the best sulfur donor vulcanizing agent 4, 4 in germany
curing with sulfur and sulfur donor systems
temperature can be used as vulcanizing agents. These are called sulfur donors. Generally sulfur donors convert initially formed polysulfides to monosulfides which is characteristic for EV and semi-EV systems . A few sulfur donors are given in Fig. 4 which includes Akrochem Accelerator R (DTDM), which can directly substitute sulfur .

9.5.2 Vulcanizing Agents. Three vulcanizing agents find extensive use in the rubber industry: sulfur, insoluble sulfur, and peroxides. The chemistry of peroxides has been reviewed in Chapter 7. Rhombic sulfur is the most common form of sulfur used in the rubber industry and, other than normal factory hygiene and operational procedures, does not require any special handling or storage.

Sulfur vulcanization
Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins. Even with natural rubber, large amounts of sulfur as well as high temperatures and long heating periods are necessary, with the end products often being of an unsatisfactory quality.
