Desiccant masterbatches can counter problems which develop during the processing of plastics due to the presence of moisture and prevents adsorption of moisture during transportation. Moisture can be present in raw materials such as hygroscopic polymers, fillers and pigments. Reprocess polymer can also have high moisture content. When processing polymer with high moisture content the polymer can become porous and show voids/lower tensile in the final articles or extruded/blown sheet. In film applications the high moisture content can lead to film bubble breakage.
Desiccant masterbatch chemically binds moisture during processing and allows higher levels of reprocess polymers & fillers to be used.
Desiccant Masterbatches are based on extra pure Calcium Oxide minerals. These masterbatches are used in eliminating moisture in virgin and recycled LD, LLDPE, HM, PP, etc. These are mainly used in blown film, moulding & pipe.
CaO Desiccant Masterbatches help to reduce:
Windows/lenses in films;
Silver streak in molding.
Increases filler addition level
Increases Reprocess polymer addition level
