NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of supplying advanced chemical solutions. Today, we embark on a detailed exploration of Accelerator NOBS (CAS 102-77-2), dissecting its synthesis, understanding its properties, and highlighting its profound impact on the rubber industry.

Synthesis of Accelerator NOBS:

The production of Accelerator NOBS typically involves the oxidative condensation of 2-mercaptobenzothiazole with morpholine. Common methods employ oxidizing agents like sodium hypochlorite. The reaction is a key step in creating this specialized chemical. While the detailed industrial synthesis is proprietary, understanding the core reactants – mercaptobenzothiazole and morpholine – highlights its chemical family and origins, positioning it within the broader landscape of rubber chemical auxiliaries.

Key Properties of Accelerator NOBS:

  • Appearance: Typically presented as light yellow to brown granules or powder.
  • Odor: A mild, often described as sweet or amine-like odor.
  • Solubility: Soluble in organic solvents like acetone, benzene, and methanol; largely insoluble in water.
  • Melting Point: Generally falls within the range of 78-80°C, indicating its stability at typical ambient temperatures but readiness to react at processing temperatures.
  • Density: Ranges from 1.34 to 1.40 g/cm³, providing information for formulation calculations.
  • Delayed Action: Its most significant property is the delayed onset of vulcanization activity, providing crucial scorch safety.
  • Activity: Serves as an effective vulcanization accelerator, particularly when used with synergistic secondary accelerators.

Industrial Impact and Applications:

The industrial significance of Accelerator NOBS cannot be overstated. Its primary role is to accelerate the sulfur vulcanization of natural and synthetic rubbers, leading to improved physical and mechanical properties. Key applications include:

  • Tire Manufacturing: Essential for achieving the correct cure rates and properties in tire components, ensuring durability and performance.
  • Industrial Rubber Goods: Used extensively in the production of conveyor belts, hoses, seals, and gaskets, where resistance to wear and environmental factors is critical.
  • Footwear: Contributes to the longevity and resilience of rubber soles and other shoe components.
  • Molded and Extruded Products: Its versatility makes it suitable for a wide array of general rubber goods requiring precise manufacturing and lasting performance.

The ability of NOBS to improve bin stability and allow for safer processing at higher temperatures makes it a valuable asset for manufacturers aiming for efficiency and quality. When users seek to buy rubber accelerator NOBS, they are investing in a product that demonstrably enhances manufacturing processes and the performance of the final rubber article.
