Rhenogran® TMTD-70

Technical DataSheet | Supplied by Lanxess

Rhenogran® TMTD-70 by Lanxess is a tetramethylthiuramdisulfide. Used as an accelerator for the vulcanization of natural and synthetic rubbers. In combination with mercapto or sulfenamide accelerators the vulcanization undergoes retardation. In such cases they have little effect on the degree of cross-linking; they mainly reduce the scorch rate and increase total curing time. It receives an additional activation from basic accelerators, e.g. aldehyde-amine and guanidine. Rhenogran® TMTD-70 is used as a primary accelerator in combination with sulfur, as a secondary accelerator in conjunction with thiazoles, sulfenamides, carbamates and as a curing agent and sulfur donor without free sulfur. Sulfur-less cure or low-sulfur vulcanization is providing heat resistant vulcanizates with good ageing properties.
