Abstract: An elastomeric fluoropolymer includes the following monomer units: about 45 mol % to about 65 mol % —CF2—CH2—; about 8 mol % to about 30 mol % —CF2—CF2—; about 4.5 mol % to about 25 mol % —CF2—CF(O—CF3)—; and about 6 mol % to about 20 mol % —CF2—CF(O—CF2—CF2—O—(CF2—O)n—CF3)—, where n is 1 or 2. In some embodiments, a composition includes an elastomeric fluoropolymer and at least one additive. In some embodiments, a composition includes a first elastomeric fluoropolymer and a second elastomeric fluoropolymer blended with the first elastomeric fluoropolymer. The first elastomeric fluoropolymer includes the following monomer units: about 45 mol % to about 65 mol % —CF2—CH2—; about 8 mol % to about 30 mol % —CF2—CF2—; about 4.5 mol % to about 25 mol % —CF2—CF(O—CF3)—; and about 6 mol % to about 20 mol % —CF2—CF(O—CF2—CF2—O—(CF2—O)n—CF3)—, where n is 1 or 2.
