zdec rubber accelerator: characteristics, applications
zdec is an organic compound belonging to the dithiocarbamate class of accelerators. it is a white to light yellow powder with a faint odor. chemically, it consists of a zinc atom attached to two ethyl groups and a dithiocarbamate functional group. zdec is known for its excellent solubility in rubber and compatibility with various types of

high-performance sulfur insoluble lanxess
nitrosamine-generating sulfur donors can be replaced by non-toxic caprolactam disulfide (cld, sulfur donor) or dithio-phosphates (e.g. sdt, sulfur donor plus accelerator) in all common sulfur-curable rubbers using standard, semi-ev (eficient vulcanization) and ev curing systems. all common primary and secondary accelerators, activators and
compounding and vulcanization springerlink,sulphur vulcanizates provide an outstanding balance of cost and performance, exhibiting excellent strength, flexibility and durability at very low cost. one major limitation imposed upon the use of sulphur as a vulcanizing agent is that the elastomer must contain some chemical unsaturation [ 11 ].

although zdec is described as the most potent accelerator among the group, it remains as an important accelerator because of its excellent performance in accelerating and enhancing the crosslink
zdec masterbatch (dithiocarbamate accelerator harwick,properties. mixland zdec masterbatch is a fast curing accelerator for nr, sbr, nbr, ir, iir, biir, epdm. it exceeds zdmc in accelerating effects and shows a slight tendency to premature vulcanization. it is also used as a secondary accelerator for all sulfur curable elastomers. in general mechanical rubber goods, it is used with tbbs.
accelerator systems factory supplier,accelerators and accelerator systems part i covered the meaning of vulcaniza-tion with respect to rheology, selection of accelerators, polymer accelerator interaction and the primary accelerators. the focus here will be on two types of ultra/secondary accelerators, the dithiocarbamates and thiurams and their role in rubber curing systems.
- Is ZDEC a good rubber accelerator?
- ZDEC is a versatile rubber accelerator with notable characteristics, including ultra-fast acceleration, high reactivity, good scorch safety, and excellent vulcanization properties. It finds widespread application in various rubber products, including tires, industrial rubber goods, footwear, and wire and cable insulation.
- What are zinc-complexes in natural rubber latex sulphur vulcanisation systems?
- Zinc-complexes are essential ingredients in natural rubber latex (NRL) sulphur vulcanisation systems as they enhance the vulcanisation efficiency and improve the vulcanisate properties. Sulphur, zinc-type accelerators and zinc oxide (ZnO) are the main chemical ingredients utilised in a vulcanisation system.
- How effective is PTDC in a dry natural rubber?
- In this context PTDC was evaluated for its effectiveness at 60, 80 and 100 ̊C in a dry natural rubber and compared with piperidinium cyclopentamethylene dithiocarbamate (PPD) and ZDBC-extra/ZIX and ZDEC. PPD and ZDBC-extra/ZIX are considered to be very effective in low temperature curing.
- Which accelerators are compatible with vulcanizates?
- All common primary and secondary accelerators, activators and retarders are compatible. Standard sulfur system: >1 phr sulfur/insoluble sulfur, usually without sulfur donor. Additionally 0.2–1.0 phr sulfur donor to improve the physical properties of the vulcanizates
