Polymers and Plastics

Because of their broad chemical and physical properties, plastics are among the most commonly used materials in the world.  The properties of a polymer are typically achieved by formulating specific polymeric macromolecules (matrix) with additives.  Generally, combinations of several additives are used to specifically tailor the properties of the plastic (e.g., color, stability, durability, surface reactivity, adhesion for coatings, etc.) to meet the needs of the end product.  A variety of analytical approaches and techniques are available to help customers solve issues in product development, process control, and failure analysis.  The following list summarizes analytical tasks which are regularly addressed with surface sensitive analytical methods:

 

  • Characterization of additives
  • Characterization of the monomer unit
  • Characterization of the end group
  • Determination of the average molecular weight
  • Segregation
  • Surface diffusion
  • Adhesive behavior
  • Surface topography
  • Monitoring of surface modifications
  • Blooming 
  • Particles
  • ...
