Continuous moisture monitoring helps plastics processors prevent material degradation, optimise dryer performance, and stabilise product quality during bulk material handling.
Impact of Moisture on Resin Processing In plastics processing, controlling moisture is critical to maintaining product quality and operational efficiency. Polymer resins, particularly hygroscopic types such as polyamide, PET, polycarbonate, and PLA, absorb atmospheric moisture. When heated during processing, excessive moisture causes hydrolysis, breaking polymer chains and weakening mechanical strength. This can result in brittleness, surface streaking, voids, and elevated scrap rates. Moisture Variations Across Material Handling Moisture levels fluctuate at multiple stages during material ha
