    PPG 2000 (Polyether Polyol 220) CAS 25322-69-4

    PPG 2000, chemically known as Polypropylene Glycol or Polypropylene Oxide, is a polyether polyol specifically polymerized to an average molecular weight of 2000. This liquid polymer functions as a reactive soft segment intermediate, primarily reacting with isocyanates to create flexible linkages in polyurethane foam formulations, elastomers, and adhesives. It is typically applied in the production of flexible slabstock foams, reaction injection molding (RIM) systems, and industrial sealants. We ensure bulk supply with competitive factory pricing for industrial clients. Our inventory is managed to support customized specifications, and every shipment is accompanied by complete MSDS, TDS, COA documentation.

    Antifoaming agent for coatings, hydraulic oils, and heat transfer fluids.
    Defoaming agent in the processing of synthetic rubber and latex.
    Lubricants, plasticizers, mold release agents, and base materials for daily chemical products.

    Storage conditions

    Environment
    Storage temperature: Store at room temperature (18-25℃), avoid high temperatures (>35℃) or low temperatures (<-40℃) to prevent decomposition or solidification.
    Ventilation: Store in a dry, well-ventilated area, away from sources of fire, heat, and oxidizing substances (such as strong acids and alkalis).
    Light exposure: Avoid direct sunlight to prevent accelerated degradation caused by ultraviolet rays.
    Container requirements
    Store in the original sealed container, ensuring that the container is tightly closed to prevent the entry of air, moisture, or impurities.
    It is prohibited to use unlabeled containers to avoid confusion or misuse.
    Disposal of waste
    Empty containers may retain residual products and should be disposed of as hazardous waste. Reuse or random disposal is prohibited.
    Waste should be handed over to qualified disposal units in accordance with local environmental regulations.

    ‌‌Safety precautions

    Operation protection
    Personal protective equipment (PPE):
    Wear chemical-resistant gloves (such as nitrile rubber gloves), goggles, and protective clothing to prevent skin or eye contact.
    Emergency Management
    Skin contact: Immediately remove contaminated clothing and rinse with plenty of water for at least 15 minutes. Seek medical attention if necessary.
    Eye contact: Lift the eyelid and rinse with running clean water or saline for at least 15 minutes, and seek medical assistance.
    Inhalation: Quickly move to a place with fresh air and keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen and seek medical attention.
    Fire protection measures
    Fire extinguishing method: Use dry powder, carbon dioxide, or foam extinguishers. Direct water spray is prohibited (may cause spreading fire).
    Fire Risk: May decompose and generate toxic gases such as carbon monoxide and carbon dioxide at high temperatures. Wear a self-contained breathing apparatus.

    FAQ - Technical & Supply Chain

    • Q:

      Is CAS 25322-69-4 specific to PPG 2000?

      A: CAS 25322-69-4 is the general registry number for Polypropylene Glycol polymers of all chain lengths. "PPG 2000" refers specifically to the grade with an average molecular weight of 2000, which falls under this CAS registration but possesses specific viscosity and hydroxyl value specifications required for formulation.
    • Q:

      What is the primary role of PPG 2000 in polyurethane systems?

      A: It is intended for use as the polyol component in polyurethane synthesis. It reacts with diisocyanates to form the polymer backbone, providing flexibility and elasticity to the final industrial product, such as flexible foams or elastomers.
