Tellurium Content 16.5 - 19.0 % Ash content ≤ 0.3 % Use Characteristics: Super accelerator HiDispersion® TDEC-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 HiDispersion® TDEC-70, it gives a shorter total curing time. The vulcanizates using TDEC-70 have high tensile strength, and good aging resistance. Additions of HiDispersion® TDEC-70 are advantageous in soft compounds with a high oil content, since larger dosages of oil reduce the curing rate.
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 TDEC is assured.
Dosage levels: HiDispersion® TDEC-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.
Applications: 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.
Packing: Net25 kg cartons with plastic inner.
Storage stability: In original closed containers under cool and dry conditions max. 2 years.
Handling: Consult material safety data sheet (MSDS) for additional handling information. Uses : 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. Synonyms : no data
