Desiccant Concentrates—are designed to bind moisture during the processing of plastic materials. The active ingredient in these masterbatches can react chemically with water molecules and effectively remove them from the system. Desiccant masterbatches may be effective for products produced with hygroscopic materials where lensing (fish eyes) can be a problem. Moisture absorbing masterbatches often find applicability where lensing can be a problem after storage of raw materials in high humidity areas. Concentrates containing a desiccant can theoretically bind up to about 20% of the masterbatch weight; in practice, the binding ability will be lower.
Common Ampacet desiccant masterbatches include 50-70% water scavenging compound in PE or PP.
