Cure-Rite® OBTS

Cure-Rite® OBTS is an effective and proven sulfenamide accelerator. Consumers will benefit from longer, delayed-action vulcanization in NR, NR-BR Blend, NR-SBR Blend, particularly when fine grade Carbon Blacks are used. OBTS is, typically, used in the range of 0.5-4.0 phr. Compared to CBS, OBTS offers better scorch protection, cure rate and state of cure. The long scorch delay allows OBTS to produce high value rubber with high modulus and excellent dynamic elasticity. OBTS is well-known for the production of thick cross-section tread vulcanizates and complex precision molded, injected or extruded goods.
