Dessicant Masterbatch

Desiccant Masterbatch

Moisture is present in all polymers and can cause fisheye and surface defects in finished products, especially with technical resins. Desiccant masterbatch is added to the formula to absorb moisture from raw materials, reducing common processing issues (bubbles, fisheyes) and improving final product quality.

The main active ingredient is Calcium Oxide (CaO), a strong moisture absorber. It disperses well during processing, removes moisture, and prevents fisheye defects — effective in extrusion (blown film, cast film, blow molding) and injection molding. For recycled plastics, it also helps reduce moisture and limit oxidation during reprocessing.

Key Features

• Absorbs moisture to reduce bubbles and fisheyes
• High compatibility and dispersion
• Improves processing efficiency
