Hidispersion Rubber Accelerators NURCHEM ZBEC-70 NURCHEM ZBEC-70

C30H28N2S4Zn

M.W. : 610

CAS : 14726-36-4

EINECS : 238-778-0

 

PROPERTIES:

NURCHEM ZBEC-70 is an ultrafast dithiocarbamates accelerator which can produce no nitrosamine and a primary or secondary accelerator for natural and synthetic rubber such as EPDM, IR, SBR, NBR, IIR, etc. Compared to traditional dithiocarbamates accelerators, NURCHEM ZBEC-70 has higher processing safety. It can activate thiazoles or sulfenamides and can be activated by alkaline accelerators. Vulcanizate accelerated by NURCHEM ZBEC-70 has similar tensile strength to that accelerated by other dithiocarbamates when dosage is same.

Compared to a traditional ZBEC powders , NURCHEM ZBEC-70 allows :

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

l Effective guarantee of activity of NURCHEM ZBEC-70 due to pre-dispersed masterbatch.

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

l Lower Mooney viscosity at lower temperature(50°C), higher quality of dispersion.

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

l Wider compatibility with other elastomers.
