Additives are materials that are added to the primary resin to improve the polymer’s processability or its performance or appearance in some way. They are used with virtually all polymers either at the compounding stage or during processing, when they may be dosed in via a blender. Some categories of additives include flame/smoke retardants, impact modifiers, process aids, colorants and clarifiers.
