As significant improvements are made to thermoplastic materials from the first generation of monomodal pipe compounds to the current generation of high melt strength, bimodal pipe compounds, signihnt innovations have occurred to assure quality pipe compounds are produced and used in this industry. One of these innovations is the means in which material suppliers have utilized technological improvements to assure consistent incorporation of the additive components in the pipe compound. The presence of these additive components in the compound is critical to the processing of the compound into pipe or fittings and subsequently, to the performance characteristics of the final product. These additive components may contain antioxidants, acid neutralizers, ultraviolet stabilizers, hindered amine light (HALS) stabilizers, processing aids, or color pigments. Individually, these chemical compounds may present safety, health, and environmental challenges in the consistent incorporation of the additives during the production of the pipe compound. However, the use of additive blends (commonly called compressed additive blends or Superblend&) in a physical form that is conducive for safe handling and feeding provides the material supplier an excellent means to produce quality pipe compounds. This paper/presentation introduces the participants to the various types of additive blends utilized in the thermo~lasticindustrv and orovides ~ i case ~ studv e examples on piping systems that were manufactured frorh kmpounds ;sing the additive blend technology. Key Words Additive blends, additive types, antioxidants, color pigments, UV absorbers, light stabilizers
