Features Of Eastman Diamylamine Rubber Accelerator

  1. High scorch safety for extended processing window in rubber compound mixing and extrusion.

  2. Excellent vulcanization efficiency, delivering fast cure rates without compromising physical properties.

  3. Good compatibility with natural rubber (NR), styrene-butadiene rubber (SBR), and butadiene rubber (BR).

  4. Low volatility and thermal stability suitable for high-temperature curing processes.

  5. Non-staining and non-blooming characteristics ideal for light-colored and premium rubber goods.

Typical Applications Of Eastman Diamylamine Rubber Accelerator

  1. Tire treads and sidewalls requiring balanced cure kinetics and aging resistance.

  2. Industrial rubber products including conveyor belts, hoses, and rolls.

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

  4. Footwear soles and outsoles demanding consistent crosslink density and abrasion resistance.

  5. Technical rubber goods where low compression set and high resilience are critical.
