DESCRIPTION

Pluronic PE 10500 is an EO-PO-EO triblock copolymer with a central polypropylene oxide-rich block and terminal polyethylene oxide-rich blocks.
Pluronic PE 10500 contains hydroxyl groups at both ends of the average polymer chain.

Pluronic PE 10500 gains hydrophobic character from the polypropylene oxide block and hydrophilic character from the polyethylene oxide blocks.
Pluronic PE 10500 uses this amphiphilic architecture to concentrate at oil-water, solid-water, and air-water interfaces.

Pluronic PE 10500 contains approximately 50% polyethylene glycol or ethylene oxide-derived content by weight.
Pluronic PE 10500 contains a central polypropylene glycol block with a reported average molar mass of approximately 3,250 g/mol.

Pluronic PE 10500 has an average total molar mass of approximately 6,500 g/mol when calculated from the hydroxyl number.
Pluronic PE 10500 does not consist of molecules with one identical chain length because industrial block copolymers contain a distribution of polymer sizes.

Pluronic PE 10500 is represented by the general formula HO(C₂H₄O)x(C₃H₆O)y(C₂H₄O)zH.
Pluronic PE 10500 does not have one fixed stoichiometric molecular formula because the average block lengths can vary within the commercial specification.

Pluronic PE 10500 is manufactured by adding propylene oxide to a suitable initiator and subsequently adding ethylene oxide to both ends of the polypropylene glycol block.
Pluronic PE 10500 production requires controlled alkoxylation, catalyst management, purification, and adjustment to the required hydroxyl number.

Pluronic PE 10500 is supplied at approximately 100% active concentration as a white waxy solid.
Pluronic PE 10500 becomes easier to pump or mix after controlled warming above the melting range.

Pluronic PE 10500 has a reported melting point of approximately 44°C.
Pluronic PE 10500 should be heated only as much as necessary to obtain workable flow and prevent unnecessary thermal exposure.

Pluronic PE 10500 is more soluble in cold water than in hot water because hydration of the polyethylene oxide blocks decreases as temperature rises.
Pluronic PE 10500 can form micelles and eventually separate into a surfactant-rich phase as the solution approaches the cloud point.

Pluronic PE 10500 has a cloud point above 100°C in distilled water under EN 1890 Method A.
Pluronic PE 10500 has a reported cloud point of approximately 75°C in 5% sodium chloride solution under EN 1890 Method B.

Pluronic PE 10500 provides a surface tension of approximately 39 mN/m at 1 g/L and 23°C under the referenced test conditions.
Pluronic PE 10500 displays moderate rather than extremely rapid wetting, with a reported wetting time of approximately 300 seconds in the specified soda-ash test.

Pluronic PE 10500 is nonionic and therefore does not carry a permanent electrical charge in aqueous solution.
Pluronic PE 10500 is generally compatible with many anionic, cationic, and other nonionic surfactants.

Pluronic PE 10500 does not precipitate directly with calcium or magnesium ions in the manner of many ionic surfactants.
Pluronic PE 10500 can consequently be formulated in hard-water systems, although salts can still alter cloud point, solubility, and phase behavior.

HANDLING AND STORAGE

Handling: Handle Pluronic PE 10500 according to good industrial hygiene and chemical-processing practices. Avoid eye contact, prolonged skin contact, dust formation, aerosol generation, and unnecessary exposure to heated Pluronic PE 10500.
