Application Note: Moisture Determination of Different Plastic Granules

plastic moisture

Plastics are an important parameter in manufacturing and accurate measurement of plastics is essential for quality assurance. Moisture can impact the processability of the majority of plastics and if plastics are moulded or processed with moisture content which is out with the accepted range, then defects can occur, both structurally or visually.

In this application note, we determine the moisture of different plastic granulates using Precisa’s XM60/EM120 Halogen moisture analyser.
