Application: Used for NR, IR, SBR, NBR, HR and EPDM.One of the mainly used acidic accelerators currontly and a medium fast primary accelerator. Imparts excellent aging properties, when used both alone and in combination with DM, TMTD and many others, mainly basic accelerators for higher activity.
secondary accelerator to derive maximum levels of processing safety and vulcanization rate. ThiazoleTypes Raw materials for thiazoles are aniline, carbon disulfide, and sulfur. The chief thiazole accelerators are 2-mercaptobenzothiazole (MBT), benzoth-iazole disulfide (MBTS), and the zinc salt of 2-mercaptobenzothiazole.
WESTCO™ MBTS Accelerator Benzothiazole disulfide CAS# 120-78-5 WESTCO™ MBTS accelerator for rubber is a general purpose accelerator for sulfur cures. It is very active above 142°C (287°F). Unlike thiuram disulfides, WESTCO™ MBTS does not split off active sulfur during vulcanization.
PROPIEDADES El VULMIC MBTS actúa como acelerador primario o como modificador de "scorch" cuando se utiliza como acelerador secundario en caucho natural y en Estireno-Butadieno. Es un acelerador de excelente seguridad y con velocidad de vulcanización moderada aunque vulcaniza rápidamente a temperaturas superiores a los 140 °C.
ACCELERATOR MBTS by Akrochem is a 2,2' Dibenzothiazyl Disulfide grade is used organic accelerator. It is non-staining and very active at temperatures above 280°F. It requires zinc oxide, fatty acid and sulfur. It is activated by aldehyde amines, dithiocarbamates, alkaline and basic materials; guanidines and thiurams.

Vulcanization & Accelerators Vulcanization is a cross linking process in which individual molecules of rubber (polymer) are converted into a three dimensional network of interconnected (polymer) chains through chemical cross links(of sulfur).
WESTCO™ MBT Accelerator Mercaptobenzothiazole CAS# 149-30-4 WESTCO™ MBT is a primary accelerator for natural and synthetic rubbers with excellent low temperature curing properties. It may be used in non-staining and non-black vulcanizates. It provides anti-scorch protection in …
MBT is widely used in industry and in articles. MBT is primarily used in the rubber industry as a non-volatile vulcanisation accelerator. MBT is also used as an intermediate in the production of other accelerators, some of which may decompose during vulcanisation and form MBT (BUA 1997).
Vocol ZBPD is a fast curing secondary accelerator for NR and EPDM. MAJOR APPLICATIONS AND PROPERTIES - Vocol ZBPD is mainly used as an accelerator in non-blooming, relative low cost, fast curing systems for EPDM. - When used in combination with Perkacit MBTS or sulfenamides in NR compounds, Vocol ZBPD dramatically improves reversion resistance.
