2,2-Dibenzothiazole disulfide

C14H8S4N2
M.W. : 332.5
CAS : 120-78-5
EINECS : 204-424-9

PROPERTIES:
NURCHEM MBTS-75 is a general quasi-ultrafast accelerator with excellent processing safety which can be used alone or combined with other accelerators. NURCHEM MBTS-75 together with dithiocarbamates can avoid scorching. Thiurams, dithiocarbamates and aldehyde-amines can activate NURCHEM MBTS-75. It is a retarder for processing and vulcanization of CR compounds. It can improve processing safety with ultrafast accelerators. Its vulcanizate has an excellent heat-ageing resistance.

Compared to a traditional MBTS powders , NURCHEM MBTS-75 allows :
l. Dust free products with a complete filtration up to 100μm, no skin sensitization, health guard of operators.
2. Effective guarantee of activity of NURCHEM MBTS-75 due to pre-dispersed masterbatch.
3. Tack free products at room temperature, convenience and accuracy on ingredients.
4. Lower Mooney viscosity at lower temperature(50°C), higher quality of dispersion.
5. Impurity free, blocked filter free of extrusive products, scrap rate reduction and higher productivity thanks to filtration.
6. Wider compatibility with other elastomers.
