Development of a novel cross-linking agent with excellent resistance to high-temperature vapour

Seals, such as elastomer O-rings, are used to prevent the leakage of vapour from the ductwork or devices through which it flows. The temperature of the vapour that is often present in industrial processes continues to increase. Therefore, there is a requirement for sealing materials that are proven to work under conditions that involve high-temperature vapour. This article describes the development of a cross-linking agent for perfluoroelastomer that has two features – resistance to high-temperature vapour and cross-linking efficiency.
