vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. the chemical reaction between sulfur and the rubber hydrocarbon occurs mainly ac (doublet the c = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). the process takes around 6 hours at 140°C
vulcanization accelerator polymer stabilizer / alfa chemistry,a vulcanization accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. vulcanization accelerator also decreases the amount of sulfur needed to cross-link the polydiene, which improves the aging properties
rubber auxiliary agent dptt accelerator for rubber supplier
cas 120-54-7. chemical 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. chemical dptt is non-staining and is suitable for use in light colored vulcanizates. chemical dptt provides better processing safety and heat stability than other thiurams.

classification of accelerators rubber field info,the thiuram class comprises accelerators like tmtm, tmtd, tetd, tbztd, and dptt. thiurams are highly efficient accelerators used in the vulcanization of nr, sbr, br, nbr, and other highly unsaturated rubbers. they are particularly favored as primary accelerators for low-unsaturation rubbers like butyl (iir) and epdm, which undergo sulfur curing.
- 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 the function of mercapto sulphenamide in rubber vulcanization?
- It also functions as sulfur donor for vulcanization with low or no free sulfur. It causes very rapid and scorch-safe vulcanization of rubber along with good processing safety. It acts as activating secondary accelerator, when combine with other mercapto- or sulphenamide-type-accelerators.
- Is accelerator DPTT the same as akrochem?
- It is both, as all products of this type are a blend of the two forms. Akrochem DPTT may cause skin irritation in some individuals. Avoid prolonged or repeated contact with skin. Avoid breathing dust or vapor. Use with adequate ventilation. Accelerator DPTT is also available as Akroform® DPTT-70/EPR/P (pellets).
