Plastic Corrugated Structured Packing delivers exceptional corrosion resistance at lower costs than metal alternatives. Engineered from PP, PVC, PTFE, or PVDF polymers with specialized honeycomb designs, it provides high void ratios (>96%) and ultra-low pressure drops for acid scrubbing, VOC removal, and aggressive chemical processing up to 135°C.
Key Materials & Properties
| Polymer | Temp Range | Chemical Resistance | Key Applications |
|---|---|---|---|
| PP | ≤100°C | Acids, alkalis, solvents | Water treatment, cooling towers |
| PVC | ≤60°C | Chlorine, oxidants | Aquaculture, gas scrubbing |
| PVDF | 30-135°C | Halogens, fuming acids (ex. conc. H₂SO₄) | Pharma/food processing |
| PTFE/PFA | -200-260°C | All chemicals (except molten alkali) | Extreme corrosion environments |
Technical Advantages
• Critical Corrosion Resistance: Outperforms metals in halogen, acid, and alkali services
• Optimized Mass Transfer: Perforated surfaces increase liquid distribution & contact efficiency
• 95+% Void Fraction: Reduces pressure drop ≤50% vs. random packing
• Foam Suppression: Non-wetting surfaces minimize operational foaming
• Cost Efficiency: 30-70% savings over alloy metals with equivalent performance
