ABSTRACT
A significant focus throughout this Handbook is that the identification, classification, and suitability of additives directly affect the cost and performance of end-use products. Included in these considerations are product quality, lot-to-lot reproducibility, production control, and product aging/weathering. A particular additive may be comprised of several components; however, only the major ingredient is identified in the description or MSD disclosures. Therefore, it is important also to know the composition and purity of the additives themselves. This is best achieved by developing and/or acquiring an inventory of well-defined standards.
