PLURONIC PE 6100

PLURONIC PE 6100 helps industrial formulations stay clean and controlled by limiting foam before it disrupts mixing, spraying, or circulation.
PLURONIC PE 6100's polymeric EO-PO structure gives the product a balanced character, combining surface activity with foam suppression in the same material.
PLURONIC PE 6100 is useful when a formulation needs quiet efficiency, meaning less foam, smoother flow, better handling, and more stable process performance.

PLURONIC PE 6100 is a low-foaming block copolymer for a wide variety of applications.

PLURONIC PE 6100 is a low-foaming nonionic surfactant based on a PO-EO block copolymer structure.
PLURONIC PE 6100 is designed for formulations that need foam suppression, wetting support, and stable processing performance.

PLURONIC PE 6100's polymeric structure helps control unwanted foam while still providing surface-active behavior in industrial and cleaning systems.
PLURONIC PE 6100 is especially useful in applications where excessive foam can disturb mixing, spraying, rinsing, circulation, or process efficiency. BASF describes PLURONIC PE 6100 as a low-foaming block copolymer for a wide variety of applications.

Applications of PLURONIC PE 6100:
PLURONIC PE 6100 is used as a low-foaming nonionic surfactant in formulations where foam suppression and process control are important.
PLURONIC PE 6100 is suitable for detergents, industrial cleaners, institutional cleaners, rinse systems, and hard-surface cleaning formulations.

PLURONIC PE 6100 can be used as a defoamer, antifoam agent, wetting aid, and foam-control additive in systems where excessive foam can disturb mixing, spraying, circulation, or rinsing.
PLURONIC PE 6100 is also useful in industrial processes, agrochemical formulations, metalworking fluids, and technical formulations that need low foam, surface activity, and stable liquid handling.

PLURONIC PE 6100 as a low-foaming block copolymer, and product range data lists it under low-foaming nonionic surfactants.
PLURONIC PE 6100 can be employed in situations in which foam is a nuisance, such as in domestic dishwashers and industrial bottle-washing machines.

PLURONIC PE 6100 suppress foam very well, even in the presence of protein, starch or size.
PLURONIC PE 6100 can also be used to defoam metal cleaning baths, acid dye baths and boiler feed water.

The polyethylene glycol content and the molar mass of the central polypropylene glycol block of surfactants of this type can be varied within wide limits, and the result is that they are exceptionally versatile.
The PLURONIC PE types can be tailored to boost their wetting, dispersing or emulsifying properties as the situation requires.

PLURONIC PE 6100 can be used to reduce foam or eliminate it altogether, and they can be used as solubilizers and thickeners.
Their ability to act as impregnating agents, humectants, plasticizers and lubricants can be exploited in a variety of situations.

PLURONIC PE 6100 can be used to adjust the viscosity of other liquids, to make tacky substances more coherent, and to disperse suspended solids.
PLURONIC PE 6100 can also be employed as heat transfer fluids and hydraulic fluids in some applications.

The PLURONIC PE types can be used in detergents and cleaners – in the dairy, brewery and soft drinks sectors, for instance –, in cleaners that are sprayed onto metal components to remove shavings and swarf, in the rubber and plastics industries, and in other branches of industry.

Foaming:
The PLURONIC PE types do not foam or, at most, they are very low-foaming.
The amount of foam formed decreases in line with their polyethylene glycol content.

PLURONIC PE types that contain less than 20% polyethylene glycol can be employed as antifoams.
PLURONIC PE 6100 is difficult to predict the foaming behaviour of surfactants in advance with standard test methods because of the influence of the type of soil and machinery, different temperature settings and the effects of the other ingredients in the formulation.

The results obtained by the beater method described in DIN 53902, Part 1, or the Ross-Miles method described in DIN 53902, Part 2 or ASTM D 1175-53 have to be substantiated by comparing them with results obtained by methods that correspond more closely to real conditions.
An effective method is to measure the level of foam produced in a dishwasher, because this closely corresponds to the conditions encountered in practice.

The rotating spray arm is slowed down by foam: the higher the rate of revolution, the less foam is present.
Foam formation can be encouraged by adding protein.

Chemical Nature of PLURONIC PE 6100:
PLURONIC PE 6100 is a 100% active, low-foaming, nonionic surfactant.
PLURONIC PE 6100 is block copolymers in which the central polypropylene glycol group is flanked by two polyethylene glycol groups.

The PLURONIC PE types are low-foaming, nonionic surfactants.
They are block copolymers in which the central polypropylene glycol group is flanked by two polyethylene glycol groups.

Nomenclature of PLURONIC PE 6100:
The PLURONIC PE types are designated by a four-figure or five-figure code.
The first digit – or first two digits – is a guide to the molar mass of the hydrophobe, in this case polypropylene glycol, on a scale of 1–10.
The second or third digit is the percentage of polyethylene glycol in the molecule, divided by ten.

Properties of PLURONIC PE 6100:
The consistency of the individual products in the PLURONIC PE range is determined by their polyethylene glycol content and the molar mass of the central polypropylene glycol block.
They tend to become more solid as these figures increase.
PLURONIC PE 6800 is supplied in the form of fine, free-flowing, non-tacky beads for ease of processing.

Solubility of PLURONIC PE 6100:
PLURONIC PE 6100 is a general rule that the solubility of PLURONIC PE types in water increases in step with the proportion of polyethylene glycol that they contain.
If two products contain the same mass fraction of polyethylene glycol, the molar mass of the polypropylene glycol block is the determining factor, and the one with the lower molar mass will be the more soluble.

For instance, PLURONIC PE 6800 is more soluble in water than PLURONIC PE 6100, which is less soluble than PLURONIC PE 3100.
All of the PLURONIC PE types are more soluble in cold water than in hot water.

As in all alkoxylates, the oxygen atoms in the ether groups form hydrogen bonds with water.
The molecules gradually dissociate as the solution warms up.

PLURONIC PE 6100 is for this reason that alkoxylates have a cloud point at which they form a separate phase.
Each product in the PLURONIC PE range has its own characteristic cloud point.

Wetting:
The most effective wetting agents contain a low proportion of polyethylene glycol, and their central polypropylene glycol block has a high molar mass.
The best wetting agents in the range are PLURONIC PE 8100, PE 9200 and PE 10100.

Compatibility:
The PLURONIC PE types are nonionic and therefore miscible with anionic, cationic and other nonionic surfactants.
PLURONIC PE 6100 do not react with cations such as Ca2+ or Mg2+, which means that they can be used in hard water.

They are also compatible with soluble polyanionic substances such as our Sokalan® CP types, Sokalan® PA types and carboxymethyl cellulose.
PLURONIC PE types are completely resistant to non-oxidizing acids at the concentrations at which they are normally used in applications, but while they are resistant to alkalis, they are not equally resistant.

Processing:
PLURONIC PE 6100 is advisable to stir the surfactant into water when preparing aqueous solutions, because solutions made up in the reverse order can have a very high viscosity.
Products with a high molar mass also form gels in water at certain concentrations.
