Directory Guidance on Poly(Ethylene Oxide)
Product Introduction:
Poly(Ethylene Oxide), also known as Polyethylene Glycol (PEG), is a colorless, odorless, non-toxic waxy solid or viscous liquid. It is a non-ionic, water-soluble polymer with excellent lubricity, moisturization, and biocompatibility. Its molecular weight range is very wide, ranging from several hundred to tens of thousands, which determines its different physical states from liquid to solid.
Low molecular weight Poly(Ethylene Oxide) (such as PEG-400) is usually a transparent liquid, while high molecular weight Polyethylene Glycol (such as PEG-6000) is solid or in the form of solid particles. Its appearance is amorphous or crystalline, with good water solubility, soluble in water and many organic solvents.
The main characteristics of Poly(Ethylene Oxide) include hydrophilicity, good biocompatibility, low toxicity, and good lubricity. It has good solubility in water, but as its molecular weight increases, its solubility and fluidity gradually decrease. Polyethylene Glycol has strong chemical stability, acid and alkali resistance, and can maintain stability over a wide temperature range.
In addition, Poly(Ethylene Oxide) also has good adjustability. By changing the degree of polymerization, its physical properties such as molecular weight, viscosity, melting point, etc. can be adjusted. This makes Polyethylene Glycol widely used in fields such as pharmaceuticals, cosmetics, food, and industry. Depending on the molecular weight, PEG can also exhibit different functions. For example, low molecular weight PEG can be used as a solvent, lubricant, or drug carrier, while high molecular weight PEG can be used for emulsification, thickening, and other purposes.
Due to the non-polar nature of Poly(Ethylene Oxide), it is compatible with various organic solvents, including alcohols and ketones. At the same time, it has good stability to heat and light, and is not easily oxidized or hydrolyzed, which makes it very useful in a wide range of industrial applications, especially in environments that require heat resistance and chemical corrosion resistance.

What Are The Uses of Poly(Ethylene Oxide)
Product service:
Poly(Ethylene Oxide) (PEG) has diverse uses in pharmaceuticals, cosmetics, industrial applications, chemical industry, and other special applications due to its unique physical and chemical properties.
In the field of medicine, Poly(Ethylene Oxide) is used as a pharmaceutical excipient, which significantly improves the release rate and stability of drugs as a base for drop pills, ointment bases, and as a component of tablets and film coatings.
In addition, Poly(Ethylene Oxide) technology improves the pharmacokinetic and pharmacodynamic properties of drugs, prolongs their half-life, reduces immunogenicity, and enhances their water solubility and stability.
In the field of medical devices, the application of Poly(Ethylene Oxide) hydrogel in surgery, such as wound adhesion, hemostasis, etc., shows its excellent biocompatibility and low toxicity.
In the field of cosmetics and personal care products, Poly(Ethylene Oxide) is mainly used as a moisturizer and solvent. Its good water solubility and moisturizing properties enable it to form a protective film on the skin surface, reduce water evaporation, and increase skin moisture and softness.
Poly(Ethylene Oxide)’s low viscosity and excellent solubility make it an ideal solvent and lubricant in oil-free toners and shampoos.
In industrial applications, Poly(Ethylene Oxide) is widely used as a lubricant and coolant in the metal processing and textile industries due to its excellent lubricity and thermal stability.
In the field of metal processing, the use of Poly(Ethylene Oxide) can reduce friction between tools and workpieces, lower processing temperatures, improve processing accuracy and surface smoothness.
In the textile industry, Poly(Ethylene Oxide) serves as a spinning aid, sizing agent component, and solvent and dispersant for dyeing operations, improving the quality and production efficiency of textiles.
In the chemical industry, Poly(Ethylene Oxide) serves as a dispersant and carrier solvent, and its high solubility and surface activity enable it to effectively reduce the mutual attraction between solid particles, forming a uniform dispersion system.
In the paint industry, coatings with added Poly(Ethylene Oxide) exhibit better anti settling performance and glossiness.
In the pharmaceutical industry, Poly(Ethylene Oxide) can be used as a drug carrier to enhance drug solubility, stability, and improve drug release characteristics. PEGylation technology is commonly used in the preparation of anticancer drugs, antibiotics, etc.
In addition, Poly(Ethylene Oxide) has also demonstrated its unique value in other special applications. As a phase transfer catalyst, Poly (Ethylene Oxide) promotes more rapid and complete heterogeneous organic reactions in the field of organic synthesis.
In the preparation of superabsorbent resin, Poly(Ethylene Oxide) based superabsorbent resin has been widely used in the fields of personal hygiene products, agriculture, medical treatment and environmental protection due to its water absorption and gel strength.
In the food industry, Poly(Ethylene Oxide) is used as an additive to increase the moisture retention and extend the shelf life of food. In addition, PEG also plays a role in anti adhesion and anti caking in food packaging.
In summary, the multifunctionality and adaptability of Poly(Ethylene Oxide) make it irreplaceable in various industries, with broad application prospects. With the advancement of technology and the continuous development of new applications, the use of Poly (Ethylene Oxide) will further expand.
