Does GPE-3000 designate one fixed glycerol-initiated EO/PO polyether composition?

No. The CAS number and GPE-3000 designation cover a polyether family rather than one fixed composition. A commercial grade should be defined by its nominal molecular mass, EO/PO structure or ratio where relevant, functionality, hydroxyl value, water, viscosity and stated test methods. These controls are more informative than the designation alone.

Can a GPE-3000 source be substituted solely on a nominal molecular mass of 3000?

No. “3000” is a nominal average, not a complete technical specification. For a polyol system, compare the agreed hydroxyl value, functionality, water, viscosity and actual EO/PO architecture, then assess the candidate in the intended formulation or process. A similar nominal molecular mass does not establish equivalent processing behaviour.

Is a glycerol-initiated EO/PO polyether interchangeable with a linear EO/PO block copolymer?

Not automatically. A glycerol initiator gives a branched, nominally trifunctional polyether architecture, while linear EO/PO materials have a different chain arrangement and hydroxyl-group distribution. Even when EO and PO are both present, they should be compared by the agreed grade definition and evaluated in the intended system before replacement.

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

GPE 3000 is a commercial glycerol-initiated EO/PO polyether-triol distribution, not a single compound. Define the offered grade by average molecular weight, hydroxyl number, viscosity with test temperature, water and EO/PO composition on TDS/COA. Low-foam, wetting, dispersing or detergent performance is grade- and formulation-specific and must be retained only when supported by the actual TDS and application testing.

CAS: 9082-00-2
Synonyms: Polyoxyethylene polyoxypropylene glycerol ether; glycerol-initiated EO/PO polyether triol; GPE-3000
Einecs: 618-655-1
Molecular Formula: C₃H₅[O(C₃H₆O)x(C₂H₄O)yH]₃ — generic three-arm representation; variable EO/PO distribution, no single molecular formula.
Grade: Confirm the commercial grade code, average molecular mass or composition distribution, hydroxyl or viscosity data, water and physical form against the current TDS and COA.
Package: State required quantity, physical form and destination; confirm the current bag or container, liner, net weight, temperature handling and transport requirements before quotation.

Parameters

CAS Number	9082-00-2
EC / List No.	618-655-1
Identity / Formula	C₃H₅[O(C₃H₆O)x(C₂H₄O)yH]₃ — generic three-arm representation; variable EO/PO distribution, no single molecular formula.
Grade / Specification	Commercial polyether triol; specify average MW, hydroxyl number, water, viscosity, EO/PO composition and COA. Do not describe as a single pure compound.
Key physical data	Average MW, hydroxyl number, viscosity/test temperature, water and EO/PO composition are grade-specific. Confirm TDS/COA.
Packaging	Packaging depends on the selected grade and order. Confirm the current container, liner, net weight, compatibility and handling requirements before ordering.

Applications

Evaluate in compatible polyurethane/polyol, process-aid or surfactant formulations according to the actual grade. Treat low-foam, wetting, dispersion and detergent effects as test-dependent, not inherent universal claims.

For related industrial polyether raw materials, see BPE-1500 and PPG-2000.

Storage

Store in the original tightly closed compatible container in a cool, dry, ventilated area, away from heat, ignition sources, moisture and incompatible materials. Prevent contamination and follow the supplier SDS.

Safety / Regulatory

Use the current supplier SDS, workplace controls and buyer risk assessment. Confirm classification, transport status and destination requirements before handling or shipment.
