Use Characteristics     Pre-dispersion TBzTD-70 rubber accelerator, make the vulcanization of natural and synthetic rubbers with a high level of processing safety. Pre-dispersionTBzTD-70 forms no carcinogenic nitrosamines within the definition of TRGS 552. The addition of mercapto or sulfenamide accelerators slows the vulcanization process. Scorch and vulcanization times are reduced. The degree of cross- linking is not greatly affected.  Basic accelerators such as aldehyde-amine and guanidine have an additional activating effect.  HiDispersion® TBzTD-70 is used as a primary accelerator in the presence of sulfur, as a secondary accelerator with thiazoles and as a sulfur-free vulcanizing agent. Cross-linking without free sulfur or low-sulfur cross-linking produces extremely heat-resistant vulcanizates with good aging characteristics.

Processing Advantages   The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easily and quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective TBzTD is assured.
