[performance and Application]
1. Polyethylene glycol series products can be used in pharmaceuticals. Polyethylene glycol with relatively low molecular weight can be used as solvent, cosolvent, o / w emulsifier and stabilizer, cement suspension, emulsion, injection, etc., as well as water-soluble ointment matrix and suppository matrix. Relatively high molecular weight solid waxy polyethylene glycol is often used to increase the viscosity and curing of low molecular weight liquid PEG and to compensate other drugs. For drugs that are insoluble in water, this product can be used as the carrier of solid dispersant to achieve the purpose of solid dispersion. PEG4000 and PEG6000 are good coating materials, hydrophilic polishing materials, membrane materials and capsule materials, plasticizers, lubricants and drop pill matrices for the preparation of tablets, pills, capsules, microcapsules and so on.
2. PEG4000 and PEG6000 are used as excipients in the pharmaceutical industry, as suppositories and pastes, in the paper industry as finishing agents to increase the gloss and smoothness of the paper, and as additives in the rubber industry to increase the lubricity and plasticity of rubber products, reduce power consumption in the processing process, and prolong the service life of rubber products.
3. Polyethylene glycol series products can be used as raw materials of ester surfactants.
4. PEG-200 can be used as a medium for organic synthesis and a heat carrier with higher requirements, as moisturizing agent, inorganic salt solubilizer and viscosity regulator in daily chemical industry, as softener and antistatic agent in textile industry, and as wetting agent in papermaking and pesticide industry.
5. PEG-400, PEG-600 and PEG-800 are used as substrates for medicine and cosmetics, lubricants and wetting agents for rubber and textile industries. The addition of PEG-600 to the electrolyte in the metal industry can enhance the grinding effect and enhance the gloss of the metal surface.
6. PEG-1000 and PEG-1500 are used as substrates or lubricants and softeners in pharmaceutical, textile and cosmetic industries, as dispersants in paint industry, and improve the water dispersibility and flexibility of resins with a dosage of 2030%. Ink can improve the solubility of dyes and reduce their volatility, especially in wax paper and printing table inks, and can also be used to adjust ink consistency in ballpoint pen inks. It is used as dispersant in rubber industry to promote vulcanization and as dispersant for carbon black filling.
7. PEG-2000 and PEG-3000 are used as casting agents for metal processing, lubricants and cutting fluids for metal drawing, stamping or molding, grinding, cooling, lubricating polishing agents, welding agents, etc., as lubricants in the paper industry, and as hot melt adhesives to increase rapid re-wetting ability.
8. PEG-4000 and PEG-6000 are used as matrix in pharmaceutical and cosmetic industry to adjust viscosity and melting point, as lubricant and coolant in rubber and metal processing industry, as dispersant and emulsifier in pesticide and pigment industry, and as antistatic agent and lubricant in textile industry.
9. PEG8000 is used as matrix in pharmaceutical and cosmetic industry, regulating viscosity and melting point, lubricant and coolant in rubber and metal processing industry, dispersant and emulsifier in pesticide and pigment industry, antistatic agent and lubricant in textile industry.
