cure mapping in rubber vulcanization: peroxide cures of epdm
abstract. “cure mapping” takes the complementary viscous and elastic outputs of cure rheometry and plots them against each other, so that the resultant plot is no longer in the time domain. such outputs are routinely available for rubber vulcanization, and in this paper we explore the cure maps for a series of peroxide cures on epdm. the cure map from moving die rheometer outputs is a plot.
supervision of ethylene propylene diene m-class (epdm) rubber.ethylene propylene diene monomer (epdm) rubber is widely used in a diverse type of applications, such as the automotive, industrial and construction sectors among others. due to its appealing features, the consumption of vulcanized epdm rubber is growing.

- How does EPDM vulcanize?
- EPDM requires more sulfur than what the stoichiometry of the few available double bonds dictates to obtain a proper degree of vulcanization; a mix of accelerators is added in amounts reaching the limits of solubility in such rubber. Adding even more causes “blooming,” the appearance of a white powder on the surface of the vulcanizate.
- Are peroxide cure maps available for rubber vulcanization?
- Such outputs are routinely available for rubber vulcanization, and in this paper we explore the cure maps for a series of peroxide cures on EPDM. The cure map from moving die rheometer outputs is a plot of viscous torque against elastic torque, and the variables explored herein include the levels of peroxide and coagent.
- How has vulcanization changed the rubber industry?
- Vulcanization revolutionized the rubber industry, enabling the production of high-performance rubber products with diverse applications. Some common examples of vulcanized rubber products include tires, gaskets, seals, conveyor belts, shoe soles, and various industrial and consumer goods.
- What is vulcanized rubber?
- A vulcanized rubber in this sense is a solid and will retain its shape and dimensions. Vulcanization is a very important process in the rubber industry and conducted at relatively high temperatures (140–200 °C).
- What vulcanization system is used for natural rubber?
- Both discovered the use of Sulfur and White Lead as a vulcanization system for Natural Rubber. This discovery was a major technological breakthrough for the advancement of the world economy. Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process.
- What are some examples of vulcanized rubber products?
- Some common examples of vulcanized rubber products include tires, gaskets, seals, conveyor belts, shoe soles, and various industrial and consumer goods. The vulcanization process can be tailored to achieve specific properties, depending on the type and amount of sulfur used, the temperature and time of heating, and the presence of other additives.
