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.
APPLICATION:
Vehicle and building seals, vehicle hoses, steamproof & acidproof hoses, cable jacket, insulated products.
DOSAGE:
Max 0.5 phr to avoid blooming.
PACKING & STORAGE:
Net weight 25kg/PE bags lined carton; Net weight 600 kg/pallet.
Shelf-life: 1 year in its original packaging.
Stored in a dry and cool place.
Compared to traditional TDEC powders, YLSCH-RBB®TDEC-75GE 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.
