INTRODUCTION TO POLYMER ADDITIVES AND STABILIZATIONB obbijo van Beusichem, , Senior Staff Scientist, Expert Services, Michael A. Ruberto, , Head of Regulatory Services, NAFTA, Expert ServicesCiba Expert Services, Ciba Specialty ChemicalsPoster prepared preparation of purest POLYMER is simply not possible!Structural defects and impurities can not be excludedOrganic materials undergo degradation in the presence of peroxides, alcohols, ketones, aldehydes, acids, is assisted by: Energy ( mechanical stress, heat, light) metals / -ions (catalyst residual, impurities, co-add.)Oxidation can affect mechanical propertiesDiscoloration, rougher surface, decreased tensile strengthOxidation of hydrocarboncompounds proceeds autocatalyticallyPolymers are used in ALL aspects of our lives, including pharmaceutical packaging and medical device the use of the proper stabilization package, polymers will degrade.
