  • Sulfenamide accelerators for improved network stabilization of rubber vulcanizates
    Patent number: 8110634
    Abstract: Sulfenamide derivatives of 4-alkyl substituted 2-mercapto benzothiazole (4m-MBT) as accelerators used in vulcanizable rubber composition having improved ‘Reversion Resistance’ and ‘Modulus & Hardness Stabilization’ properties for sulphur vulcanized tire compounds predominantly based on Natural Rubber or its blends with Polybutadiene (BR) and styrene butadiene rubber (SBR) in which Natural Rubber is the major component thereby improving the overall tire performance, ride safety and tyre service life.
    Type: Grant
