Abstract

Provided area perfluoroelastomer composition containing a perfluoroelastomer and a compound having a perylene skeleton, in which the compound having a perylene skeleton is a compound other than perylene and 3,4,9,10-perylenetetracarboxylic acid diimide; and a sealing material containing a crosslinked product of the perfluoroelastomer composition.

Claims (7)

1. A perfluoroelastomer composition comprising:

a perfluoroelastomer; and

a compound having a perylene skeleton selected from the group consisting of

wherein R 1 and R 2 each independently represent an optionally substituted alkyl group, alkoxy group or aryl group, and

a content of the compound having a perylene skeleton is greater than or equal to 0.05 parts by weight and less than or equal to 0.4 parts by weight with respect to 100 parts by weight of the perfluoroelastomer.

2. The perfluoroelastomer composition according to claim 1 , wherein the perfluoroelastomer does not contain an inorganic filler.

3. A sealing material comprising a crosslinked product of the perfluoroelastomer composition according to claim 1 .
