Performance & Applications
1. Polyethylene glycol (PEG) series products are suitable for pharmaceutical applications. Lower molecular weight PEGs can be used as solvents, cosolvents, o/w emulsifiers, and stabilizers, for making cement suspensions, emulsions, injectables, etc. They also serve as matrices for water-soluble soft gels and suppositories. Higher molecular weight solid waxy PEGs are commonly used to enhance 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 act as a carrier for solid dispersion agents to achieve solid dispersion goals. PEG 4000 and PEG 6000 are excellent coating materials, hydrophilic polishing materials, film materials and capsules, plasticizers, lubricants, and matrix for droplets, used in the preparation of tablets, capsules, microcapsules, and more.
2. PEG4000 and PEG6000 are used as excipients in the pharmaceutical industry for the preparation of suppositories and ointments; as coating agents in the papermaking 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 power consumption during processing, and prolong the service life of rubber products.
3. Polyethylene glycol series products can serve as raw materials for ester-type surfactants.
4. PEG-200 serves as a medium for organic synthesis and a high-grade thermal carrier, used as a moisturizer, inorganic salt solubilizer, and viscosity regulator in the daily chemical industry; as a softener and antistatic agent in the textile industry; and 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 lubricants and wetting agents in the rubber and textile industries. PEG-600, when added to electrolytes in the metal industry, enhances the grinding effect and improves the shine of metal surfaces.
6. PEG-1000 and PEG-1500 are used as matrices or lubricants/softeners in the pharmaceutical, textile, and cosmetic industries; as dispersants in the paint industry; and improve the water dispersibility and flexibility of resins, with a usage of 20-30%. They can enhance the solubility of dyes in inks, reduce volatility, particularly suitable for wax paper and stamp pad inks, and 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 for metal processing, lubricants for metal wire drawing, stamping, or shaping, cutting fluids, and as polishing agents, welders, etc. In the paper industry, they serve as lubricants and also as hot melt adhesives to enhance rapid rewetting capability.
8. PEG-4000 and PEG-6000 are used as matrices in the pharmaceutical and cosmetic industries for adjusting viscosity and melting points. They serve as lubricants and coolants in the rubber and metal processing industries, and as dispersants and emulsifiers in the production of pesticides and pigments. In the textile industry, they are used as antistatic agents and lubricants.
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 pesticide and pigment industries; and as an antistatic agent and lubricant in the textile industry.
