this may be desirable for high resilience or for good dimensional sta- bility. the accelerator which has been most widely used with metal oxide cures is ethylenethiourea (etu) or 2-mercaptoimidazoline. further extensive use of etu in the vulcanization of cr is somewhat in doubt since it is a suspected carcinogen.

- Does vulcanizing system type affect curing properties?
- The effect of vulcanizing system type on curing characteristics, static mechanical properties (tensile strength, elongation-at-break, hardness and resilience), dynamic mechanical properties and thermal properties of reclaimed ground tire rubber was investigated.
- How do I select a vulcanizing accelerator?
- The selection of an accelerator will depend on the specific vulcanizing system and curing properties. Explore the classification of accelerators, the checklist to select the right accelerator based on the specific vulcanizing systems and curing properties.
- What is Accelerated vulcanization of rubber?
- The chemistry of the accelerated vulcanization of BR, SBR, and EPDM appears to have much in common with the vulcanization of natural rubber: Before the formation of crosslinks, the rubber is first sulfurated by accelerator-derived polysulfides (Ac-S~-Ac) to give macromolecular, polysul- fidic intermediates (rubber-Sx-Ac).
- What determines vulcanization rate?
- The accelerator determines the rate of vulcanization, whereas the accelerator to sulfur ratio dictates the efficiency of vulcanization and, in turn, the thermal stability of the resulting vulcanizate. Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur.
