Development of Compositional Analysis Procedures for Neoprene Formulations Used in Sonar Transducers

Abstract

A high-level decision was made by the Navy to procure fleet transducers using design specifications. Quality control of transducer elastomers by compositional analysis would be included as part of the specification. A research project was initiated to assemble a computer-control high-performance liquid-chromatography (HPLC) system and to develop the analytical procedures for measuring the organic additives, metal oxide, carbon-black content, and the molecular-weight distribution of the polychloroprene in uncured, compounded neoprene formulations. A brief discussion of HPLC is given to provide insight into the reasons for using this analytical technique. Detailed analytical procedures for measuring the levels of ingredients using the HPLC system are described. By using these procedures, acceptable levels of accuracy and precision have been achieved in measuring the concentration of ingredients in the neoprene formulations.
