Key Features & Advantages
Delivers fast vulcanization at curing temperatures, significantly reducing production cycle times and enhancing manufacturing efficiency.
Offers excellent scorch safety with delayed action, providing ample processing time and preventing premature curing during mixing and extrusion.
Produces vulcanizates with superior physical properties, including high tensile strength, good elasticity, and excellent aging resistance.
Versatile compatibility with natural rubber and synthetic polymers like SBR, BR, and NBR, ensuring broad application flexibility.
Generates relatively non-staining and non-discoloring vulcanizates, making it suitable for both black and light-colored rubber products.
