Vulkalent® E/C

Vulkalent® E/C by Rhein Chemie Additives (Lanxess Group) is a highly effective retarder. It is considerably more powerful than retarders of the organic acid types, such as salicylic acid or phthalic anhydride. It is used to delay the onset of vulcanization. It enables the processing safety and scorch resistance to be controlled within wide limits without having to change the formulation. It also acts as a replasticizing agent and can be used to restore a flow time which has been reduced by heat or unsuitable processing can be increased. It is also effective in NBR, NR and SBR. It is suitable for tire compounds because its retarding effect on thiazole accelerators is exceptionally marked. It is also designed for the manufacturing of technical goods, footwear and molded goods, e.g. those produced by injection and transfer molding. Vulkalent® E/C has a shelf life of 547 days.
