As the name suggests, a desiccant masterbatch is an advanced functional masterbatch developed to solve the moisture problem. A desiccant is a substance designed to eliminate humidity and enhance extrusion and injection processes. A desiccant masterbatch gives a complete solution to the processor so as to reduce or remove undesired moisture.
Moisture can be present in raw materials such as hygroscopic polymers, fillers, and pigments.
This masterbatch is used in eliminating moisture in virgin and recycled LD, LLDPE, HM, PP etc.
Desiccant masterbatch is suitable for blown film extrusion, injection molding, and blow molding process. It is used directly by mixing the masterbatch and the damp plastic material uniformly.
Characteristics
1. White Pigments :- Titanium dioxide (TiO2) is the most commonly used white pigment in masterbatches due to its excellent opacity and brightness.
2. Polymer Carrier :- The white pigments are incorporated into a polymer carrier, which can be a variety of plastics such as polyethylene (PE), polypropylene (PP). The choice of carrier polymer depends on the specific application and processing requirements.
3. Additives :- To enhance dispersion, stability, and processing characteristics, various additives like dispersing agents, processing aids, and stabilizers may be included in the masterbatch.
