Desiccant Masterbatch 

Price: Contact

Maxnerva Desiccant Masterbatch is a high-efficiency moisture-absorbing additive engineered to eliminate air bubbles, fish eyes, and surface defects caused by moisture in recycled or damp plastic resins. Formulated with active Calcium Oxide (CaO) and compatible carrier polymers, it absorbs internal moisture during high-temperature processing without disrupting production flows. Suitable for PE and PP applications, it improves product appearance and reduces scrap rates across blown film, injection molding, and extrusion manufacturing lines.

Key Benefits

  • Defect Prevention: Prevents surface imperfections, fish eyes, and voids in finished plastics.

  • Cost Efficiency: Reduces pre-drying requirements for recycled materials and lowers overall defect rates.

  • Process Continuity: Absorbs moisture dynamically during extrusion without slowing processing cycles.
