PPI has a long history of helping its clients in the pharmaceutical industry with respect to various problems related to medical devices/pharmaceutical packaging made out of polymeric materials. Such problems may include micro scale contamination of surfaces, surface reactions of plastic products with contained reagents, uneven distribution of various organic and/or metallic additives/catalysts in polymer matrix, anisotropy of mechanical properties of plastic parts with different orientation, molding defects, etc. PPI's capabilities and resources include, besides wet chemistry, Scanning Electron Microscopy (SEM)/ EDS (Energy Dispersive X-Ray Spectroscopy) including surface mapping, FTIR spectroscopy including fixed angle specular reflectance combined with a wide range of spectral libraries ( a dozen) containing several thousand spectra for unknown identification. PPI also can render help in materials selection and products design/processing for specific applications.
