Properties and applications of industrial grade polyethylene glycol

Polyethylene glycol series products can be used in pharmaceutical. Polyethylene glycol with low relative molecular weight can be used as solvent, cosolvent, dispersant, o/w emulsifier and stabilizer for the production of cement suspension, emulsion, injection, etc., and also used as water-soluble ointment substrate and suppository substrate. Solid waxy polyethylene glycol with high relative molecular weight is often used to increase the viscosity and solidification of low molecular weight liquid PEG. And other compensatory drugs; For drugs not easy to dissolve in water, the product can be used as the carrier of solid dispersant, in order to achieve the purpose of solid dispersion, PEG4000, PEG6000 is a good coating material, hydrophilic polishing material, film material and capsule material, plasticizer, lubricant and dripping pill matrix, used for the preparation of tablets, pills, capsules, microcapsules, etc.

PEG4000, PEG6000 in the pharmaceutical industry as excipients, used as suppositories, paste preparation; Used as finishing agent in the paper industry to increase the gloss and smoothness of paper; In the rubber industry as an additive, increase the lubricity and plasticity of rubber products, reduce the power consumption in the process of processing, prolong the service life of rubber products.

Polyethylene glycol series products can be used as the raw material of ester type surfactant.

PEG-200 can be used as a medium for organic synthesis and a heat carrier with higher requirements. It can be used as a moisturizing agent, inorganic salt solvator and viscosity regulator in the daily chemical industry. Used as softener and antistatic agent in textile industry; It is used as a wetting agent in the paper and pesticide industries.

PEG-400, PEG-600 and PEG-800 are used as substrates for medicine and cosmetics, lubricants and wetting agents for rubber industry and textile industry. PEG-600 in metal industry can be added to the electrolyte to enhance the grinding effect, enhance the luster of metal surface.

PEG-1000 and PEG-1500 are used as substrates or lubricants and softeners in the pharmaceutical, textile and cosmetic industries. In the coating industry used as dispersant, improve the water dispersion of resin, flexibility, the amount of 10-30%; Ink can improve the solubility of dye, reduce its volatility, in wax paper and printing table ink is especially suitable, can also be used in ballpoint pen ink for adjusting ink viscosity; In rubber industry as a dispersant, promote vulcanization, used as a dispersant for carbon black fillers.

PEG-2000 and PEG-3000 are used as casting agents for metal processing, lubricants and cutting fluids for metal drawing, stamping or forming, grinding, cooling, lubricating polishers, welding agents, etc. Used in the paper industry as a lubricant, etc., but also as a hot melt adhesive to increase rapid rewetting ability.

 PEG-4000, PEG-6000 and PEG-8000 are used as substrates in pharmaceutical and cosmetic industry, which play the role of adjusting viscosity and melting point. It is used as lubricant and coolant in rubber and metal processing industry, and as dispersant and emulsifier in pesticide and pigment industry production. Used in textile industry as antistatic agent, lubricant, etc.
