Additives are used to modify and improve the characteristics of polymers to suit specific uses as illustrated in the following passage. These additives are chosen deliberately so as to control properties like flexibility, durability, and processability. Examples are Chlorinated Paraffin Wax, Dibutyl Phthalate, Dioctyl Phthalate, and Epoxy soy oil used mainly for extending and softening PVC plastics. These additives enhance the flexibility, flame retardance, and processability of PVC formulations to attain quality products for various applications.
