Polyethylene Glycol PEG4000 (Jiahua)

　　Polyethylene Glycol PEG4000 (Jiahua) 

　　OVERVIEW

　　Polyethylene Glycol-4000 (Macrogol 4000) is a white waxy solid flake or granular powder with a slight peculiar odor. Polyethylene glycol is a non-ionic, water-soluble polymer and has good compatibility with many organic components. It is slightly hygroscopic. Melts easily when exposed to heat. Soluble in water and ethanol, insoluble in ether. Relative density (d2525) 1.212. melting point 54-58 ℃. Viscosity(99℃) 76～110μm2/s. Flash point(open cup) >246℃.

　　Polyethylene glycol PEG4000 (Jiahua)

　　English name: Polyethylene glycol 4000;PEG 4000

　　Alias: Polyoxyethylene; Polyethylene oxide

　　Molecular Formula: H(OCH2CH2)nOH

　　Molecular weight: ~4000

　　Appearance：White or light yellow hard waxy solid or granules

　　Performance and application

　　1、Polyethylene glycol series products can be used in pharmaceuticals. Relatively low molecular weight polyethylene glycol can be used as solvents, co-solvents, o/w emulsifiers and stabilizers for the production of cement suspensions, flocculants, emulsions, injections, etc., also used as a water-soluble ointment base and suppository base, relative molecular weight of the solid waxy polyethylene glycol is often used to increase the viscosity of low molecular weight liquid PEG and solidification, as well as external compensation of other medicines; for the drugs that are not easily soluble in water, this product can be used as a solid dispersant. This product can be used as the carrier of solid dispersant to achieve solid dispersion, PEG4000, PEG6000 is a good coating material, hydrophilic polishing materials, film and capsule materials, plasticizers, lubricants and dropping pills substrate, used in the preparation of tablets, pills, capsules, microcapsules and so on.

　　2、Polyethylene glycol series products can be used as raw materials for ester-type surfactants.

　　3, PEG-200 can be used as the medium of organic synthesis and heat carrier with high requirements, used as humectant, inorganic salt solubilizer, viscosity regulator in daily-use chemical industry; used as softener, antistatic agent in textile industry; used as wetting agent in paper making and pesticide industry.

　　4, PEG-400, PEG-600, PEG-800 used as pharmaceutical and cosmetic substrates, rubber industry and textile industry lubricants and wetting agents, PEG-600 in the metal industry in the electrolyte can enhance the effect of abrasive, enhance the luster of the metal surface.

　　5, PEG-1000, PEG-1500 in the pharmaceutical, textile, cosmetic industry as a substrate or lubricant, softener; used as a dispersant in the paint industry to improve the water dispersibility of the resin, flexibility, dosage of 10-30%; ink can improve the solubility of dyes, reduce its volatility, in wax paper and printing ink is particularly suitable for the ink, but also in the ball-point pen ink as a viscosity of the ink; in the ink can be used to enhance the dissolution of dye, reduce its volatility, in waxed paper and printing ink, also in ballpoint pen ink as a regulator of ink It can also be used in ball-point pen ink to adjust the viscosity of ink; it can be used as dispersant in rubber industry to promote vulcanization and used as dispersant of carbon black filling material.

　　6, PEG-2000, PEG-3000 used as metal processing molding agent, metal drawing, stamping or molding lubricants and cutting fluids, grinding and cooling lubricant polishing agent, welding agent, etc.; used as a lubricant in the paper industry, also used as a hot-melt binder to increase the re-wetting ability of the fast.

　　7, PEG-4000, PEG-6000 in the pharmaceutical and cosmetic industry as a substrate, to regulate the viscosity, melting point of the role; used as a finishing agent in the paper industry, to increase the luster and smoothness of paper; in the rubber industry as an additive to increase the lubricity and plasticity of rubber products to reduce the power consumption in the process, to extend the service life of the rubber products; in the metal processing industry Used as lubricant and coolant in metal processing industry; used as dispersant and emulsifier in pesticide and pigment industry; used as antistatic agent and lubricant in textile industry.

　　8, PEG8000 in the pharmaceutical, cosmetic industry as a substrate, to regulate the viscosity, melting point of the role; in the rubber, metal processing industry as a lubricant, coolant, pesticides, pigments, industrial production as a dispersant, emulsifier; in the textile industry as an antistatic agent, lubricants and so on.
