【Application】

1. Polyethylene glycol series products can be used in medicine. Polyethylene glycol with low relative molecular weight can be used as solvent, cosolvent, O / W emulsifier and stabilizer for making cement suspension, emulsion, injection, etc. it can also be used as water-soluble ointment matrix and suppository matrix. Solid waxy polyethylene glycol with high relative molecular weight is often used to increase the viscosity and solidity of low molecular weight liquid peg and compensate other drugs; For drugs that are not easy to dissolve 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 and capsule materials, plasticizers, lubricants and dropping pill matrix, which are used to prepare tablets, pills, capsules, microcapsules, etc.

2. PEG4000 and PEG6000 are used as excipients in the pharmaceutical industry for the preparation of suppositories and pastes; Used as a finishing agent in the paper industry to increase the luster and smoothness of paper; As an additive in the rubber industry, it can increase the lubricity and plasticity of rubber products, reduce the 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 for ester surfactants.

4. PEG-200 can be used as organic synthesis medium and heat carrier with high requirements. It can be used as moisturizer, inorganic salt solubilizer and viscosity regulator in daily chemical industry; Used as softener and antistatic agent in textile industry; It is used 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 industry and textile industry. The addition of PEG-600 to electrolyte in metal industry can enhance the grinding effect and enhance the luster of metal surface.

6. PEG-1000 and PEG-1500 are used as matrix or lubricant and softener in pharmaceutical, textile and cosmetic industries; Used as dispersant in coating industry; Improve the water dispersion and flexibility of the resin, with the dosage of 20-30%; The ink can improve the solubility of dyes and reduce their volatility. It is especially suitable for wax paper and printing ink, and can also be used to adjust the viscosity of ink in ballpoint pen ink; It is used as dispersant in rubber industry to promote vulcanization and as dispersant of carbon black filler.

7. PEG-2000 and peg-3000 are used as mold agent for metal processing, lubricant and cutting fluid for metal wire drawing, stamping or forming, grinding, cooling, lubricating, polishing agent, welding agent, etc; It is used as a lubricant in the paper industry and also as a hot-melt adhesive to increase the rapid rewetting ability.

8. PEG-4000 and PEG-6000 are used as substrates in pharmaceutical and cosmetic industry to adjust viscosity and melting point; Used as lubricant and coolant in rubber and metal processing industry, dispersant and emulsifier in pesticide and pigment industry; Used as antistatic agent and lubricant in textile industry.

9. PEG8000 is used as matrix in pharmaceutical and cosmetic industry to adjust viscosity and melting point; Used as lubricant and coolant in rubber and metal processing industry, dispersant and emulsifier in pesticide and pigment industry; Used as antistatic agent and lubricant in textile industry.
