| 26780-96-1 |
 |
Used for NR, IR, BR, SBR, NBR and CR.
Effective against general aging especially by heat but not against flex-cracking.
Excellent antiozonant for CR. Less blooming and no influence on vulcanizing action but strong accelerating power for CR.
Suitable for tire carcases, tubes insulated electric wires and belts such as products required heat resistance.
Expected superior results for brake lining, air bags and steam hoses by increasing used quantity(about 5 phr). |
