Manufacturer Provide Raw Powder CAS25322-68-3 Polyethylene Glycol Peg 200
Introduction
Polyethylene glycol is a kind of high molecular polymer, the chemical formula is HO(CH2CH2O)nH, non-irritating, slightly bitter taste, good water solubility, and good compatibility with many organic components. It has excellent lubricity, moisture retention, dispersibility, adhesive, can be used as an antistatic agent and softener, etc. It is widely used in cosmetics, pharmacy, pesticide and food processing industries.
Application & Function of Polyethylene glycol
1, polyethylene glycol series products can be used in pharmaceutical.Low relative molecular weight of polyethylene glycol (PEG) can be used as a solvent, cosolvent, o/w emulsifier and stabilizer, suspension, emulsion, used to make cement injection, etc., are also used as a water-soluble ointment and suppository matrix, the matrix of high relative molecular weight solid waxy polyethylene glycol (PEG) is often used to increase the PEG viscosity and low molecular weight liquid to solid, and of other drugs;PEG4000, PEG6000 are good coating materials, hydrophilic polishing materials, film and capsule materials, plasticizer, lubricant and dropping pill matrix, used for preparing tablets, pills, capsules, microcapsules, etc.
2. PEG4000 and PEG6000 are used as expregents in the pharmaceutical industry for the preparation of suppositories and ointments;Used in the paper industry as a finishing agent to increase the gloss and smoothness of paper;As an additive in rubber industry, it can increase the lubricity and plasticity of rubber products, reduce the power consumption during processing, and extend the service life of rubber products.
3. Polyethylene glycol series can be used as the raw material of ester surfactant.
4. Peg-200 can be used as a medium for organic synthesis and a heat carrier with higher requirements, as a humectant, solvent adding inorganic salt and viscosity regulator in daily chemical industry;Used as softener and antistatic agent in textile industry;Used as wetting agent in paper industry and pesticide industry.
5. Peg-400, peg-600 and peg-800 are used as medical and cosmetic substrates, lubricants and wetting agents for the rubber and textile industries.Peg-600 in the metal industry in the electrolyte can enhance the grinding effect, enhance the gloss of the metal surface.
6. Peg-1000 and peg-1500 are used as matrix or lubricant or softener in pharmaceutical, textile and cosmetic industries;Used as dispersant in coating industry;Improve the water dispersion and flexibility of the resin, the dosage is 20~30%;Ink can improve the solubility of dye, reduce its volatility, especially suitable for wax paper and printing ink, can also be used in ballpoint pen ink for adjusting ink viscosity;Used as dispersant in rubber industry to promote vulcanization and as dispersant for carbon black fillers.
7. Peg-2000 and peg-3000 are used as casting agent for metal processing, lubricant for metal drawing, stamping or forming, and cutting fluid, polishing agent for grinding, cooling and lubrication, welding agent, etc.;Used in the paper industry as lubricants, etc., but also as hot melt adhesives to increase rapid rewetting capacity.
8. Peg-4000 and peg-6000 are used as matrixes in the pharmaceutical and cosmetic industries to regulate the viscosity and melting point;It is 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 a substrate in the pharmaceutical and cosmetic industries to regulate the viscosity and melting point;It is 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.
