Abstract

PROBLEM TO BE SOLVED: To obtain a HNBR composition by using an organic peroxide whose half time on crosslinking of HNBR is 1 min at >=190 deg.C. SOLUTION: The HNBR composition contains 0.1-7 pts.wt. of an organic peroxide whose half time on crosslinking of HNBR is 1 min at >=190 deg.C, based on 100 pts.wt. of HNBR. This enables the simultaneous improvements of pressure-resisting permanent stress and molding processability.
