Rhenogran CLD-80 N,N'-di-thio-bis (hexahydro-2H-azepinone-2) Rhein Chemie Catalysts / Accelerators / Vulcanizing agents >> Sulfur Rubber - Elastomer (Chloroprene, Butyl …) SEALANT Rhenogran® Triazine CLD-80 Non-staining sulphur donor for the vulcanization of natural and synthetic rubbers 80% Caprolactmadisulfide techn. [N,N'-di-thio-bis (hexahydro-2H-azepinone-2)] 20% elastomer binder and dispersing agents Under common curing conditions Rhenogran CLD-80 liberates free sulphur, which, in contrast to normal sulphur, forms mono and diether bridges. These are responsible for the excellent heat ageing resistance of Rhenogran CLD-80 vulcanizates. The blooming, generally observed when using thiuram disulphides as cross-linking agents is absent with Rhenogran CLD-80. The use of Rhenogran CLD-80 results in increased safety in scorch properties. When the full curing temperature is reached, a quick vulcanization follows. This rapid vulcanization is of particular advantage when voluminous moulded articles are produced. Moreover, compounds with Rhenogran CLD-80 provide an excellent broad curing plateau. Rhenogran CLD-80 is, therefore, especially suitable in all cases where high temperatures occur during the processing, e.g. salt vulcanization and injection moulding. Reversion effects are avoided. Vulcanizates show favourable compression set properties as well as low permanent elon-gation values. We recommended the use of Rhenogran CLD-80 wherever a high degree of heat-resistance is required. In many cases, the amounts of conventional antioxidants to be incor-porated can be reduced. articles resistant to reversion, based on NR, e.g. tyre carcasses; with additional thiuram accelerator for nitrile rubber seals; age-resisting articles, based on SBR, NBR, EPDM. Blend of caprolactamdisulfide, elastomer binder and dispersing agents. Used as a non-staining sulphur donor for the vulcanization of natural and synthetic rubbers with additional thiuram accelerator for nitrile rubber seals. Provides very good heat ageing resistance, absence of blooming, increased safety in scorch properties and very good broad curing plateau. Shows favourable compression set properties and low permanent elongation values.
