LEWATIT® A 8072 +
PDF datasheet mirror for LEWATIT® A 8072 + (Lanxess LEWATIT). Verify with OEM before design.
Summary
Product identification
Lewatit® A 8072+ is a heterodisperse, weakly basic anion exchange resin based on a gel-type acrylic-divinylbenzene matrix.
Common Description:
- Delivery form: free base
- Functional group: tertiary amine
- Matrix: acrylic
- Structure: gel
- Appearance: ivory, translucent
Operating limits
- Stability pH range: 0 - 14
- Operating temperature: max. 60 °C
- Max. pressure loss during operation: 150 kPa
Feed water
Lewatit® A 8072+ is suitable for demineralization of water for industrial steam generation, especially in systems with high organic fouling potential. It is also effective for removing organic matter, particularly from surface water.
Product water
This resin is particularly recommended for applications requiring low silica leakage, especially when combined with a strong dissociated anion exchange resin.
