2-MERCAPTOBENZOTHIAZOLE
There are some types of rubber accelerators. They are used in combination with each other in accordance with vulcanizing and/or acid-base conditions. Some examples classified by chemical structure are as below; • Thiazole o 2-Mercaptobenzothiazole (CAS #: 149-30-4) o Dibenzothiazole disulfide (CAS #: 120-78-5)
