Dessicant Masterbatch

Dessicant Masterbatch

Polybatch desiccant masterbatches can counter problems which develop during the processing of plastics due to the presence of moisture. Moisture can be present in raw materials such as hygroscopic polymers, fillers and pigments. Reclaim and recycled polymer can also have a high moisture content. When processing polymer with a high moisture content the polymer can become porous and show voids in moulded articles or extruded sheet. In film applications the high moisture content can lead to lensing and film bubble breakage.

 

Polybatch desiccant masterbatch chemically binds moisture during processing and allows higher levels of reclaim or recycled polymer to be used; addition of higher filler levels; and can reduce the need for pre-drying in many applications. Polybatch desiccant offers a simple and cost effective solution to solve moisture problems.
