Features Of LAN-XESS Rhenogran TBBS-80 Accelerator

  1. High scorch safety with delayed onset of vulcanization, enabling extended processing time in high-temperature mixing and extrusion.

  2. Excellent state-of-cure development, delivering optimal tensile strength, modulus, and crosslink density in sulfur-cured NR, SBR, and BR compounds.

  3. Free-flowing granular form ensures consistent dosing, reduced dust generation, and improved operator safety versus powder alternatives.

  4. Thermally stable formulation minimizes premature decomposition during storage and processing, supporting reliable batch-to-batch performance.

  5. Compatible with standard sulfur vulcanization systems, including conventional, semi-efficient (SEV), and efficient (EV) cure packages.

Typical Applications Of LAN-XESS Rhenogran TBBS-80 Accelerator

  1. Passenger and truck tire treads and sidewalls requiring balanced cure rate and aging resistance.

  2. Industrial rubber products such as conveyor belts, hoses, and rubber rollers demanding high fatigue resistance and dimensional stability.

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

  4. Footwear soles and technical footwear compounds where processing safety and final elasticity are critical.

  5. General-purpose molded and extruded rubber goods for construction, agricultural, and material handling equipment.
