PLURIOL E 9000's solid powder form provides an option for manufacturing processes requiring a particulate PEG ingredient.

Depending on the formulation, PLURIOL E 9000 can function as a binder to help hold components together.
PLURIOL E 9000 can also provide lubrication or support ingredient dispersion in suitable industrial applications.
These functions make it a versatile formulation ingredient, with performance depending on concentration, compatibility, and processing conditions.

PLURIOL E 9000 is a high-molecular-weight polyethylene glycol with an average molar mass of about 9000 g/mol.
PLURIOL E 9000 is supplied in powder form and belongs to the water-soluble PLURIOL E series of polyethylene glycols.

PLURIOL E 9000's solid PEG structure makes it useful in formulations that need binding, thickening, lubrication, dispersion support, humectancy, plasticizing, or consistency modification.
PLURIOL E 9000 is especially valuable when a formulation needs a stable, water-soluble polymeric ingredient that improves texture, processing behavior, and product uniformity.
PLURIOL E 9000 Powder as polyethylene glycol with approx. 9000 molar mass and approx. 65 °C melting point.

Uses of PLURIOL E 9000:
PLURIOL E 9000 can be used as a binder to support cohesion in solid formulations, as a lubricant to reduce friction during suitable processing operations, and as a dispersing agent to assist ingredient distribution in compatible systems.
PLURIOL E 9000 can also serve as a filler where a solid, water-soluble polyethylene glycol is required and may provide antistatic functionality in appropriate applications.
These uses reflect BASF’s stated functions for the Pluriol E range, with suitability depending on the formulation and processing conditions.

PLURIOL E 9000 is used as a thickener, binder, lubricant, dispersing agent, humectant, plasticizer, and consistency modifier in industrial formulations.
PLURIOL E 9000 is suitable for detergents, cleaners, coatings, adhesives, polishing compounds, textile auxiliaries, lubricants, and chemical intermediate production.

PLURIOL E 9000 can help improve product body, processing smoothness, dispersion stability, and uniform texture in water-based systems.
Because PLURIOL E 9000 is a high-molecular-weight polyethylene glycol powder, it is especially useful where a solid, water-soluble PEG is needed for controlled consistency, binding, and formulation stability.
PLURIOL E grades can be used as solubilizers, plasticizers, binders, humectants, lubricants, dispersing agents, mould-release agents, consistency modifiers, impregnation aids, and intermediates for polyesters and polyurethanes.

Binding Agent:
PLURIOL E 9000 can be used as a binder to help hold formulation components together and support the cohesion of solid products.

Lubricant:
PLURIOL E 9000 can provide lubrication during suitable industrial processing operations, helping reduce friction between contacting surfaces.

Dispersing Agent:
PLURIOL E 9000 can assist the distribution of ingredients within compatible formulations.

Filling Agent:
PLURIOL E 9000 can serve as a filler where a solid, water-soluble polyethylene glycol is required.

Antistatic Agent:
PLURIOL E 9000 may help reduce static buildup in applications compatible with polyethylene glycol.

Chemical Nature of PLURIOL E 9000:
The PLURIOL E types are polyethylene glycols that conform to the general formula HO(CH2CH2O)nH.
The degree of polymerization n determines the average molar mass of each product and the properties PLURIOL E 9000 displays.

Properties of PLURIOL E 9000:
PLURIOL E 200, E 300 and E 400 are clear, colorless liquids at 23 °C.
PLURIOL E 600 can have the consistency of a clear, colorless liquid, a milky white liquid or a semi-solid, depending on the ambient temperature.

PLURIOL E 9000 has a setting point of approx. 20 °C.
Polyethylene glycols with a molar mass of approx. 600 or more are solid at 23 °C.

They are supplied in the following forms.
E = Product supplied as cast solids in drums or in liquid form in heated road tankers.

Powder = White or slightly yellowish micronized granules with a particle size predominately in the 0.2 – 1 mm range.
Flakes =  White or slightly yellowish flakes with various particle sizes.

Solubility of PLURIOL E 9000:
All of the PLURIOL E types are easy to dissolve in water, and their solubility is not affected by water hardness.
Their solubility decreases to a certain extent as their molar mass increases.

They are resistant to moderately strong acids, alkalis and salt solutions.
Generally speaking, substances in this group are fairly inert, but they can react with vegetable and synthetic tanning agents and other substances that contain phenolic hydroxyl groups to form sparingly soluble addition products.

The PLURIOL E types with a low molar mass are soluble in alcohols, but their solubility decreases as their molar mass increases.
They are soluble in most aromatic solvents, but they are virtually insoluble in aliphatic hydrocarbons and petroleum fractions.

Stability of PLURIOL E 9000:
The PLURIOL E types are thermally stable in the absence of oxygen.

Compatibility of PLURIOL E 9000:
The PLURIOL E types are freely intermiscible, which enables homogeneous mixtures with specific properties to be prepared.
They are compatible with nonionic surfactants such as our Lutensol®, Plurafac® and Pluronic® types.

They are miscible to a greater or lesser extent with monomeric and polymeric substances of a largely hydrophilic nature – such as dyes and pigments, anionic and cationic surfactants, and animal, vegetable and synthetic glues and binders – and their compatibility is good.
The miscibility of the PLURIOL E types with fats, fatty acids, alcohols and oils, natural and synthetic ester and hydrocarbon waxes, petroleum fractions and other substances of a predominantly hydrophobic nature is limited.

Nevertheless, pseudomixtures or pasty dispersions can be made from some combinations of products by melting them into a vessel and allowing them to cool before stirring.
Solids, such as chromatic pigments, ceramic pigments, and abrasives in polishes and solid lubricants, can be ground into stable, homogeneous pastes with PLURIOL E types, providing that the solids are properly wetted, the viscosity is kept within reasonable limits, and the various ingredients are correctly proportioned.
