Optimization of Accelerator Mixing Ratio for EPDM Rubber
choice of the vulcanization accelerator, and the vulcanization characteristics vary widely depending on the type and mixing ratio of the accelerator [11]. Moreover, natural rubber and synthetic rubber
Once mixed, the rubber is discharged from the mixer and processed into slab rubber or pellets. Rubber mixing typically occurs in two or more stages wherein the rubber is returned to the mixer and re-mixed with additional chemicals. The initial stage results in non-productive compounds, and the final stage results in productive compounds.

Vulcanized Vegetable Oil (VVO) is used in robber compounds to improve ozone resistance, increase dimensional uniformity, reduce hardness and improve extrusion and calendering. VVO is an effective means to boost ozone resistance in NR applications that require non-staining and low bloom capabilities.

The new blends exhibited much better mechanical properties than the traditional ones. The results showed that glass spheres between 5 -13.5% in the new
- What vulcanization curve should a rubber accelerator have?
- Vulcanization Flatness: The accelerator should have a broad vulcanization flatness curve during the optimal vulcanization period. This is particularly important for thick and solid rubber products to ensure even vulcanization and prevent defects.
- What is vulcanization in rubber?
- Vulcanization is an essential step that enhances the physical and chemical properties of rubber, providing it with durability, elasticity, and strength. What are Rubber Accelerators?
- Increased Vulcanization Speed: Their main function is to accelerate the vulcanization process, allowing for more efficient production.
- Why do vulcanized rubbers need multiple accelerators?
- Accelerator Combination: Each accelerator has unique properties that affect the vulcanization process. The simultaneous use of multiple accelerators is often necessary to achieve the desired processability and excellent physical and chemical properties of the vulcanized rubber.
- What is a rubber accelerator?
- One of the key components in the manufacturing of rubber products is accelerators, which play a fundamental role in the vulcanization process. Vulcanization is an essential step that enhances the physical and chemical properties of rubber, providing it with durability, elasticity, and strength. What are Rubber Accelerators?
- Why should you choose a vulcanization accelerator?
- This results in a faster vulcanization reaction rate, shorter vulcanization times, lower reaction temperatures, and a reduction in the amount of vulcanizing agent required. When selecting a vulcanization accelerator, it's important to consider several factors to ensure optimal performance and quality of the rubber compound.
- Why is dispersibility important in rubber vulcanization?
- Dispersibility: The dispersibility of an accelerator in a rubber compound is crucial for efficient mixing and uniform vulcanization. Poorly dispersible accelerators increase mixing time and power consumption, leading to uneven vulcanization.
