Industrial Applications

This accelerator is primarily employed in the vulcanization of natural rubber, synthetic rubber, and reclaimed rubber compounds. It is particularly valued in the production of non-food rubber products such as automotive tires, industrial hoses, electrical cables, and rubber footwear. When compared to accelerator M, MBTS offers a higher vulcanization critical temperature, typically around 130°C, which provides processors with a longer scorch safety margin during mixing and extrusion operations. This characteristic makes it an ideal choice for complex manufacturing processes where delayed action is beneficial.

Quality Assurance and Handling

Our manufacturing facility adheres to strict quality control protocols to ensure every batch meets international standards. Each shipment is accompanied by a comprehensive Certificate of Analysis (COA) verifying purity and physical properties. For optimal storage, the product should be kept in a ventilated, low-temperature, and dry environment to prevent degradation. Stability is maintained under normal temperatures and pressures, but standard industrial safety precautions should be observed during handling. We support global logistics and provide technical documentation to facilitate seamless integration into your production formulations.
