rubber additives dptt accelerator for rubber price
Dipentamethylene thiuramhexasulfide dptt is used as the primary or secondary accelerator in natural and synthetic elastomers and as a sulfur donor in low sulfur or sulfur-less cures. Dipentamethylene thiuramhexasulfide dptt is non-staining and is suitable for use in light colored vulcanizates.
joe walter considers how the tire curing and vulcanization,today cure package for tire compounds is composed of sulfur, an accelerator and an activator. sulfur, used at 3phr or less, remains the best cross-linking agent for nearly all tire rubber compounds whether natural or synthetic.
accelerator dptt for tyre and rubber product
dptt imparts unusually good heat resistance to sulfurless compounds and may be used as a primary accelerator for hypalon and butyl as well as an excellent secondary accelerator for epdm. it can also be used as a vulcanizing agent for heat resistant latex.

- What is accelerator DPTT?
- Accelerator DPTT is a non-discoloring and non-staining accelerator. It is a very active sulfur-bearing accelerator and contains approximately 25% available sulfur. DPTT imparts unusually good heat resistance to sulfurless compounds and may be used as a primary accelerator for Hypalon and Butyl as well as an excellent secondary accelerator for EPDM.
- What is DPTT used for?
- DPTT imparts unusually good heat resistance to sulfurless compounds and may be used as a primary accelerator for Hypalon and Butyl as well as an excellent secondary accelerator for EPDM. It can also be used as a vulcanizing agent for heat resistant latex.
- Which elastomers can be vulcanized?
- Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur. As a result, several of the same accelerators that are used with sulfur vulcanization systems can be used with zinc oxide/neoprene systems. Because there are so many, accelerators are generally classified by chemical family.
- 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.
