Features Of Rhein Chemie Rhenogran CBS-80 Accelerator

  1. Controlled scorch safety with delayed onset of vulcanization, minimizing premature curing during processing.

  2. Excellent state-of-cure development for high crosslink density and superior tensile strength in final products.

  3. Uniform dispersion in rubber compounds due to its granular masterbatch form (CBS pre-dispersed in EPDM carrier).

  4. Reduced dust generation and improved handling safety compared to conventional CBS powder.

  5. Consistent performance across batch-to-batch production, ensuring reproducible cure characteristics.

Typical Applications Of Rhein Chemie Rhenogran CBS-80 Accelerator

  1. Tread and sidewall compounds for passenger car and truck tires.

  2. Industrial rubber goods including conveyor belts and hoses.

  3. Automotive dynamic components such as engine mounts and bushings.

  4. General-purpose SBR and NR-based technical rubber articles.

  5. Retreading compounds requiring reliable re-vulcanization behavior.
