Measuring Moisture of Plastic Pellets

Moisture control is an important aspect for the production of high quality plastic parts. Measuring moisture content with the METTLER TOLEDO HX204 Halogen Moisture Analyzer is a practical and precise procedure.

Moisture content of many resins, such as polyamides or polycarbonates is an important factor for processing, product appearance and product properties. Injection molding of too moist plastic pellets results in processing problems and loss in quality of the final product.

Typical symptoms are well known: splaying, formation of flash as well as impaired mechanical properties such as reduced impact and tensile strength. Many plastics easily absorb moisture during transportation and storage. Therefore, the control of moisture content is crucial for the manufacturing of high quality products.
