Vulcanization & Accelerators Nocil
An 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. Accelerator also Decreases the Quantity of Sulphur necessary for vulcanizationand thus improving 'aged'
As the main universal acid accelerator, it is widely used in NR, IR, SBR, NBR, EPDM, IR and other synthetic rubber products. Its vulcanizates have good physical and mechanical properties. It has rapid vulcanization in natural rubber and sulfur-vulcanized synthetic rubber. Its critical temperature for vulcanization is low (125° C).

mercapto benzothiazole (MBT), which helps the vulcanized process and curing of the rubber; and Thiuram, which is a secondary accelerator that is used to give consistency to the mixture in the vulcanization and supports the MBT. Other used materials were sulphur, since being mixed with the raw rubber improve its hardness and
Rubber Chemicals An Overview
Accelerator also decreases the quantity of sulphur necessary for vulcanization thus improving 'aged' properties of the rubber compound. The pre-vulcanization inhibitor PVI(CTP) functions as vulcanization retarder which is a part of accelerator system . Products MBT, MBTS, CBS, MOR, TMT, TBBS (NS), DCBS, PVI fall under this category. Others
Rubber vulcanizing agent. Rubber scorch retarder. Rubber accelerator. Used for rubber products with high efficiency low poison and low solvent-extraction amount. Also can be customized. STORAGE VALIDITY: 1 year. Previous： MBT. Next

- Which accelerator is best for vulcanizates?
- A semi-ultra, multi-purpose accelerator with a long plated effect. Ot provides vulcanizates with good physical properties. In sulphur-free compounds, MBT acts as a scorch retarder, in CR compounds as a retarder. Dibenzothiazole disulfide A versatile semi-ultra accelerator with good processing safety.
- What is a vulcanizate accelerator?
- As a secondary accelerator blending with sulphonamides, thiazol, thiurams, and dithiocarbamates. The vulcanizates have excellent heat resistance and anti reversion performance. It is nitrosamine free, no blooming, no staining, no smell accelerator with very fast curing speed.
- Which is better vulcanizate or DPT?
- Suitable for the thick section rubber products, e.g. TBR, OTR and GOTR tires. DPT is better for sulfur cured NR and diene rubbers and particularly for EPDM. As a secondary accelerator blending with sulphonamides, thiazol, thiurams, and dithiocarbamates. The vulcanizates have excellent heat resistance and anti reversion performance.
