Additives To Finished Polymer :

Product of the polymerization process is unchangeable PVC. Before PVC can be made into finished products, it constantly needs conversion into a compound by the incorporation of additives such as heat stabilizers, UV stabilizers, lubricants, plasticizers, processing aids, impact and thermal modifiers, fillers, flame retardants, biocides, blowing agents and smoke suppressors, and, optionally pigments.

The choice of additives use for the PVC finished product is controlled by the cost performance requirements of the end use specification e.g. underground pipe, window frames, intravenous tubing & flooring all have different kind elements to suit their performance desires.
