Suggestions for the use of vulcanising agents for fluoroelastomers

Vulcanisation is the production of a certain degree of cross-linking of fluoroelastomer to give it good performance in use. Vitrification of fluoroelastomers can be carried out by ionic addition of nucleophilic reagents, or by peroxide or rays in the form of free radicals. Amine compounds (1 #, 3 # vulcanising agent) vulcanisation of fluoroelastomer can solve the general requirements of the product; the use of 2 # vulcanising agent, can solve the processing of the paste. In sealing products, in order to make it have a small compression deformation value, should be preferred to use phenolic compounds as vulcanising agent. Such as hydroquinone, bisphenol A, bisphenol AF, etc., and with the corresponding accelerator to adapt to the high-level performance requirements. In solving the resistance to corrosive media, it is recommended to use peroxide vulcanised fluorine rubber.
