ABSTRACT:
Calcium aluminum hexahydrate is a useful curative-stabilizer for halogenated rubbers such as chloronated polyethylene, chlorosulfonated polyethylene and polychloroprene as it can yield vulcanizates free of leachable lead. Also, these vulcanizates with about 1 to about 30 or more parts with about 3 to about 15 parts calcium aluminum hexahydrate being highly desirable give satisfactory to improved heat ageing properties as well as oil ageing properties.
