Standard Test Method for Rubber Compounding Materials—Free 2-Mercaptobenzothiazole (MBT) in Benzothiazyl Disulfide (MBTS)

Importancia y uso:

4.1 2-Mercaptobenzothiazole (MBT) is usually the major impurity in MBTS. Free MBT may be determined by this test method.

4.2 MBT and MBTS are used for rubber and latex vulcanization acceleration. The amount of MBT in MBTS may be of importance in predicting performance in rubber compounds and for raw material purchase and control.

4.3 This test method may be used as a quality control tool and for research and development work.
