    GPE 3000 Glycerol-Initiated EO/PO Polyether CAS 9082-00-2

    GPE 3000, a glycerol-initiated EO/PO polyether (CAS 9082-00-2), is supplied for industrial formulation work. Grade selection for process fluids, surfactant systems or polyol formulations is based on hydroxyl number, viscosity, water content and EO/PO composition. Send your application, quantity and destination for a quotation; an existing specification helps match the grade to your requirements.

    • CAS: 9082-00-2

    Parameters

    CAS Number9082-00-2
    ECHA List No.618-655-1 (technical list identifier, not an EINECS number).
    Identity / CompositionGlycerol-initiated EO/PO polyether; variable chain lengths and EO/PO composition. No single fixed molecular formula.
    Grade / SpecificationIndustrial grades are selected by nominal average molecular mass, hydroxyl number, EO/PO composition, water content and viscosity with its test temperature and method.
    Key quality dataHydroxyl number, reported in mg KOH/g, measures hydroxyl-group content and supports formulation stoichiometry; it is not a purity percentage. Water content is commonly measured by Karl Fischer titration and reported with its units and result basis. Viscosity data state whether the result is dynamic (mPa·s) or kinematic (mm²/s), together with the test temperature and method; different types or temperatures are not directly interchangeable.
    PackagingPackaging type and net weight are specified in the quotation for the selected grade, quantity and destination.

    Grade characterization

    When molecular-mass distribution matters for grade matching, we can provide suitable SEC/GPC data with the reported averages and calibration basis. Polymerized EO content can be analysed using an applicable NMR method. For glycerol-initiated triols, some ¹H NMR methods include initiator signals in the reported EO value; the method and reporting basis therefore matter. Polymerized EO content alone does not establish chain sequence, residual monomer content or overall purity.

    Applications

    GPE 3000 is used in metalworking fluids, textile processing aids, emulsifier formulations and foam-control blends. Grade, concentration and operating temperature affect lubrication, dispersion and foam behaviour. For polyurethane formulations, hydroxyl number, hydroxyl functionality, terminal hydroxyl character where relevant, and water content affect grade selection. An industrial surfactant grade is not automatically a qualified polyurethane polyol.

    For related formulation options, compare the butanol-initiated EO/PO polyether BPE-1500 and the polypropylene glycol diol PPG-2000. Their initiator, monomer composition or nominal hydroxyl functionality differ from GPE 3000; they are comparison options, not direct one-for-one substitutes.

    The EO-only glycerol ethoxylate G-18 / Glycereth-18 and the linear PE 6800-type EO/PO/EO block copolymer offer further formulation comparisons. Compare their composition and chain architecture for the intended system rather than treating a shared polyether description as proof of interchangeability.

    Storage

    Keep GPE 3000 in tightly closed, compatible containers and protect it from moisture and contamination. Limiting exposure to humid air helps preserve the specified water content. The supplied grade TDS and SDS describe its storage and handling conditions.

    Documents and quotation

    We can provide a Certificate of Analysis (COA), Technical Data Sheet (TDS), Safety Data Sheet (SDS) and relevant grade qualification data, including test methods and reporting conditions. These documents support incoming inspection, safe handling and shipment planning. An existing specification helps match the quoted grade; share any destination-market document requirements with your enquiry.

    FAQ - Technical & Supply Chain

    • Q:

      Does GPE 3000 mean one fixed EO/PO composition?

      A: No. CAS 9082-00-2 identifies the glycerol-initiated EO/PO polyether family, while 3000 is a nominal average grade designation. Neither fixes a single EO/PO ratio, chain sequence or complete specification. Grade selection depends on the relevant hydroxyl number, water, viscosity, composition and test conditions.
    • Q:

      Can GPE 3000 be replaced by another polyether with a similar nominal molecular mass?

      A: Not on nominal molecular mass alone. Glycerol-initiated polyethers, butanol-initiated polyethers, PPG diols and linear EO/PO block copolymers can differ in composition, chain architecture and hydroxyl functionality. Compare the agreed grade data and evaluate the candidate in the intended formulation or process before replacement.
    • Q:

      Which quality data and documents are available for GPE 3000 procurement?

      A: We can provide COA, TDS and SDS with the applicable grade limits, test methods and reporting conditions. Key data include hydroxyl number in mg KOH/g, water content with its result basis, and viscosity type, units and test temperature. Suitable SEC/GPC distribution data and EO-content analysis can be provided when relevant to grade matching.
