Urushiol-derived non-silane coupling agent ScienceDirect
Urushiol is an oily mixture of catechol derivatives with a 15-carbon tail at the 3-position with various degrees of unsaturation. The percentage of each species in the urushiol used in this work is determined by 1 H NMR integration as shown Fig. 1.The average degree of unsaturation is 1.82, i.e., 1.82C=C bonds per urushiol molecule.
Reversion of natural rubber is dependent on the nature of the curing system, choice of accelerator, and the temperature and time of cure. Conventional cure systems which contain a high ratio of sulfur to accelerator have higher moduli at optimum cure, faster rates of cure, but are more vulnerable to reversion.

Therefore, the rubber sheets were stored for 24 h before they were used for the next mixing stage. In the second stage, the cold compound was re-mixed in the internal mixer and the secondary accelerator DPG was added. The higher compound viscosity results in more effective dispersive mixing again.
- What is a rubber accelerator?
- Rubber accelerators are essential chemical compounds used in the vulcanization process of rubber, enhancing the speed and efficiency of this chemical reaction.
- What are the characteristics of DPG rubber?
- 2. Characteristics of DPG: - Acceleration: DPG functions as a medium-fast primary accelerator, meaning it promotes the vulcanization process in rubber production. - Moderate reactivity: It offers a balanced level of reactivity, making it suitable for a wide range of rubber types, including natural rubber (NR), synthetic rubber, and blends.
- What are the different types of rubber accelerators?
- Let’s explore some of the most commonly used types of rubber accelerators, including thiazoles, sulfenamides, and dithiocarbamates, and how they are employed in different applications. Thiazoles – Thiazoles are among the most popular classes of accelerators, particularly known for their moderate vulcanization speeds and excellent scorch safety.
- How do I choose the right rubber accelerator?
- Choosing the right rubber accelerator depends largely on the intended application and the desired properties of the rubber compound. Much like how thiazoles, sulfenamides, and dithiocarbamates offer specific advantages in performance and speed, Ample Worldwide ensures that its solutions are tailored to meet the precise needs of its clients.
- What is a dithiocarbamate accelerator?
- Dithiocarbamates – Dithiocarbamates are ultra-fast accelerators, known for their rapid vulcanization properties, even at lower temperatures. These are typically secondary accelerators used in combination with other types to increase vulcanization speed.
