What is Plasticization?
Plasticization of a rubber compound refers to the process of adding plasticizers to the rubber to improve its flexibility, workability, and other properties. A plasticizer is a chemical compound that is added to a material to make it more pliable and easier to shape.

In the case of rubber, plasticizers are added to improve its processing characteristics such as reducing the viscosity of the rubber compound, making it easier to mix, extrude, or mold. This can also improve the physical properties of the rubber, such as its elongation, tensile strength, and tear resistance.

However, excessive plasticization can also lead to negative effects such as decreased hardness, increased swelling and reduced durability. The selection and amount of plasticizer added to a rubber compound must be carefully considered to achieve the desired properties of the final product.
