epdm rubber solutions echo supply echo engineering
epdm is typically vulcanized with sulfur; however, vulcanization can also occur using peroxides when sulfur-free rubber is required. additionally, different additives or materials can be used during epdm manufacturing to provide the desired physical properties; for example, food-grade epdm can be produced using fda-approved ingredients for food processing operations.

crosslinking of polymers: rubber vulcanization springerlink
vulcanization resides in the reaction of elemental sulphur, organic sulphur compounds or organic peroxides with linear polymer chains, when crosslinks are forming. the most important and at the same time the oldest vulcanizing agent of polydiene rubbers is sulphur. polymers can also construct crosslinks by peroxides.
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.
vulcanization of epdm rubber compounds with and without blowing agents
vulcanization of industrial-like ethylene propylene diene termonomer rubber compound is studied using a differential scanning calorimetry (dsc). the analysis starts with dsc information to obtain the total transformation heat, followed by an isothermal-dynamic temperature ramp that captures diffusion-controlled reaction kinetics.

- 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 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.
- 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).
- Is vulcanized rubber reprocessible?
- Vulcanization is a slow, irreversible process, which takes place on heating, leading to a thermoset structure. Vulcanized rubbers cannot be softened or melted and are therefore not reprocessible. TPE polymers however are generated by a transition from melt to solid, which is rapid, reversible and takes place on cooling.
- What is a thermoplastic vulcanizate?
- Thermoplastic Vulcanizates, or TPVs, are part of the thermoplastic elastomer family of polymers, primarily composed of polypropylene and EPDM rubber. The EPDM rubber within the polypropylene matrix is vulcanized, which provides good compression set resistance.
- 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.
