    PRODUCT INFORMATION

    LEWATIT® ASB 1 P

    Lewatit® ASB 1 P is a premium grade, gel, strong base type I anion exchange resin specially suited for high
    purity separate or mixed bed applications if a reduction of the silica concentration is needed. The relatively
    open matrix of the polymer enables the user to more adequately treat waters of a higher content of organic
    molecules such as tannic and fulvic acids.

    Lewatit® ASB 1 P is produced on the basis of a cross-linked styrene divinylbenzene polymer. It is supplied
    in the form of spherical beads.

    Lewatit® ASB 1 P has high an exchange capacity combined with an excellent stability to organic fouling. It
    contains a minimum amount of fines (up to 50 mesh), resulting in low pressure losses.

    Lewatit® ASB 1 P is available in its chloride form.

    The special properties of this product can only be fully utilized if the technolgy and process used correspond
    to the current state-of-the-art and the operating conditions are adapted to the individual requirements.
    Further advice in this matter can be obtained from Lanxess, Business Unit Ion Exchange Resins.

    Additional Information & Regulations


    Safety precautions
    Strong oxidants, e.g. nitric acid, can cause violent reactions if they come into contact with ion exchange
    resins.
    Toxicity
    The safety data sheet must be observed. It contains additional data on product description, transport,
    storage, handling, safety and ecology.
    Disposal
    In the European Community Ion exchange resins have to be disposed, according to the European waste
    nomenclature which can be accessed on the internet-site of the European Union.
    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. No attempt should be made to accelerate the thawing process.
