LEWATIT® MonoPlus SP 112 H

Summary

Product identification

• Product Name: Lewatit® MonoPlus SP 112 H
• Common Description: Strongly acidic, macroporous cation exchange resin with beads of uniform size (monodisperse) based on a styrene-divinylbenzene copolymer, in fully regenerated form (H⁺).
• Functional group: Sulfonic acid
• Matrix: Styrenic
• Structure: Macroporous
• Appearance: Beige, grey
• Delivery form: H⁺

Applications

• Demineralization of water for industrial steam generation (co-current or modern counter-current systems).
• Polishing in combination with Lewatit® MonoPlus MP 800 or Lewatit® MonoPlus MP 800 OH (Multistep System or mixed bed).
• Condensate polishing in combination with Lewatit® MonoPlus MP 800 or Lewatit® MonoPlus MP 800 OH.

Key Features

• High flow rates during regeneration and loading.
• Good utilization of total capacity.
• Low rinse water requirement.
• Homogeneous throughput of regenerants, water, and solutions.
• Virtually linear pressure drop gradient across the entire bed depth.
• Good separation of components in mixed bed applications.
• High chemical and osmotic stability.
• Particularly low pressure losses compared with standard resins due to high monodispersity and very low fines content.

Safety Precautions

• Strong oxidants, e.g., nitric acid, can cause violent reactions if they come into contact with ion exchange resins.
• Refer to the safety data sheet for additional information on product description, transport, storage, handling, safety, and ecology.

Disposal

• Ion exchange resins must be disposed of according to the European waste nomenclature within the European Community.

Storage

• Recommended storage: Above freezing point of water, under roof, in dry conditions, without direct sunlight.
• If frozen, allow to thaw gradually at ambient temperature before handling or use. Do not accelerate thawing.
• Packaging stability is limited to 24 months under recommended storage conditions. Check packaging condition regularly if used beyond this period.
