Additives for PVC


PVC is a uniquely versatile resin with end uses from rigid window profiles to potable water pipe. This versatility is due to the use of a wide range of organic and inorganic additives. This presentation will introduce the essential additives including thermal stabilizers and lubricants as well as the non-essential additives including impact modifiers, process aids, and inorganic fillers for rigid PVC applications. An overview of each class of additives will be covered as well as selection criteria for each.
