Polyethylene Glycol (PEG)
Polyethylene glycols are a family of linear polymers and are formed by an increased reaction of ethylene glycol with mono-ethylene glycol or ethylene glycol.
The general formula for the polyethylene glycol H (OCH2CH2) nOH is n is the average number of ethylene oxide groups. Different grades of polyethylene glycol are characterized by its molecular mass. For example, the PEG400 contains a distribution of polymers with a molecular weight of about 400, which is similar to an average of approximately 9 grams of repetitive ethylene oxide groups.
Depending on the average molecular mass, polyethylene glycols can be liquid or solid under standard conditions. Polyethylene glycol grades are 200,300,400,600,1000 in liquid form.
Polyethylene glycols are available in the range of 200 to 1000 molecules.
applications:
Cosmetic and toiletries
Polyethylene glycols Neutral, odorless, moisturizing, non-volatile compounds without causing irritation and irritation as a water-soluble, lubricant and softener in a wide range of cosmetic products - hygiene and personal hygiene products such as creams, lotions, Woods, pills, powders, and jellies are used.
Household detergent
Soaps, detergents, polishes, and cleaners are the main use of polyethylene glycols because these water-soluble products are inert and inert to low volatility and toxicity, as well as solvents or solvents.
Adhesives and textile
Polyethylene glycols are widely used in adhesive and textile industries as plasticizers, lubricants, softeners, anti-static and time-drying agents in adhesives.
In agriculture
As a soluble compound in water and solvent in organic insecticides, they can be assisted by suitable solvents for a variety of insecticides.
In color and cover
Polyethylene glycols are used intermediately in the preparation of alkyd resins and polyester to increase the spreading in water.
Ceramic Tile
Polyethylene glycols are widely used in ceramic and tile industries as a lubricant, lubricant, carrier, and connector. One of the most important tasks of polyethylene glycol is to use in the formulation of printing oils on the tile in different stages of baking, which allows printing well and without stirring on the tile surfaces.
Papermaking
Polyethylene glycols are used as a tool for increasing the flexibility and smoothness of paper, paper stabilizers, and paper softeners.
Transportation and maintenance:
Polyethylene glycol products have very low toxicity and are safe and suitable for hygienic cleaning products. When transporting products, wear safety glasses, PVC gloves, and anti-fogging. Polyethylene glycol products should be kept in a dry, covered area away from heat and sources of ignition. In case of contact with eyes, rinse eyes thoroughly for 15 minutes. See your doctor if you are eating.
Packing: Polyethylene Liquid glycols (200 to 1000) in 220-liter barrels (200 kg), each 4 barrels packed in a pallet.
Longevity: 24 months in the sheltered storage
The most important physical properties: Depending on the molecular mass, a wide range of physical properties, such as solubility, moisture absorption, vapor pressure, melting point and freezing and viscosity, are different.
