What is the purpose of desiccant masterbatch?
2026-08-17 08:20:49Desiccants masterbatches function in response to relative humidity (RH) within PE/PP plastic resins. They work by drawing/holding water molecules from the plastic inside the resins and chemically reacting with them so that the plastic product remains dry without defects and bubbles. Relative humidity is the percentage of water content in the resins vs. the maximum volume of moisture the desiccant masterbatch could eliminate by chemical method.
