TDEC-75/70

TDEC-75/70 tellurium diethyldithiocarbamate Super accelerator TDEC-75/70 for NR and synthetic rubbers. It causes a high spped vulcanization of EPDM and IIR when used together with other accelerators of the thiazole, thiuram and dithiocarbamate class. Even used in small amounts of TDEC-75/70, it gives a shorter total curing time. The vulcanizates using TDEC-75/70 have high tensile strength, and good aging resistance. Additions of TDEC-75/70 are advantageous in soft compounds with a high oil content, since larger dosages of oil reduce the curing rate. Composition 70 % tellurium diethyldithiocarbamate, 30% EPDM/EVA binder and dispersing agents Appearance Orange granules Density,20 °C Approx. 1.23g / cm3(20°C) Physiological properties :See safety data sheet (MSDS) Raw material characteristics of TDEC : Melting point 108°C Evaporation loss ≤ 0.5% TDEC content ≥ 98% Sieve residue 63μm ≤ 0.5% Tellurium Content16.5 - 19.0 %Ash content≤ 0.3 % 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 TDEC is assured. TDEC-75/70 is used as an additional accelerator together with thiazole, thiuram and dithiocarbamate accelerators. For preventing blooming the dosage should not exceed 0.5 phr. It is broadly used in industrial goods, wires and cables, air bags tubes and rubberized clothes; and also used in automobile hoses, steam and acid resistant hoses, profiles.
