For moisture-sensitive and high-performance materials, water exposure during processing can introduce unnecessary risk, from hydrolytic degradation to extended drying cycles and additive variability. PEAK offers waterless pelletizing for moisture sensitive applications, including antimicrobial compounds, biodegradable materials, high performance polymers and more. 

benefits of waterless pelletizing

• Eliminates Water Contact: Moisture-sensitive materials can absorb water during conventional pelletizing, requiring additional drying and risking hydrolytic degradation. Waterless systems prevent this exposure entirely.
  
  
• Preserves Material Integrity: Polymers such as biodegradable resins and certain high-performance materials are susceptible to molecular weight reduction when exposed to moisture and heat. Waterless pelletizing helps maintain polymer structure and performance properties.
  
  
• Reduces Post-Processing Requirements: Without water exposure, materials often require less drying time — improving efficiency and reducing energy consumption.
  
  
• Protects Additive Performance: Antimicrobials, specialty fillers, and functional additives can be sensitive to prolonged moisture or thermal cycling. Waterless processing helps maintain additive distribution and effectiveness.
  
  
• Cleaner Processing Environment: No water means reduced risk of contamination, wastewater handling, or filtration challenges — which can be especially important in medical and regulated applications.
  
  
• Improved Pellet Quality for Certain Formulations: Waterless systems can provide uniform pellet geometry while avoiding surface moisture or pellet clumping associated with some water-based methods.

waterless pelletizing applications

• Antimicrobial compounds
• Biodegradable and bio-based materials
• High-performance engineering polymers
• Hygroscopic resins
• Additive-sensitive formulations

when to Selecting Water-less pelletizing:

• The resin is highly hygroscopic
• The formulation is hydrolytically sensitive
• Additive integrity is critical
• The end-use application demands tight property control
• Additional drying steps would introduce risk or inefficiency

When performance, compliance, and consistency are non-negotiable, processing strategy matters just as much as formulation. If you're developing a moisture-sensitive compound and want to minimize risk from the start, let’s connect.
