ASTM Testing: MPI offers a wide range of American Society for Testing and Materials (ASTM) standardized testing methods to meet your needs. Not sure which test is appropriate for your material or process? MPI can assist with the proper selection of tests methods and sample configurations.

Analytical Testing: Compositional analysis, analysis of unknown materials or raw material contaminants and identification of products are among the analytical testing services available at Mississippi Polymer Institute.  We also offer a chemistry wet lab capable of reactions, titrations, and extractions.

MPI’s analytical capabilities encompass a broad spectrum of testing. We have a multitude of in-house capabilities as well as access to equipment at The University of Southern Mississippi’s School of Polymers and High Performance Materials. Utilizing methods such as Nuclear Magnetic Resonance (NMR), Fourier Transform Infrared (FTIR) and Electron Microscopy, MPI assist with your analytical testing needs. We can analyze your material to determine properties, composition, changes and much more. We also have experience with testing to improve processes and to explain material properties.

Physical and Mechanical Testing: MPI’s expertise and equipment can cover a multitude of testing scenarios related to physical and mechanical properties -- from thermal properties, tensile strength and impact resistance to flexural property determination and melt flow rate.

Utilizing state-of-the-art instrumentation such as Instron mechanical testing machines, Differential Scanning Calorimeters (DSC) and Thermogravimetric Analyzers (TGA), MPI can test your product’s physical properties over a range of temperatures.

MPI can create standard test samples, condition samples in accordance with standard test methods and provide detailed and explanatory reports once results are obtained.

Custom Testing: MPI is uniquely able to accommodate non-routine test requests and will perform custom testing specific to your individual needs. This includes in-house tests created by and for specific companies or modified versions of standardized test methods.

MPI will work to obtain or fabricate specific test equipment or fixtures for our clients when needed. This equipment will remain in our laboratory for your sole use, as needed.

Please contact us if you are looking for a particular method that is not included in our detailed list. New methods and capabilities are frequently being added.
