LEWATIT® S 8227 Mg

Summary

Product identification

Lewatit® S 8227 Mg is a food grade, macroporous, weakly acidic cation exchange resin based on a crosslinked polyacrylate. It is bead-shaped and has a special bead size distribution for use in household filter systems.

General Description:

• Ionic form as shipped: Na⁺/Mg²⁺
• Functional group: Carboxylic acid
• Matrix: Crosslinked polyacrylate
• Structure: Macroporous
• Appearance: White, opaque

The resin is partly charged with magnesium and sodium and is suitable for the decarbonisation and softening of drinking water in household filter systems.

Operating limits

• Stability at pH-range: 0 - 14
• Stability temperature range: -20 to +70 °C
• Storability of the product (max.): 1 year
• Storability temperature range: -20 to +40 °C

Specified Data

• Uniformity Coefficient: max. 1.8
• Bead size: > 90 % (0.4 - 1.6 mm)
• Effective size: 0.57 (+/- 0.05) mm
• Total capacity: min. 4.3 eq/l

Physical and Chemical Properties

• Bulk density (+/- 5 %): 800 g/l
• Density (approx.): 1.20 g/ml
• Water retention: 52 - 58 wt. %
• Volume change (operational swelling, typical): -30 % (Mg,Na > Ca)

Additional Information & Regulations

Safety precautions: Strong oxidants, e.g. nitric acid, can cause violent reactions if they come into contact with ion exchange resins. Observe the safety data sheet.

Storage: It is recommended to store ion exchange resins at temperatures above the freezing point of water under roof in dry conditions without exposure to direct sunlight. If resin should become frozen, it should not be mechanically handled and left to thaw out gradually at ambient temperature. It must be completely thawed before handling or use.

Disposal: In the European Community, ion exchange resins have to be disposed of according to the European waste nomenclature.
