1,1-difluoro-2-iodoethylene FKM Fluorinated elastomers cross-linkable groups
Fluorinated elastomers have been widely used in recent years in the field of automotive parts, hoses, sealing materials and O-rings due to their outstanding chemical and mechanical resistance, good sealing properties at low and high temperatures, low solubility in oils, and especially resistance to alkaline additives.
1,1-Difluoro-2-iodoethylene, as a copolymer monomer that can introduce cross-linkable groups, can significantly improve the vulcanisation of fluorinated elastomers, so as to prepare vulcanised products with outstanding low-temperature resistance.
