- 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.
- Is ZnO a good activator for rubber vulcanization?
- Actually, CdO showed better activating behavior in rubber vulcanization [ 38 ], but its higher toxicity precludes its use for substituting ZnO. Therefore, at the moment, ZnO still remains the most efficient activator of rubber vulcanization.
- 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.
- Is rubber vulcanized by zinc complexes?
- Nevertheless, rubber was vulcanized by zinc complexes in the presence of the typical curing agents of a sulfur-based vulcanization process, including micro-crystalline ZnO (5 phr).
- Can zinc based activators improve vulcanization efficiency?
- Very recently, keeping a high vulcanization efficiency, innovative zinc-based activators for rubber vulcanization process have been proposed, based on the introduction of more active and dispersed zinc centers, in order to reduce the amount of ZnO and the zinc leaching.
- How to improve the efficiency of sulfur vulcanization reaction in rubber industry?
- Multiple requests from the same IP address are counted as one view. The efficiency of sulfur vulcanization reaction in rubber industry is generally improved thanks to the combined use of accelerators (as sulphenamides), activators (inorganic oxides), and co-activators (fatty acids).
