Plastic is a mainstay in our society as it is used in an infinite number of products and applications.  Plastics are formulated for their intended use.  Plastics may contain some water that is formed in high-temperature molding and the water bubbles can cause holes and other defects, impacting the mechanical properties, quality, and appearance of the plastic products. The way to avoid these issues is with the use of desiccants. Desiccants work to remove water during processing, effectively eliminating the presence of air bubbles and other defects.
