Guide for moisture and water content determination in plastic pellets

  • Free guide to determine moisture in plastics
  • Different testing methods covered

To assist those who work with plastics, both in the laboratory and along the production line, the company Mettler Toledo has launched a new guide on moisture and water content determination in plastics.

Moisture content of resins, such as polyamides or polycarbonates, is an important factor in plastic processing, appearance and properties of the final plastic product. Injection molding of too moist of plastic pellets results in processing problems and loss in quality of the final product. Typical symptoms of too much moisture are: splaying, formation of flash and impaired mechanical properties such as reduced impact and tensile strength.

The ‘Moisture Guide for Plastics’ presents the different methods of moisture and water content determination: Loss of weight, chemical reaction, thermogravimetric, spectroscopic and other types of analysis. The guide reviews the advantages and disadvantages of the respective methods, offers tips and tricks to enhance the reliability and performance of measurements and shows solutions to common challenges.
