afte-processing secondary accelerator. can be used as primary in latex. high resistance to hydrolysis, low solubility in rubbers. fast at higher vulcanization temperatures. it has longest anti-scorching capability in the dithiocarbamates. recognized to have low nitrosamine potential. used in sheeting, extrusions and latex, nr, iir, sbr, and epdm.
anti- reversion agent,antiscorching agent,rubber accelerator,the vulcanization of rubber is mainly carried out with sulfur, but the reaction between sulfur and rubber is very slow, so vulcanization accelerators appear. 07-19 2019
factory supply Rubber Addtives Rubber Accelerator Zdec
zbec (zinc dibenzyl dithiocarbamate) is a primary accelerator for natural and synthetic rubber. its chemical formula is c30h28n2s4zn. it functions by forming a complex with the sulfur and rubber polymer, which cross-links the polymer chains. this cross-linking process is what gives the rubber its elasticity and strength.
vulcanization agent - an overview sciencedirect topics,vulcanizing the rubber with mostly used vulcanizing agent sulfur initiates the cross-linking of rubber that is not saturated [26]. however, sulfur, as a vulcanizing agent, does not proceed swiftly. when rubber and hydrocarbons make chemical reactions, this process generally involves double bonds or c c, along with it every cross-linking needs 40–55 atoms of sulfur without accelerator.

- What is zbec accelerator?
- ZBEC is an ultrafast dithiocarbamates accelerator which no produce nitrosamine and a primary or secondary accelerator for natural and synthetic rubber such as EPDM, IR, SBR, NBR, IIR, etc. Compared to traditional dithio- carbamates accelerators, ZBEC has higher processing safety.
- What is the tensile strength of vulcanizate accelerated by zbec?
- Vulcanizate accelerated by ZBEC has tensile strength is similar with other dithiocarbamates when dosage is same. For EPDM: 0.8-2.5phr; For NR, SBR, NBR: 0.8-2.0phr. Net weight 25kg/PE bags lined carton; Net weight 600 kg/pallet.
- What is qureacc zbec?
- 0.50 Max. QUREACC®ZBEC is a very fast primary or secondary accelerator for natural and synthetic rubber. It is non-staining, non discoloring and is safer processing than ZDBC. It is also useful as a secondary accelerator for the continuous vulcanization of butyl rubber extrusions. ZBEC has found usefulness in minimizing harmful nitrosoamines.
- What is Mixland+ zbec used for?
- In association with HTS or VULTAC®, Mixland+® ZBEC improves antireversant effect. It has a high solubility in rubbers. Carpet backings, foam rubber, rubber threads, rubberised textiles, bathing caps, bath mats, footwear, cable coverings and wire insulation, etc...
- Does zbec activate thiazoles or sulfenamides?
- It can activate thiazoles or sulfenamides and can be activated by alkaline accelerators. Vulcanizate accelerated by ZBEC has tensile strength is similar with other dithiocarbamates when dosage is same.
- Does zbec reduce harmful nitrosoamines?
- ZBEC has found usefulness in minimizing harmful nitrosoamines. Nitrosodibenzylamine is not carcinogenic, according to publish literature.
