Cure-Rite® BBTS Rubber Accelerator

Cure-Rite® BBTS is our first-choice, general purpose, sulfenamide (sulfur donating) rubber vulcanization accelerator. When using Cure-Rite BBTS, manufacturers benefit from fast, zero nitrosamine vulcanization in a broad variety of elastomers. It is fast acting, but also offers delayed action vulcanization, ensuring the development of desirable properties before curing while maximizing productivity. Rubber applications include natural rubber (NR), styrene-butadiene rubber (SBR), nitrile-butadiene rubber (NBR), and butadiene rubber (BR).

Compounders appreciate that Cure-Rite BBTS is added at the end of the mixing cycle and easily disperses in all rubber. Compared to CBS, Cure-Rite BBTS offers better scorch protection at typical loadings (0.5-4.0 phr). Cure-Rite BBTS also has excellent technical and economic synergy with Cure-Rite 18, enabling manufacturers to vary crosslink length and vulcanizate properties.
