the effect of accelerators on vulcanization of natural rubber,accelerators and the ratio of sulfur-accelerator have a different effect on the value of hardening of rubber and its mechanical properties (ismail et al. 2003; fan et al. 2001; pongdhorn et al. 2001). nr has high rate of cross-linking along vulcanization. natural rubber provides a good interference with other non-polar rubber because

vulcanization accelerators for tyre manufactures
vulcanization accelerators vulcanization is a cross linking process in which individual molecules of rubber (polymer) are converted into a three dimensional network of interconnected (polymer) chains through chemical cross links(of sulfur). the vulcanization process was discovered in 1839 and the individuals responsible for this discovery were

- Is TBBS a good choice for vulcanizing Nr/EPDM blend?
- The effects of accelerator type on processability and mechanical properties of 60/40 NR/EPDM were investigated 12 and found that TBBS could be a proper choice for vulcanizing NR/EPDM blend as it provides not only the best scorch safety, but also the highest state of cure.
- What type of accelerator is used in vulcanization?
- Primary accelerator: this group of accelerators usually have a long burning time and are quickly cooked in the main stage of vulcanization Polymer accelerators are used to produce various types of rubber such as isoprene, styrene, butadiene and NBR. Sulfonamides are one of the most popular primary accelerators.
- Are vulcanization accelerators used as reclaiming/devulcanization agents?
- Vulcanization accelerators are applied as reclaiming/devulcanization agents, as they have effect on the process of breakdown of cross-links and on secondary vulcanization of resulting reclaimed rubber [16, 17].
- Do vulcanizing systems affect mechanical properties of reclaimed rubber?
- Rattanasom et al. investigated the effect of vulcanizing systems on mechanical properties of natural rubber (NR) vulcanizates containing 10–50 phr of reclaimed rubber. At this research two types of curing systems were used: conventional (CV) and effective (EV).
