METTLER TOLEDO
The METTLER TOLEDO Plastics Moisture Determination Guide brings information on the most important methods for determining moisture and water in plastics, such as weight loss, 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 improve the reliability and performance of measurements, and shows solutions to common challenges.
The moisture content of resins, such as polyamides or polycarbonates, is an important factor in the processing, appearance and properties of the final product of the plastic. Injection molding with too much moisture from granules in processing generates results with problems and loss in quality. Typical symptoms of excess moisture are: widening, flash formation and poor mechanical properties, such as reduced impact and tensile strength.
Therefore, the control of moisture content is crucial for the manufacture of high-quality products.
