Additives are among the most important products used in the chemical industry and, in particular, the polymer industry. They serve to enrich the desirable properties and minimize or eliminate objectionable characteristics in many polymers and plastics in use today. The development of new products is influenced substantially by both the selection and concentration of appropriate polymer additives. Each compound is identified by its chemical or trade name. All databases undergo the Sadtler Data Review Protocol to provide you with the highest standard available in spectral data today. These rigorous qualifying procedures start at data acquisition and continue throughout the database development process. All databases are tested in Sadtler laboratories by certified professionals with extensive training in spectroscopy and are validated by outside consultants. Every effort is made to maintain a high standard of accuracy before a spectrum can be placed in a collection. 1.) Purity checked by another spectral technique. 2.) Chemical and physical properties listed. 3.) Chemical composition defined. 4.) Chemical structure included. 5.) Sampling technique listed. 6.) Databases created specifically for searching. 1,480 Spectra; Sadtler Product Code: 4248
