Using recycled raw materials is becoming increasingly important for both cost and sustainability. However, the moisture these materials carry can cause visible defects in production.
Where does moisture come from?
Moisture is a common problem in hygroscopic polymers, fillers, pigments, and especially recycled raw materials.
Signs of moisture in production
- Porosity in the polymer during production
- Voids in molded parts or extruded sheets
- Lensing and film bubble breaks in film applications
How does desiccant masterbatch work?
Desiccant masterbatch eliminates the moisture present during processing by chemically binding it. It is a non-toxic, eco-friendly additive with no adverse effect on the physical or chemical properties of plastic products.
No need for pre-drying means savings in both energy and time.
Benefits
- Use of higher proportions of recycled or moist raw materials
- The ability to use high filler loadings
- No need for pre-drying in many applications
- Less scrap, higher productivity, lower energy consumption
If odor is also a problem
Unwanted odors can also occur alongside moisture in recycled raw materials. In that case, odor neutralizer masterbatch gives the final product a cleaner odor profile.
We can measure the moisture content of your raw material in our laboratory and work with you to determine the right dosage rate for desiccant masterbatch.
