a polyfunctional amine compound

Mainly used for special synthetic rubber, such as acrylic rubber and fluorine rubber cross-linking. Polyamine sulfide fluoride rubber is characterized by the mechanical strength of vulcanized rubber, compressed water for a long time deformation of small, high temperature long-term aging can still maintain good physical and mechanical properties, but easy to scorch, the processing safety adverse, and gradually developed a "closed Amine & quot; compounds, such as hexamethylenediamine carbamates, ethylenediaminocarbamates to improve process safety. When an amine is used as the vulcanizing agent, a metal oxide must be added. At this time, the metal oxide not only acts as an activator to accelerate the vulcanization reaction, but also the acceptor of fluorine generated in the sulfurization reaction than hydrogen.
