Product performance and characteristics of PEG-10000
With the continuous upgrading of water-based coatings, high-end rubber and plastic, and fine daily chemical industry formulas towards high stability and high dispersion requirements, ultra-high molecular weight polyethylene glycol PEG10000, with its ultra long molecular chain structure, has become a high-end functional additive that distinguishes PEG8000 from small and medium molecular weight PEG series. Its advantages in powder anti agglomeration, film formation protection, and long-term lubrication are highlighted.
1、 Product physical and chemical characteristics
PEG10000 is a polymer polyether produced by polymerizing ethylene oxide, with an average molecular weight range of 9500-11000. It appears as white crystalline particles at room temperature and has a melting point of 62-67 ℃. It is a high melting point specification in the PEG solid category; The product is soluble in hot water above 80 ℃, and swells slowly in cold water at room temperature. It is insoluble in oil and hydrocarbon organic solvents. The pH of the aqueous solution is maintained at 5.0-7.0, and its chemical properties are stable in weakly acidic, weakly alkaline, and high hardness water environments,
2、 Core advantages and features of the product
*Super strong powder coating dispersion force
Ultra long polymer chains can wrap inorganic fillers, pigments, and dye particles in all directions, firmly locking in small powders, blocking particle adsorption and agglomeration, and effectively inhibiting sedimentation and layering of pigments and filler suspensions. It is suitable for high solid content grinding systems.
*Dense film-forming barrier protection
The surface of the material can quickly form a continuous hydrophilic film, with outstanding water locking and moisturizing ability. It can not only prevent the product from drying and cracking, but also isolate dust adhesion in the air, achieving a dual effect of dust prevention and moisture retention.
*Long term external lubrication and demolding performance
In rubber and plastic processing, there is a focus on external lubrication effects, forming a lubrication isolation layer at the contact surface between the raw materials and the mold, reducing the probability of molten materials adhering to the mold, minimizing demolding damage and mold sticking defects. Compared with low molecular weight PEG, it has stronger high-temperature resistance and lubrication continuity.
*Excellent anti-static and anti caking properties
By relying on hydrophilic thin films on the surface to export static electricity from chemical fibers and powders, we can alleviate the problems of fiber static electricity and chemical powder storage agglomeration from the root, greatly improving the storage stability of granular materials.
*Low migration, long-lasting stability
The high molecular weight makes it difficult to migrate and precipitate, and it is less prone to volatilization and loss in long-term formulations and high-temperature processing conditions. The stability of the finished product in the later stage is better than that of PEG6000 and PEG8000.
3、 Mainstream industry implementation and application
*Textile printing and dyeing: high-end dispersed dyes, sand grinding dispersants, anti sticking agents for printing pastes, and anti-static agents for ultrafine fibers, mostly used in the production of high value-added chemical fiber fabrics;
*Rubber processing: High end PVC, engineering plastic granulation external lubricant, filler dispersing agent, improve extrusion molding smoothness;
*Daily chemical and pharmaceutical: High end solid detergent and pharmaceutical sustained-release formulation raw materials, used as sustained-release carriers and paste shaping aids;
*Coatings and feed: high concentration water-based color paste dispersant, particle feed specific anti caking agent.
4. Market Summary
PEG10000 is positioned as a high-end polymer lubricant dispersion raw material, and PEG4000/6000 is preferred for conventional general formulas. For products with strict requirements for dispersion, film formation, and anti caking, PEG10000 is the preferred alternative solution, and the demand in the downstream high-end fine chemical industry is steadily increasing year by year.
