novel sulfenamide accelerators and rubber for indonesia
Novel Sulfur Vulcanization Accelerators Based on Mercapto
Sulfur vulcanization accelerators derived from 2-mercaptobenzothiazole (MBT) have been a staple for the rubber processing industry for over 65 years. Most noteworthy are the sulfenamide derivatives, which provide various combinations of scorch delay and cure rate, depending upon the basicity and steric nature of the sulfenamide N-substituent(s).

The thermal decomposition of sulfenamide accelerators
The thermal decomposition of three sulfenamide accelerators N‐cyclohexylbenzothiazole sulfenamide (CBS), 2‐(4‐morpholinothio) benzothiazole (MOR) and 2‐t‐butylaminobenzothiazole sulfenamide (TBBS) were investigated by differential scanning calorimetry.The sulfenamides decompose rapidly at 210–220°C, yielding a number of products, including reactive polysulfidic complexes.

ACCELERATOR TMTD - MG
TMTD-MG is a very active, sulfur-bearing, non-discoloring rubber accelerator for use in NR, SBR, NBR, EPDM and other rubber elastomers or blends. For most compounding applications, TMTD-MG requires the addition of zinc oxide and a fatty acid for effective use. Sulfur is not required but is often used.
