Vulkazon®

Non-staining antiozonants

Characteristics

Vulkazon® AFD, when used in conjunction with antiozonant waxes,is a very effective non- staining antiozonant for diene rubbers,though without antioxidant or anti-flex cracking effects. It can alsobe used without wax in the production of goods based on chloro-prene rubb er or blends of chloroprene rubber with IR or SBR.Vulkazon® AFS is used, with or without anti ozonant wax, mainly forchloroprene rubber. In other diene rubbers Vulkazon® AFS in con-junction with antiozonant wax is often consider ably less effectivethan the corresponding combinations consisting of Vulkazon® AFDand anti ozonant wax. Vulkazon® AFS has no antioxidant or anti-flexcracking effect.

Applications

Vulkazon® AFD is used with an antiozonant wax for light-coloredgoods that must not cause contact staining, e.g. profiles, seals, hose,cables and other products based on NR, IR, BR or SBR, and withoutwax for products based on CR.Vulkazon® AFS is particularly recommended for light-colored andnon-contact-staining goods (see above) based on CR.
