Characteristics and Applications

PEG-200	PEG-200 serves as a medium for organic synthesis and a high-demand heat carrier. In daily chemical industries, it functions as a moisturizer, an inorganic salt solubilizer, and a viscosity modifier. In the textile industry, it acts as a softener and anti-static agent, while in the papermaking and pesticide industries, it serves as a wetting agent.
PEG-400 PEG-600 PEG-800	PEG-400, PEG-600, and PEG-800 are used as matrices in pharmaceuticals and cosmetics, as well as lubricants and wetting agents in the rubber and textile industries. PEG-600, when added to electrolytes in the metal industry, enhances polishing effects and increases the gloss of metal surfaces.
PEG-1000 PEG-1500	PEG-1000 and PEG-1500 are used as matrices or lubricants and softeners in pharmaceuticals, textiles, and cosmetics industries. In the coatings industry, they serve as dispersants, improving the resin's water dispersibility and flexibility, typically used at concentrations of 10-30%. They also enhance dye solubility and reduce volatility in inks, particularly suitable for wax paper and printing inks, and can adjust ink viscosity in ballpoint pen inks. In the rubber industry, they act as dispersants, promoting vulcanization and serving as dispersants for carbon black fillers.
PEG-2000 PEG-3000	PEG-2000 and PEG-3000 are used as mold release agents in metal processing, lubricants for metal drawing, stamping, or forming, cutting fluids, grinding coolants, polishing agents, and welding agents. In the papermaking industry, they serve as lubricants and hot melt adhesives, enhancing rapid rewetting capabilities.
PEG-4000 PEG-6000 PEG-8000	PEG-4000, PEG-6000, and PEG-8000 are used as matrices in pharmaceutical and cosmetic production, adjusting viscosity and melting points. In rubber and metal processing industries, they serve as lubricants and coolants, and in pesticide and pigment production, they act as dispersants and emulsifiers. In the textile industry, they function as anti-static agents and lubricants.
