The desiccant masterbatch reacts chemically with moisture during melt processing, binding with it irreversibly and becoming a part of the polymer. It remains stable to processing temperatures when added to polymers. Surface defects caused by moisture, such as lensing and fisheyes in films, bubble breakage, voids, pinholes, silver streaks in moulded articles, can be reduced through moisture removal. The moisture is responsible for affecting the surface appearance as well as mechanical properties of final products like impact strength, tensile strength, elongation and compressive strength because of porosity created by moisture in final articles. Several sources of moisture can contribute to polymer processes including fillers, pigments, and additives, washed and sorted recycled polymer streams, wet polymers, and materials stored in high humidity areas. Decreased preheating time and energy savings can be achieved by integrating Desiccant Masterbatch.
