Factory Supply Accelerator NOBS 102-77-2 richest-rubber
(1) NOBS is an excellent rubber accelerator. The performance of accelerator NOBS is similar as CZ with better scorch safety. (2) Accelerator NOBS is widely used in NR, IR, SBR, NBR and EPDM. (3) Accelerator NOBS can be used alone or with other vulcanization accelerators such as thiurams, guanidines and dithiocarbamates to improve the activity.
The most commonly identified allergen was 1,3-diphenylguanidine, far ahead of thiurams, which were previously described as the most sensitizing accelerators. The use of 1,3-diphenylguanidine-free gloves is recommended. No subject reacted to

Oct 15, 2016· MBT, MBTS and CBS are the more widely used thiazoles . Their use has increased in gloves during the last decade and MBT remains the most widely used accelerator for industrial rubber . MBT was found to be the most frequent sensitizer in
Accelerator, in the rubber industry, is added with a curing agent to speed the vulcanization. Accelerators contain sulfur and nitrogen like derivatives of benzothiazole and thiocarbanilides. The popular accelerators are sulfenamides (as a delayed-action accelerators), thiazoles, thiuram sulfides, dithocarbamates and guanidines.

Rubber Accelerator DPG D Used as a secondary accelerator with thiazoles and sulphenamides in NR and SBR Exhibits better storage stability compared to thiuram and dithiocarbamates but is not so active. DPG can be used in latex as secondary gelling agent (foam stabilizer) in the silico-flouride foam process.
