according to δ S’ is on a similar level throughout a range of curing temperatures.
