Desiccant Masterbatch
A desiccant masterbatch that chemically binds moisture during processing and eliminates the need for pre-drying in most applications.
A simple, effective, and economical solution to moisture-related problems.
Desiccant masterbatch is a non-toxic, eco-friendly additive that has no adverse effect on the physical or chemical properties of plastic products. It offers a simple, effective, and cost-efficient solution to moisture-related problems encountered during plastics processing.
Desiccant masterbatch eliminates the moisture present during processing by binding it chemically. This makes it possible to use higher proportions of recycled or moist raw materials. It also allows high filler loadings and, by eliminating the need for pre-drying in many applications, saves energy and time.
Used in molding processes, desiccant masterbatches strongly absorb the moisture contained in plastic raw materials and additives. This contributes to higher product quality, lower scrap rates, greater productivity, and reduced energy consumption.
What problems does moisture cause?
Moisture is a common problem in hygroscopic polymers, fillers, pigments, and especially recycled raw materials.
-
Porosity
High moisture content can cause polymers to become porous during production.
-
Voids
Voids can form in molded parts or extruded sheets.
-
Lensing and bubbles
In film applications, it can lead to lensing and film bubble breaks.
Application areas
- HDPE, LDPE, and PP blown film; high-quality bags
- Recycled products
- Injection-molded products
Key advantages
- Cost reduction
- Improves surface gloss
- Increases strength
