ULTRA/SECONDARY ACCELERATORS: accelerators and ZDMC ZDBCX

By far the most popular ultra/secondary accelerators are the dithiocarbamates and thiurams. The ultra/secondary accelerators often produce scorchy, very fast curing compounds. Their major functions are that they produce increased cure rate (i.e. raise the modulus) and shorten scorch times.

Effects of accelerators on the cure characteristics

Thiazole-based accelerators are the most widely used type, among which mercaptobenzothiazole disulphide (MBTS) is the most prominent [8]. Compared with other accelerators, MBTS presents the greatest processing safety, has a satisfactory cure rate and provides rubber compounds with good aging properties [9].

RAW MATERIALS AND COMPUNDS IN RUBBER INDUSTRY

Isoprene rubber (IR) is the synthetic counterpart of NR, but the properties of IR are significantly different from the properties of NR. It is mainly used in combination with other general purpose rubbers. Styrene-Butadiene rubber (SBR) is by far the most important synthetic rubber and widely used in tire applications.

Replacing TMTD with Nitrosamine Free TBzTD- Accelerator

TMTD is very widely used as a primary and sulphur donor-standalone accelerator in traditional sulphur curing systems. Due to secondary amine contents in TMTD, it produces Nitrosamine during its use. TBzTD is again of same thiuram group accelerator but without secondary amine, which results into Nitrosamine free cure.
