these accelerators provide wide range of crosslink densities depending on type and dosage of accelerator used and exhibit flat reversion resistant cure. progressive increase in dosage of sulfenamide accelerator shows improvement in scorch delay, cure rate and state of cure.
classification of rubber vulcanizing accelerators based on,because the rubber vulcanizing accelerator has a great influence on the vulcanized rubber characteristics, it is necessary to classify and identify the three popular types of rubber vulcanizing accelerators to avoid using the wrong accelerator during tire production and to ensure the tire quality.
rubber accelerator etu with high quality
application: as the second accelerator, it has a little tendency to scorch, a high degree of processing safety and enables proper vulcanization to be attained speedily at normal vulcanizing temperatures. presents characteristics vulcanization kinetics and gives the vulcanization with excellent physical properties (high tensile strength, low

the accelerator which has been most widely used with metal oxide cures is ethylenethiourea (etu) or 2-mercaptoimidazoline. further extensive use of etu in the vulcanization of cr is somewhat in doubt since it is a suspected carcinogen.

- What is accelerator in rubber vulcanization?
- 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 vulcanization and thus improving 'aged' properties of the rubber vulcanizates.
- How does vulcanization affect use-related properties?
- Major effects of vulcanization [2-4] on use-related properties are illus- trated by the idealization of Fig. 2. It should be noted that static modulus increases with vulcanization to a greater extent than does the dynamic modulus.
- Do secondary accelerators increase vulcanization speed?
- The use of secondary accelerators increases the speed of vulcanization substantially but at the expense of scorch safety. The dosages of the secondary accelerators are generally between 10-40% of the primary accelerator. Accelerators some times are also be classified according to the chemical groups to which they belong.
- How do I select a vulcanizing accelerator?
- The selection of an accelerator will depend on the specific vulcanizing system and curing properties. Explore the classification of accelerators, the checklist to select the right accelerator based on the specific vulcanizing systems and curing properties.
