Reduction of the adhesion level will occur if certain compounding ingredients are not avoided. The acceleration system has a direct effect on the adhesion level dibenzothiazole disulphide (MBTS) gives the highest adhesion levels. If a second accelerator is used, e g., tetramethyl thiuram disulphide (TMTD) or diphenyl guanidine (DPG), then the adhesion is significantly affected. Other ingredients which cause problems are plasticisers and process oils. [Pg.139]

The chemistry of the vulcanization of rubber is complex. The reaction of rubber with sulfur is markedly expedited by substances called accelerators, of which those commonly known as mercaptobenzothiazole and tetramethyl-thiuram disulfide are examples ... [Pg.1429]

Whereas Redfern [57] has pointed out the advantages of simultaneous thermal analysis techniques (particularly TG-DSC and TG-DTA) over techniques conducted singly, an even more complete thermal profile is provided when a thermal analyser is coupled to some form of gas analyser (MS or FTIR). Mohler and co-workers [51] have reported TG-DSC-MS of the thermal decomposition of the vulcanisation accelerator tetramethyl thiuram disulphide (TMTD) in rubber degradation of TMTD starts at about 155 °C, as evidenced by m/z 76 (CS2) and 44 (radical of the secondary dimethylamine).

However, 1,3-dithioles can be rearranged to 1,6,6aA4-trithiapentalenes, catalyzed by various sulfur-containing compounds, such as 1,2-dithiole-3-thiones,201 thioacetamide,202 phosphorus pentasulfide, elemental sulfur, dibenzylthiocarbamate, 2-mercaptobenzothiazole and tetramethyl thiuram-disulfide.203 (Scheme 14). This mechanism, however, cannot account for the... [Pg.96]

The rising of the rate of chemical reactions between sulfur and rubber, acceleration of the vulcanization, and reduction of its temperature are accomplished using special accelerators. The use of a few accelerators may improve the vulcanization process because of their mutual activation. Two accelerators were used tetramethyl-thiuram-disulhde (thiuram-D) and CAPTAX . They act mutually and thus improve the vulcanization process and the resulting properties of RubCon. [Pg.28]
