Features Of LAN-XESS Rhenogran CBS Accelerator

  1. High scorch safety with delayed onset of vulcanization, enabling extended processing time during mixing and extrusion.

  2. Excellent cure rate and final crosslink density, delivering superior tensile strength and heat resistance in finished rubber products.

  3. Low volatility and thermal stability, minimizing fume generation and ensuring consistent performance in high-temperature curing cycles.

  4. Good dispersibility in natural rubber (NR), styrene-butadiene rubber (SBR), and butadiene rubber (BR) compounds.

  5. Complies with REACH and RoHS regulations, supporting sustainable and compliant rubber manufacturing.

Typical Applications Of LAN-XESS Rhenogran CBS Accelerator

  1. Tire treads and carcasses for passenger and commercial vehicle tires.

  2. Industrial rubber goods including conveyor belts, hoses, and rollers.

  3. Automotive non-tire components such as engine mounts, bushings, and vibration dampers.

  4. Technical rubber articles requiring balanced cure profile and aging resistance.

  5. Footwear soles and molded rubber parts demanding reproducible vulcanization behavior.
