The importance of accurately measuring the moisture content of plastic resin in the molding process of medical devices

One important variable to monitor and control for during the production of plastic medical device parts is moisture content. Resin manufacturers provide material specification sheets detailing the maximum moisture specification, or the maximum allowable ratio of water in the resin before molding or extrusion. Depending on the resin, maximum moisture specification can vary from 0.20% to as low as 0.005% moisture.
