Excellent lubricating properties. In addition, the fluorine-containing thermoplastic rubber essentially cures by simply cooling after molding without adding a vulcanizing agent like normal fluororubber, so there is no need to add a vulcanizing agent. There is no need to add other additives, but depending on the purpose, vulcanizing agents that are well known as fluororubber vulcanizing agents, such as organic peroxide compounds, polyhydroxy compounds, vulcanization accelerators, and polyamine compounds, may be used. added. When adding these additives 1i+t+: to fluorine-containing thermal I'iTwi rubber,
Known vulcanization methods can be used, such as Perogyzaidoka old style, polyol vulcanization, and polyamine vulcanization. Alternatively, a method of adding a photo- or heat-functional compound and curing with light or heat may also be adopted.
