HYDROGENATED NITRILE RUBBER-BASED SEAL MOLDING MATERIAL FOR R152a AND R134a

摘要

PROBLEM TO BE SOLVED: To provide a seal molding material excelling in resistance to both refrigerants R152a and R134a and to any refrigerator oil, assembling oil, and the like used for the refrigerants.;SOLUTION: This hydrogenated nitrile rubber-based seal molding material for R152a and R134a contains 60-150 pts.wt. of white carbon with a specific surface area of 30 to 200 m²/g (measured by a nitrogen adsorption method), 0.1 to 5 pts.wt. of a silane coupling agent and 0.5 to 10 pts.wt. of an organic peroxide to 100 pts.wt. of hydrogenated nitrile rubber having a bonded acrylonitrile content of 31 to 45 wt.%.;COPYRIGHT: (C)2009,JPO&INPIT
