PROPERTIES:


NBC is used as a secondary accelerator in most of the sulfur cured elastomers. It offers an effective antiozonant function in dynamic applications as well as a good antioxidant function in general.

APPLICATION:


NBC is an effective antiozonant in SBR, BR, CR, NBR and IIR compounds fir products used in dynamic applications shere a wax film might break down and therefore not be efficient.
It offers antioxidants in CR, CSM, CO, ECO and EPDM.
Furthermore, NBC is used for EPDM and CSM vulcanizates requiring high heat resistance and in colored CR articles where it Improved the resistance against sunlight exposure.
