2-Mercaptobenzothiazole CAS 149-30-4 MBT

2-Mercaptobenzothiazole (also known as Accelerator M or Accelerator MBT, also known as fast-heating powder) is a general-purpose vulcanization accelerator for rubber. It has the characteristics of fast vulcanization acceleration, low vulcanization flatness, and no early vulcanization during mixing, and is widely used in the rubber processing industry.
