Abstract
One embodiment of the present invention relates to an elastomer composition, a sealing material, or a method for producing a sealing material, in which the elastomer composition includes a crosslinkable fluoroelastomer (A1) that is other than a perfluoroelastomer and has a fluorine content of 69% by mass or more and a crosslinkable fluoroelastomer (A2) that is other than a perfluoroelastomer and has a fluorine content in a range of 55 to 68% by mass, and a content of the fluoroelastomer (A1) is 60 to 95% by mass based on 100% by mass of the total of the fluoroelastomers (A1) and (A2).
Claims7
An elastomer composition comprising:
- a crosslinkable fluoroelastomer (A1) that is other than a perfluoroelastomer and has a fluorine content of 69% by mass or more;
- and
- a crosslinkable fluoroelastomer (A2) that is other than a perfluoroelastomer and has a fluorine content in a range of 55 to 68% by mass,
- wherein a content of the fluoroelastomer (A1) is 60 to 95% by mass based on 100% by mass of a total of the fluoroelastomers (A1) and (A2), and
- wherein the fluoroelastomer (A2) is at least one compound selected from a vinylidene fluoride-propylene-tetrafluoroethylene polymer, an ethylene-tetrafluoroethylene-perfluoroalkyl vinyl ether polymer, and a vinylidene fluoride-tetrafluoroethylene-perfluoroalkyl vinyl ether polymer.
