Polymer Characterization

Our polymer characterization services can help you to better understand your products and materials.  We can help you to optimize your product applications, maintain quality control and unlock new uses through our approaches to characterizing polymers.  Different polymeric structures can have an influence on your processing performance and the physical behaviors of your products.

At Lucideon we can characterize polymers by molecular weight, weight distributions, branching and more.

Some of the techniques we use for polymer characterization are:

  • Fourier Transform Infrared Spectroscopy (FTIR) with Attenuated Total Reflectance (ATR) and microscope attachments – identify the generic type of polymers and additives in polymers.
  • Gel Permeation Chromatography (GPC) – determine the molecular weight and molecular weight distribution of polymers within the detectable range of molecular weights from a few thousand to hundreds of thousands of Dalton.
  • X-ray Diffraction (XRD) – quantitative appraisal of crystallinity, crystallite size and changes in crystalline phases of polymers; potentially identify semi-crystalline polymers based on their crystalline structures.
  • Differential Scanning Calorimetry (DSC) – determine glass / melt transition temperatures, sub-generic type, crystallinity and the thermal and processing history of polymer materials.
  • Thermogravimetric Analysis (TGA) – provide information about the decomposition temperature of polymers.
  • Melt Flow Index (MFI) Apparatus – evaluate the rheological performance and processability and enable quick assessment of changes to the molecular weight and structure of polymers.
  • Wet Chemistry – assess chemical resistance, solubility in solvents, liquid absorbability, etc.
