Adipic Acid
C₆H₁₀O₄ · Hexanedioic Acid · 1,4-Butanedicarboxylic Acid
Adipic acid is a white, crystalline organic compound commonly used as an intermediate in the production of nylon and plasticizers. It is a moderately dense, free-flowing solid but can cake and compact under humid conditions. The material is slightly corrosive in moist environments and generates fine dust when handled in powder form. KWS designs enclosed, corrosion-resistant conveying systems that maintain consistent flow and control dust emissions.

| Dust Potential | High fine powder requires containment and filtration |
Handling Challenges
- Caking and bridging due to hygroscopic nature
- Corrosion in conveying components when exposed to moisture
- Dust generation and potential inhalation hazards
- Segregation or compaction during storage and transfer
- Need for controlled humidity to prevent product degradation
Summary
Adipic acid requires conveying and storage systems designed for crystalline, hygroscopic materials that can compact or cake under humid conditions. KWS Manufacturing provides engineered solutions—including screw conveyors, drag conveyors, and feeders—constructed with corrosion-resistant materials to ensure consistent flow, dust control, and product integrity.
With extensive experience handling chemical intermediates and crystalline powders, KWS ensures reliable, safe, and low-maintenance operation for adipic acid handling systems.
