Mixland New Gen CBS 80 G

This is a medium fast primary sulfonamide accelerator for NR, IR, BR and especially SBR, combining a fast cure with a delayed action. It has the ability to provide fast efficient mixing of difficult, highly loaded carbon black reinforced compounds, without sacrificing scorch safety or physical properties. Its vulcanizates have good heat ageing and tear resistance. The product is used alone or can be boosted by small additions of other accelerators: thiurams or guanidines, to adjust and optimise the scorch / cure relationship for particular application conditions. It shows a good dispersion and a high degree of processing safety. It allows prolonged and difficult high-temperature mixing and manufacturing processes to be carried out without problems due to scorch; yet at 135 -150° C it still produces a fast cure effect.
