Litigation Support Services

Dr. John Spevacek is a polymers and plastics expert with 25 years professional experience. He is available to provide support in all aspects of litigation, such as
  • Technical consultation
  • Preparation for deposing other expert witnesses
  • Expert witness reports
  • Testifying as an expert witness

Trying to list all areas of my expertise is impossible. Even something as simple as studying an adhesive requires knowledge of both substrates being adhere together, the adhesive container, the intended use and exposure conditions, the actual use and exposure conditions, etc. So to say that I have experience with "acrylate adhesives" for instance, is to miss all the other technical issues that go well beyond the acrylate adhesive per se. With that said, here are:

Some of my Areas of Expertise
  • Polymers (plastics and rubber), including their chemistry, physics and characterization
  • Polymer material selection and their fitness for use
  • Polymer processing, especially extrusion and injection molding
  • Adhesives and adhesion, including medical grade adhesives
  • Weathering of polymers
  • Artificial/accelerated aging of polymers
  • Superhydrophobic surfaces
  • Rheological testing
  • Biocomposite materials

Some of the industries to which I have made contributions
  • Adhesives
  • Automotive
  • Coatings
  • Floor cleaning
  • Floor coatings
  • Food packaging
  • Food safety
  • Geomembranes and Plastic Netting
  • Medical Devices (both implanted and non-implanted)
  • Mining
