Pre-dispersed Chemicals TDEC-75 Slab form

Pre-dispersed Chemicals TDEC-75 Slab form

Tellurium diethyldithiocarbamate
C20H40N4S8Te
M.W.: 720.68
CAS: 20941-65-5
EINECS: 244-121-9

PROPERTIES:
   TDEC combined with thiazoles, thurams and dithiocarbamates accelerators can accelerate sulfuration of EPDM and IIR. A little TDEC can shorten the sulfuration time. Moreover, it is particularly suitable for high oil content soft rubber compounds such as low-hardness solid EPDM seals or spongy seals due to reduction of sulfuration rate by a great deal of softening oil.

DOSAGE:
Max 0.5phr to avoid blooming.
APPLICATIONS:
Vehicle and building seals, vehicle hoses, steamproof & acidproof hoses, cable jacket, insulated products.


TYPICAL VALUES:
Initial melting point: 108℃
Purity: Min 98%
Tellurium content: 16.5-19.0%
Heating loss content: Max 0.5%
63μm sieve residue: Max 0.5%

Compared to traditional TDEC powders, Actmix TDEC-75PE F140 allows:

Dust free products with a complete filtration up to 100µm, no skin sensitization, health guard of operators.

Effective guarantee of activity of TDEC due to pre-dispersed masterbatch.

Tack free products at room temperature, convenience and accuracy on ingredients.

Lower Mooney viscosity at lower temperature (50℃), higher quality of dispersion.

Impurity free, blocked filter free of extrusive products, scrap rate reduction and higher productivity thanks to filtration.

Wider compatibility with other elastomers.
