What types of additives are commonly used in rubber compounding?

The choice highlighting vulcanizing chemicals, fillers, and plasticizers as commonly used additives in rubber compounding is accurate, as these components play essential roles in ensuring the rubber's performance and characteristics.

Vulcanizing chemicals, such as sulfur, are critical for the process of vulcanization, which enhances the elasticity, resilience, and strength of rubber by forming cross-links between polymer chains. This transformation allows the rubber to withstand higher temperatures and improves its durability.

Fillers, including substances such as carbon black and silica, are incorporated to reduce costs, improve mechanical properties, and tailor the physical attributes of the rubber. They can enhance tensile strength and abrasion resistance while also affecting the material's processing characteristics.

Plasticizers are substances added to increase the flexibility and workability of rubber compounds. They lower the viscosity of the rubber during processing, which facilitates easier shaping and molding. By adjusting the plasticizer content, manufacturers can achieve the desired balance between stiffness and pliability in the final product.

Together, these additives enable manufacturers to optimize the performance of rubber for a variety of applications, making this selection correctly representative of the common practices in rubber compounding. Other options are too narrow or specific, as they do not cover the broad range of additives used in the industry
