Product Description
Polyethylene glycol is a kind of high polymer, the chemical formula is HO(CH2CH2O) NH, non-irritating, slightly bitter taste, with good water solubility, and many organic components have good compatibility.It has excellent lubricity, moisture
retention,dispersion and adhesion
Polyethylene glycol series PEG200 PEG400 PEG600 PEG800
Product performance:This series product non-toxic, without excitant,soluble in water ethanol and a variety of organic solvents,insoluble in most of the fatty hydrocarbon and eth yl ether .in accordance with different relative molecular mass and different nature.with the increase of moecular weight of the moisture absorption ability,and the corresponding lower solubility ,and the fresszing point ,relative density ,flash point and viscosity increase.

1, polyethylene glycol series products can be used for 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 medicine; For the medicine that is not easy to dissolve in water, this product can be used as the carrier of solid dispersant, in order to achieve the purpose of solid dispersant, PEG4000, PEG6000 is a good coating material, hydrophilic polishing material, film material and capsule material, plasticizer, lubricant and dropping pill matrix, used for preparing tablets, pills, capsules, microcapsules and so on.
2, polyethylene glycol series products can be used as raw materials of ester surfactant.
3. Peg-200 can be used as a medium for organic synthesis and a heat carrier with high requirements. It can be used as a moisturizing agent, inorganic salt solvent, viscosity regulator in daily chemical industry. Used as softener and antistatic agent in textile industry; It is used as a wetting agent in papermaking and pesticide industry.
4, PEG-400, PEG-600, PEG-800 used as a coating and cosmetics matrix, rubber industry and textile industry lubricant and wetting agent. Peg-600 can enhance the grinding effect and enhance the luster of metal surface by adding electrolyte in metal industry.
5, PEG-1000, PEG-1500 used as a matrix or lubricant, softener in the textile and cosmetic industry; Used as a dispersant in the coating industry, improve the water dispersity of the resin, flexibility, dosage of 10~30%; Ink can improve the solubility of dye, reduce its volatility, especially in wax paper and printing ink, can also be used to adjust the viscosity of ink in ballpoint ink; In the rubber industry as a dispersant, promote vulcanization, used as a dispersant of carbon black filling.
6, PEG-2000, PEG-3000 used as metal processing casting agent, metal drawing, stamping or forming lubricant and cutting fluid, grinding cooling lubrication polishing agent, welding agent, etc.; Used as lubricants in the paper industry, etc., and also as hot melt adhesives to increase rapid rewetting capacity.
7, PEG-4000, PEG-6000 used as a matrix in the cosmetics industry production, play a role in regulating the viscosity, melting point; Used as a 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; Used as lubricant and coolant in metal processing industry, used as dispersant and emulsifier in pesticide and pigment industrial production; Used as antistatic agent, lubricant and so on in textile industry.
8, PEG8000 in medicine, cosmetics industrial production as a matrix, play a role in adjusting the viscosity, melting point; Used as lubricant and coolant in rubber and metal processing industry, used as dispersant and emulsifier in pesticide and pigment industrial production; Used as antistatic agent, lubricant and so on in textile industry.
