Moisture Detection Process
To test virtually any polymer for moisture, 80 grams of pellets are placed in a sample tube and inserted into the 360°F heater assembly.  Ambient air is pumped through a molecular sieve drying tube, and regulated by a metering valve and flowmeter before entering the heater assembly.  For 15 minutes the dried air transports the volatiles to a cellulose acetate absorber, located on the front of the MicroMoisture Instrument. The absorber is subjected to a microwave beam with the amount of moisture affecting the output of the microwave energy applied to the solid state electronics. State of the art microwave technology detects only the moisture in the absorber.

Splay and other defects in plastic products, caused by moisture in the hygroscopic plastic resins, has been the major cause of scrap in the polymer industry since its inception. Whether the time consuming problem is high regrind, over drying, low productivity, poor quality control or long start-ups, the costs to the plastic industry, and your company specifically, have been exceedingly high.
