Product Description

Desiccants, or as sometimes referred to moisture scavengers, are materials that will attract and chemically bind moisture. Desiccants can offer a simple and economical way to eliminate moisture problems in plastics processing that can otherwise cause unattractive surface defects such as lensing, voiding, and splash marks in the finished product.

Desiccant masterbatches can reduced the need for pre-drying of materials, allow processors to use recyclate with high moisture content and extend the control of processing moisture sensitive polymers.
