PEG-8000 as non-ionic surfactant, a new choice for polymer additives, deeply cultivates the fine chemical market in multiple fields with its versatile performance
With the upgrading and upgrading of industries such as fine chemicals, textiles, rubber and plastics, and daily chemical products, the demand for high molecular weight polyethylene glycol series raw materials has steadily expanded. PEG-8000 (high molecular weight polyethylene glycol) has become the preferred additive for various formula upgrades in recent years, relying on its comprehensive advantages of high dispersion, strong lubrication, and excellent film-forming and moisturizing properties. Its application in the entire industry chain continues to expand, and compared with PEG6000, it has outstanding advantages in high temperature stability, dispersion, and anti caking. the company has a advantage on PEG-8000 product and higher quality of PEG supplier.
1、 Product physical and chemical properties, consolidating the underlying advantages of application
PEG-8000 is a high molecular weight non-ionic polyether synthesized by polymerization of ethylene oxide, with an average molecular weight range of 7000-9000. It appears as white particles or sheet-like solids at room temperature and has a melting point of 60-65 ℃; Easy to dissolve in hot water above 60 ℃ and alcohol solvents, slow to dissolve in cold water, insoluble in mineral oil and hydrocarbons; The pH of the aqueous solution is stable at 5.0-7.0, with excellent stability in weak acid, weak base, and hard water environments. It has a wide compatibility and can be compounded with non-ionic surfactants such as O-20 and O-25 to enhance efficiency. It has strong chemical inertness, low irritation, and is safe and environmentally friendly, meeting the entry standards for daily chemical and pharmaceutical grade raw materials. Compared to medium molecular weight PEG6000, the molecular chain is longer and the viscosity is higher, resulting in a comprehensive upgrade in film formation, dispersion, and lubrication performance.
2、 Five core functions empower formula optimization and upgrading
-Efficient dispersion and anti sinking:
-Rubber and plastic internal and external lubrication demolding:
-Dense film-forming water locking:
-Thickening suspension modification:
-Anti static and anti caking:
3、 Implemented across the entire industry, covering the five mainstream tracks
*Textile printing and dyeing industry
As a dispersant for dispersed dye grinding, anti sticking agent for printing paste, and anti-static agent for chemical fiber spinning, the dye bath is usually added with 0.2-0.8g/L, and the printing paste is added with 2% -4%; When used in combination with O-20/O-25, it balances even dyeing and dispersion, effectively improving the problem of high-temperature dyeing color spots and floating color rebound. It is commonly used for deep processing of tubular yarn and synthetic fabrics.
*Rubber and plastic processing
PVC、 General rubber granulation process with internal and external lubricants and filler dispersants, formulated with 0.3% -2.5% additives, optimized mixing process to reduce processing breakage and product defects, suitable for extrusion and injection molding multi process production.
*Daily chemical care&beauty
Toothpaste, skincare cream, and hair care product ingredients, with an added amount of 2% -10%, rely on moisturizing and thickening effects to shape the cream and improve skin texture; A compound of civilian laundry detergent and industrial cleaning agent, which enhances the dispersibility of dirt, is resistant to hard water, and leaves no residue during cleaning.
*Pharmaceutical and Feed Industry
Used in the pharmaceutical field as a tablet binder, suppository base, and sustained-release carrier to control the release rate of drugs; Anti caking additive for feed processing, optimizing particle forming effect, and improving feed storage stability.
*Coating papermaking and industrial cleaning
Water based coating color paste dispersing agent, adding 1% -3% to prevent coating precipitation; Paper making ink removal, pulp wetting, and blanket cleaning agents; Add 0.1% -0.8% to the industrial oil removal formula to synergistically remove oil stains, scale and disperse with surfactants from equipment.
At present, the global fine chemical industry is iterating towards environmentally friendly and highly stable formulations. The demand for non irritating and easily degradable polymer PEG raw materials is increasing year by year. PEG-8000, with its strong universality, is gradually replacing some traditional low efficiency dispersed lubricating agents. In the future, its market space in the fields of new energy coatings, high-end daily chemical products, and functional textile additives will continue to expand. The product is typically stored in sealed 25kg bags and stored in a cool warehouse with a shelf life of 24 months. It is easy to store and does not belong to hazardous chemicals.
