Performance & Applications
1. Polyethylene glycol (PEG) series products are suitable for pharmaceuticals. 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 compensating 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 objectives. PEG 4000 and PEG 6000 are excellent for coating materials, hydrophilic polishing materials, film materials, capsules, plasticizers, lubricants, and matrix for droplets, used in the preparation of tablets, capsules, microcapsules, and more.
2. PEG 4000 and PEG 6000 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 prolong 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 be used as a medium for organic synthesis and a high-demand thermal carrier; it serves as a humectant, an inorganic salt solubilizer, and a viscosity regulator in the daily chemical industry. In the textile industry, it acts as a softener and an anti-static agent; and in the papermaking and pesticide industries, it functions as a wetting agent.
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 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; to improve the water dispersibility and flexibility of resins, typically at a rate of 20-30%; they enhance the solubility of dyes in inks, reduce volatility, and are particularly suitable for wax paper and stamp pad inks, as well as for adjusting the viscosity of ballpoint pen inks. In the rubber industry, they act as dispersants to promote vulcanization 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 drawing, stamping, or forming, 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 rapid re-wetting capabilities.
8. PEG-4000 and PEG-6000 are used as bases in pharmaceutical and cosmetic production to adjust viscosity and melting points; as lubricants and coolants in rubber and metal processing industries; as dispersants and emulsifiers in pesticide 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 cosmetics industry 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.
