PEG Polyethylene glycol Properties

Overview of PEG Polyethylene Glycol

PEG Polyethylene glycol with lower relative molecular weight (PEG200~600) has solubilization, solubilization, moisture retention, heat carrier performance. Relatively high molecular weight is commonly used as matrix, play a role in regulating viscosity, melting point, stability system.PEG Polyethylene glycol is an addition polymer with water. Those with a molecular weight below 700 are colorless, odorless, non-volatile, viscous liquids at 20°C, and are slightly hygroscopic. Those with molecular weights between 700 and 900 are semi-solid. Those with a molecular weight of 1,000 and above are light white waxy solids or flake-like paraffin wax or fluid powder. Miscible in water, soluble in many organic solvents, such as alcohols, ketones, chloroform, glycerides and aromatic hydrocarbons; insoluble in most aliphatic hydrocarbons and ether. As the molecular weight increases, its water solubility, vapor pressure, water absorption and solubility in organic solvents decrease accordingly, while the freezing point, relative density, flash point and viscosity increase accordingly.

Product Performance of PEG Polyethylene Glycol

Oxidized polyethylene has high chemical stability and can resist corrosion by oxygen, acid, alkali and other chemical substances.
Oxidized polyethylene is a solid, colorless or yellowish powder or granule commonly used in coatings, adhesives and plastic additives.
Flame retardancy: Oxidized polyethylene has good flame retardant properties and can effectively reduce the occurrence of fire accidents.

Application of PEG Polyethylene Glycol

PEG Polyethylene glycol is a colorless viscous liquid or white solid.Soluble in water and many organic solvents, easily soluble in aromatic hydrocarbons, and slightly soluble in aliphatic hydrocarbons.Certain metal salts are soluble in PEG Polyethylene glycol at approximately 100°C and remain stable at room temperature. These metal salts include calcium, cobalt, copper, iron, magnesium, manganese, tin and zinc chlorides, potassium iodide and ethyl mercury. It can be used as plasticizer, softener, wetting agent, lubricant, solvent, adhesive, and can also be used to prepare spices and pharmaceutical preparations.

Coatings and adhesives: PEG Polyethylene glycol can be used to prepare coatings and adhesives with good heat resistance and weather resistance, and is commonly used in automotive coatings, ship coatings and other fields.

Rubber and plastic additives: PEG Polyethylene glycol, as an important additive, is often used to improve the thermal stability and anti-aging properties of plastics and rubber.
Textile treatment agent: PEG Polyethylene glycol can be used in the twisting, processing and refining of textiles to improve the softness and washability of textiles.
