Features and Applications

Actmix IS90-70PR is a pre-dispersed vulcanizing agent for natural rubber and diene synthetic rubbers. Compared with ordinary sulfur, it is easy to disperse in rubber compounds, does not bloom, and does not penetrate into adjacent rubber layers. This is because it contains at least 90% modified polysulfur that is insoluble in carbon disulfide and other solvents. It is suitable for various occasions that require storage, rubber bonding and interlayer bonding. After mixing, it can avoid sulfur migration and blooming, thereby maintaining the storage safety of the rubber compound. To avoid the premature conversion of insoluble sulfur into soluble sulfur, it should be added just before the end of mixing, and the sulfur addition temperature should not be too high.
