Beschreibung
Zusammenfassung:	A sealing part formed a peroxide vulcanizate of a rubber compound having as a polymer component an EPDM mixture of 50 to 90 parts by weight of an EPDM having a Mooney viscosity (ML1+4 100 DEG C) of 35 to 55, and 50 to 10 parts by weight of a low-Mooney EPDM (a sub-polymer) having a Mooney viscosity (ML1+4 100 DEG C) of 5 to 25. The sealing part at the present invention has a high resistance to low-temperature compression permanent strain and is excellent in the kneadability of a rubber compound for producing the sealing part.
