Performance & Applications
1. Polyethylene glycol series products are suitable for pharmaceuticals. Lower molecular weight polyethylene glycols can be used as solvents, cosolvents, o/w emulsifiers, and stabilizers, for the preparation of cement suspensions, emulsions, injectables, and more. They are also employed as bases for water-soluble soft gels and suppositories. Higher molecular weight solid wax-like polyethylene glycols are commonly used to increase the viscosity and solidifying properties of low molecular weight liquid PEGs, as well as to compensate for other drugs. For drugs that are not easily soluble in water, this product can serve as a carrier for solid dispersion agents to achieve solid dispersion objectives. PEG 4000 and PEG 6000 are excellent for coating materials, hydrophilic polishing materials, film materials, and capsule materials, plasticizers, lubricants, and as bases for droplets, used in the preparation of tablets, capsules, microcapsules, and more.
2. PEG4000 and PEG6000 serve as excipients in the pharmaceutical industry for the preparation of suppositories and ointments; as sizing agents in the paper industry to enhance the luster and smoothness of paper; and as additives in the rubber industry to improve the lubricity and plasticity of rubber products, reduce energy consumption during processing, and extend the service life of rubber products.
3. Polyethylene glycol series products can be used as raw materials for ester-type surfactants.
4. PEG-200 can serve as a medium for organic synthesis and a high-grade heat carrier. It is used as a moisturizer, inorganic salt solubilizer, and viscosity regulator in the daily chemical industry. In the textile industry, it acts as a softener and antistatic agent. It is also employed as a wetting agent in the papermaking and pesticide industries.
5. 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 the abrasive effect and improves the luster of metal surfaces.
6. PEG-1000 and PEG-1500 are used as matrices or lubricants and softeners in the pharmaceutical, textile, and cosmetics industries; as dispersants in the paint industry; and improve the water dispersibility and flexibility of resins, with a usage rate of 20~30%. They can enhance the solubility of dyes in inks, reduce volatility, and are particularly suitable for wax paper and stamp pad inks. They can also be used to adjust the viscosity of ballpoint pen inks. In the rubber industry, they act as dispersants, promoting the curing process and are used as dispersants for carbon black fillers.
7. PEG-2000 and PEG-3000 are used as molding agents in metal processing, lubricants for metal drawing, stamping, or shaping, cutting fluids, and for polishing, grinding, cooling, and welding agents; in the paper industry, they serve as lubricants and also as hot melt adhesives to enhance quick re-wetting capabilities.
8. PEG-4000 and PEG-6000 are used as matrices in pharmaceutical and cosmetic manufacturing for viscosity and melting point adjustment; as lubricants and coolants in the rubber and metal processing industries; as dispersants and emulsifiers in agrochemical and pigment production; and as anti-static agents and lubricants in the textile industry.
9. PEG8000 is used as a base material in the pharmaceutical and cosmetic industries for adjusting viscosity and melting point; as a lubricant and coolant in the rubber and metal processing industries; as a dispersant and emulsifier in the production of pesticides and pigments; and as an antistatic agent and lubricant in the textile industry.
